[0173] [content]

[0174] The content of the first component in the formulation can be arbitrarily set according to the dosage form, the application rate to the plant, etc. For example, the formulation preferably contains a first component of 0.01% by mass or more and 90% by mass or less relative to its total mass, and more preferably contains a first component of 0.1% by mass or more and 50% by mass or less relative to its total mass. In addition, the formulation preferably contains a second component of 0.00001% by mass or more and 90% by mass or less relative to its total mass, and more preferably contains a second component of 0.0001% by mass or more and 50% by mass or less relative to its total mass.

[0175] Furthermore, the mass ratio of the second component to the total mass of the first component (second component / first component) can be set to 0.001 or more and 1000 or less, preferably 0.01 or more and 100 or less, more preferably 0.1 or more and 10 or less, and even more preferably 0.5 or more and 5 or less.

[0176] The above-mentioned formulation can be used as a treatment agent while remaining unchanged, or it can be used as a treatment agent prepared by mixing it with the above-mentioned adjuvants or other active ingredients in any way.

[0177] [Manufacturing Method]

[0178] Abiotic stress tolerance enhancers can be prepared by mixing the first and second components. In this case, a solid or liquid carrier can be used to prepare a formulation with a specified dosage form. It should be noted that the first component can also be an extract of microorganisms, plants, or seaweed containing it. Furthermore, the second component can also be an extract of microorganisms, plants, or seaweed containing it. Additionally, extracts of microorganisms, plants, or seaweed containing both the first and second components can also be used as abiotic stress tolerance enhancers.

[0179] It should be noted that the first and second components can be stored and transported in a mixed state, or the first component can be contained in a first container and the second component in a second container, and stored and transported in their unmixed, independent states. Alternatively, a product can be manufactured by packaging (packaging) the first container containing the first component and the second container containing the second component.

[0180] [Methods to improve the tolerance of plants to abiotic stress]

[0181] The aforementioned abiotic stress tolerance enhancer or a formulation containing the abiotic stress tolerance enhancer can be used to enhance the abiotic stress tolerance of a plant by applying the abiotic stress tolerance enhancer to a pre-prepared plant.

[0182] There are no particular restrictions on the method of application. It can be applied by any method, such as spreading it through stems and leaves, mixing it into the water supply, spreading it in the soil, injecting it into the lower soil layer using an injector, treating seeds, bulbs and tubers (propagules), or directly fertilizing the plants.

[0183] When mixed into the water supply, the above-mentioned preparation can be applied to the water supply to crops or the surface water of paddy fields in the form of granules or treatment liquid. For example, the concentration of the first component in the water supply to crops can be set to 0.1 mg / L or more, preferably 1 mg / L or more. Furthermore, when applied to the surface water, the application amount of the first component can be set to 0.1 g or more per 10 years of paddy field, preferably 1 g or more.

[0184] When applying the mixture to the stems and leaves or to the soil, it can be done by applying granules to the planting hole or its surroundings during seedling transplanting, or by applying granules and wettable powders to the soil around the seeds, plant, or plant. Alternatively, the soil and the preparation can be mixed together after spraying. The application rate of the first component when applying the mixture to the stems and leaves or to the soil surface is relative to 1 m². 2 Agricultural and horticultural land can be designated as having a concentration of 0.1 mg or higher, with 1 mg or higher being preferred.

[0185] When treating the propagules, for example, one can simply mix and stir the propagules with a wettable powder or similar agent, or immerse the propagules in a diluted wettable powder. Alternatively, a coating agent containing a solid carrier can be used to coat the propagules. The amount of the first component used in treating the propagules should be 0.005 g or more per 100 kg of seeds, preferably 0.05 g or more.

[0186] The treated plants can be grown under the same conditions used for their growth. Plants cultivated in this way can also be transplanted to other soils or culture media for further cultivation once they have reached a certain stage of growth.

[0187] [Other Implementation Methods]

[0188] It should be noted that the above-described embodiments are exemplary embodiments of the present invention, and the present invention can of course include embodiments other than those described above within the scope of its core technical concept.

[0189] Example

[0190] The present invention will be described in detail based on the embodiments, but the present invention is not limited to these embodiments.

[0191] [Evaluation Example 1] Comparison of tolerance effects to high temperature stress

[0192] The non-biological stress tolerance enhancers of Examples 1, 2, and Comparative Examples 1-3 and 5-7 were adjusted to the concentrations described in Table 1 below. Ergothioneine (EGT), arginine (Arg), and glutamic acid (Glu) were commercially available products, and pure water was used as the solvent.

[0193] In a 60mm diameter, 55mm high plastic pot, add 90mL of seedling potting soil (made by Takii Seed). Sow one individual Arabidopsis thaliana (Col-0) in each pot. Prepare two deep plastic trays, each 160mm diameter and 28mm high.

[0194] In an artificial climate chamber set at 22°C, the light period was set to 16 hours and the dark period to 8 hours. Light conditions were set such that the central area under fluorescent lamp illumination reached a light intensity of 5000 lx. Water was supplied from the bottom, with the water level set at approximately 5 mm. On the 92nd day after sowing, 40 mL of an abiotic stress tolerance enhancer was added instead of water. Two days later, the mixture was exposed to 45°C for 1 hour, and then three days later, to 42°C for 3 hours, thus applying high-temperature stress.

[0195] The number of wilted leaves in Arabidopsis thaliana subjected to high-temperature stress was counted, and the wilting rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 1. The wilting rate and abiotic stress inhibition rate (evaluation value) of the leaves were calculated according to the following formula.

[0196] Leaf wilting rate (%)

[0197] = (Number of wilted leaves / Total number of leaves in the tested plant) × 100

[0198] Inhibition rate of abiotic stress (evaluation value) (%)

[0199] ={1 - (Wilting rate of leaves in the treated area / Wilting rate of leaves in the untreated area)} × 100

[0200] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0201] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0202] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0203] [Table 1]

[0204]

[0205] As shown in Table 1, due to high-temperature stress, wilting was observed in 67% of the leaves of the tested Arabidopsis thaliana (Comparative Example 4). Compared with abiotic stress tolerance enhancers containing only Arg or Glu (Comparative Examples 2 and 3) and abiotic stress tolerance enhancers containing only EGT (Comparative Example 1), the abiotic stress tolerance enhancers of Examples 1 and 2 showed lower wilting rates and superior abiotic stress inhibition rates. Furthermore, the abiotic stress tolerance enhancers of Examples 1 and 2 exceeded the theoretical values ​​when mixed, confirming a synergistic effect.

[0206] [Evaluation Example 2] Comparison of tolerance effects to ultraviolet stress

[0207] The non-biological stress tolerance enhancers of Examples 3 and Comparative Examples 9, 10, 12, and 13 were adjusted to the concentrations described in Table 2 below. EGT and Glu were commercially available products, and pure water was used as the solvent.

[0208] Add 5 mL of pure water to each 9 cm petri dish lined with filter paper, and sow 10 wheat seeds in each dish. Manage the petri dishes in an artificial climate chamber set at 22°C, with a light period of 16 hours and a dark period of 8 hours. Set the light conditions so that the center of the petri dish under fluorescent light has a light intensity of 5000 lx.

[0209] Eight days after sowing, the pure water in the culture dish was removed, and then 5 mL of abiotic stress tolerance enhancer was added. One day later, the dish was irradiated with a 254 nm wavelength ultraviolet light lamp (Toshiba, GL-15) with an ultraviolet radiation intensity of 535 μW / cm². -2 Exposure for 1 hour, thereby subjecting ultraviolet stress.

[0210] Leaves that died 5 days after the application of ultraviolet stress were counted, and the leaf mortality rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 10. The leaf mortality rate and abiotic stress inhibition rate (evaluation rate) were calculated according to the following formula.

[0211] Leaf mortality rate (%)

[0212] = (Number of dead leaves / Total number of leaves in the test plant) × 100

[0213] Inhibition rate of abiotic stress (evaluation value) (%)

[0214] ={1 - (leaf mortality rate in the tested compound-treated area / leaf mortality rate in the untreated area)} × 100

[0215] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0216] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0217] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0218] [Table 2]

[0219]

[0220] As shown in Table 2, physiological disorders such as chlorosis were observed in wheat due to ultraviolet stress, with 48% of the leaves of the tested wheat dying (Comparative Example 11). Compared with the abiotic stress tolerance enhancer containing only Glu (Comparative Example 10) and the abiotic stress tolerance enhancer containing only EGT (Comparative Example 9), the abiotic stress tolerance enhancer of Example 3 showed a lower leaf mortality rate and superior abiotic stress inhibition rate. Furthermore, the abiotic stress tolerance enhancer of Example 3 exceeded the theoretical value when mixed, confirming a synergistic effect.

[0221] [Evaluation Example 3] Comparison of tolerance effects to excessive water stress

[0222] The non-biological stress tolerance enhancers of Examples 4 to 7 and Comparative Examples 15 to 17, and Comparative Examples 19 to 21 were adjusted to the concentrations described in Table 3 below. Commercially available EGT and Glu were used, and pure water was used as the solvent.

[0223] Add 5 mL of pure water to each 9 cm petri dish lined with filter paper, and sow 10 rapeseed seeds in each dish. Manage the petri dishes in an artificial climate chamber set at 22°C, with a light period of 16 hours and a dark period of 8 hours. Set the light conditions so that the center of the petri dish under fluorescent light has a light intensity of 5000 lx.

[0224] Eight days after sowing, the pure water in the petri dish was removed, and then 5 mL of abiotic stress tolerance enhancer was added to the petri dish. One day later, 50 mL of pure water was added to the petri dish to apply excessive water stress.

[0225] Plants surviving 10 days after the application of excessive water stress were counted, and the plant mortality rate was evaluated as an indicator of physiological impairment. The evaluation results are shown in Table 3. The mortality rate and abiotic stress inhibition rate (evaluation value) were calculated according to the following formula.

[0226] Mortality rate (%)

[0227] ={1 - (Number of surviving plants / Number of plants tested)} × 100

[0228] Inhibition rate of abiotic stress (evaluation value) (%)

[0229] ={1 - (mortality rate in the treated area / mortality rate in the untreated area)} × 100

[0230] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0231] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0232] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0233] [Table 3]

[0234]

[0235] As shown in Table 3, physiological disorders such as chlorosis were observed in rapeseed due to excessive water stress, and 84% of the tested rapeseed plants withered (Comparative Example 18). Compared with abiotic stress tolerance enhancers containing only Arg or Glu (Comparative Examples 16 and 17) and abiotic stress tolerance enhancers containing only EGT (Comparative Example 15), the abiotic stress tolerance enhancers of Examples 4, 5, 6, and 7 showed lower mortality rates and superior abiotic stress inhibition rates. Furthermore, the abiotic stress tolerance enhancers of Examples 4 and 6 exceeded the theoretical values ​​when mixed, confirming a synergistic effect.

[0236] [Evaluation Example 4] Comparison of tolerance effects to dryness stress

[0237] The non-biological stress tolerance enhancers of Examples 8 to 15 and Comparative Examples 23 to 31 were adjusted to the concentrations described in Table 4 below. Ergothioneine (EGT), trehalose, methionine (Met), oxidized glutathione (GSSG), γ-aminobutyric acid (GABA), citric acid, ascorbic acid (VitC), and potassium sorbate (sorbic acid) were commercially available, and purified water was used as the solvent.

[0238] Add 150mL of granular potting soil (combined horticultural potting soil) to a plastic pot with sides of 60mm and a height of 66mm, and sow one soybean seed in each pot. Prepare four deep plastic trays with a diameter of 160mm and a height of 28mm.

[0239] Management was carried out in a greenhouse with a room temperature of 25°C. On the 31st day after sowing, 50 mL of abiotic stress tolerance enhancer was added to the deep trays to replace watering, and watering was stopped for the next 5 days to apply desiccation stress.

[0240] The number of dead leaves in soybeans subjected to drought stress was counted, and the leaf mortality rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 4. The leaf mortality rate and abiotic stress inhibition rate (evaluation value) were calculated according to the following formula.

[0241] Leaf mortality rate (%)

[0242] = (Number of dead leaves / Total number of leaves in the test plant) × 100

[0243] Inhibition rate of abiotic stress (evaluation value) (%)

[0244] ={1 - (leaf mortality rate in the tested compound-treated area / leaf mortality rate in the untreated area)} × 100

[0245] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0246] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0247] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0248] [Table 4]

[0249]

[0250] As shown in Table 4, physiological disorders such as necrosis were observed in soybeans due to drought stress, with 56% of the leaves of the tested soybeans dying (Comparative Example 32). Compared with abiotic stress tolerance enhancers containing only trehalose, Met, GSSG, GABA, citric acid, vitamin C, or sorbic acid (Comparative Examples 24, 25, 26, 27, 28, 29, 30, and 31) and abiotic stress tolerance enhancers containing only EGT (Comparative Example 23), the abiotic stress tolerance enhancers of Examples 8, 9, 10, 11, 12, 13, 14, and 15 showed lower leaf mortality rates and superior abiotic stress inhibition rates. Furthermore, the abiotic stress tolerance enhancers of Examples 8, 9, 10, 11, 12, 13, 14, and 15 exceeded the theoretical values ​​when mixed, confirming a synergistic effect.

[0251] [Evaluation Example 5] Comparison of tolerance effects to low temperature stress

[0252] The non-biological stress tolerance enhancers of Examples 16-17 and Comparative Examples 34-36 were adjusted to the concentrations described in Table 5 below. Ergothioneine (EGT), histidine (His), and uracil were commercially available products, and purified water was used as the solvent.

[0253] Add 5 mL of pure water to each 9 cm petri dish lined with filter paper, and sow 20 arugula seeds in each dish. Manage the petri dishes in an artificial climate chamber set at 22°C, with a light period of 16 hours and a dark period of 8 hours. The light conditions are set such that the center of the petri dish receives 5000 lx of light under fluorescent illumination.

[0254] Six days after sowing, the pure water in the culture dish was removed, and then 5 mL of abiotic stress tolerance enhancer was added to the culture dish. After 24 hours, the dish was exposed to 4°C for 48 hours to apply low temperature stress.

[0255] The number of wilted leaves was counted two days after the application of low-temperature stress, and the leaf wilting rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 5. The leaf wilting rate and abiotic stress inhibition rate (evaluation value) were calculated according to the following formula.

[0256] Leaf wilting rate (%)

[0257] = (Number of wilted leaves / Total number of leaves in the tested plant) × 100

[0258] Inhibition rate of abiotic stress (evaluation value) (%)

[0259] ={1 - (Wilting rate of leaves in the treated area / Wilting rate of leaves in the untreated area)} × 100

[0260] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0261] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0262] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0263] [Table 5]

[0264]

[0265] As shown in Table 5, due to low-temperature stress, wilting was observed in 94% of the tested arugula leaves (Comparative Example 37). Compared with abiotic stress tolerance enhancers containing only His or uracil (Comparative Examples 35 and 36) and abiotic stress tolerance enhancers containing only EGT (Comparative Example 34), the abiotic stress tolerance enhancers of Examples 16 and 17 showed lower wilting rates and superior abiotic stress inhibition rates. Furthermore, the abiotic stress tolerance enhancers of Examples 16 and 17 exceeded the theoretical values ​​when mixed, confirming a synergistic effect.

[0266] [Evaluation Example 6] Comparison of tolerance effects to freezing stress

[0267] The non-biological stress tolerance enhancers of Examples 18, 39, and 40 were adjusted to the concentrations described in Table 6 below. Ergothioneine (EGT) and malic acid were commercially available, and purified water was used as the solvent.

[0268] Add 5 mL of pure water to each 9 cm petri dish lined with filter paper, and sow 20 cauliflower (broccoli) seeds in each dish. Manage the petri dishes in an artificial climate chamber set at 22°C, with a light period of 16 hours and a dark period of 8 hours. The light conditions are set such that the center of the petri dish receives 5000 lx of light under fluorescent illumination.

[0269] Six days after sowing, the pure water in the culture dish was removed, and then 5 mL of abiotic stress tolerance enhancer was added to the culture dish. After 24 hours, the dish was exposed to -20°C for 30 minutes, and then after 48 hours, it was exposed to -20°C for 30 minutes, thus applying freezing stress.

[0270] Plants surviving one day after the application of freezing stress were counted, and the plant mortality rate was evaluated as an indicator of physiological impairment. The evaluation results are shown in Table 6. The mortality rate and abiotic stress inhibition rate (evaluation value) were calculated according to the following formula.

[0271] Mortality rate (%)

[0272] ={1 - (Number of surviving plants / Number of plants tested)} × 100

[0273] Inhibition rate of abiotic stress (evaluation value) (%)

[0274] ={1 - (mortality rate in the treated area / mortality rate in the untreated area)} × 100

[0275] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0276] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0277] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0279]

[0280] As shown in Table 6, physiological disturbances such as stem breakage or necrosis were observed in cauliflower due to freezing stress, with 44% of the tested cauliflower samples dying (Comparative Example 41). Compared to the abiotic stress tolerance enhancer containing only malic acid (Comparative Example 40) and the abiotic stress tolerance enhancer containing only EGT (Comparative Example 39), the abiotic stress tolerance enhancer of Example 18 showed a lower mortality rate and superior abiotic stress inhibition rate. Furthermore, the abiotic stress tolerance enhancer of Example 18 exceeded the theoretical value when mixed, confirming a synergistic effect.

[0281] [Evaluation Example 7] Comparison of tolerance effects to excessive nutrient stress

[0283] Add 150mL of granular potting soil (combined horticultural potting soil) to a plastic pot with sides of 60mm and a height of 66mm, and sow one soybean seed in each pot. Prepare two deep plastic trays with a diameter of 160mm and a height of 28mm.

[0284] Management was carried out in a greenhouse with a room temperature of 25°C. On the 31st day after sowing, 50 mL of abiotic stress tolerance enhancer was added to the deep trays instead of water. One day later, liquid fertilizer (HYPONeX, manufactured by Hyponex Japan) was applied at a 5-fold dilution to induce nutrient stress.

[0285] The number of dead leaves in soybeans one day after the application of excessive nutrient stress was counted, and the leaf mortality rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 7. The leaf mortality rate and abiotic stress inhibition rate (evaluation value) were calculated according to the following formula.

[0286] Leaf mortality rate (%)

[0287] = (Number of dead leaves / Total number of leaves in the test plant) × 100

[0288] Inhibition rate of abiotic stress (evaluation value) (%)

[0289] ={1 - (leaf mortality rate in the tested compound-treated area / leaf mortality rate in the untreated area)} × 100

[0290] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0291] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0292] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0293] [Table 7]

[0294]

[0295] As shown in Table 7, physiological disorders such as chlorosis were observed in soybeans due to excessive nutrient stress, with 76% of the leaves of the tested soybeans dying (Comparative Example 49). Compared with abiotic stress tolerance enhancers containing only Pro, 5-ALA, GB, or acetic acid (Comparative Examples 45, 46, 47, and 48) and abiotic stress tolerance enhancers containing only EGT (Comparative Examples 43 and 44), the abiotic stress tolerance enhancers of Examples 19, 20, 21, 22, and 23 showed lower leaf mortality rates and superior abiotic stress inhibition rates.

[0296] [Evaluation Example 8] Comparison of tolerance effects to high temperature stress

[0297] The non-biological stress tolerance enhancers of Examples 24, 25, and Comparative Examples 51 to 54 were adjusted to the concentrations described in Table 8 below. Ergothioneine (EGT), acetic acid, and proline (Pro) were commercially available products, and purified water was used as the solvent.

[0298] Add 90mL of seedling potting soil (made by Takii Seed) to a 60mm diameter, 55mm high plastic pot, and sow one individual tomato (Regina) in each pot. Prepare four deep plastic trays with a diameter of 160mm and a height of 28mm.

[0299] In an artificial climate chamber set at 22°C, the light period was set to 16 hours and the dark period to 8 hours. Light conditions were set so that the central area under fluorescent lamp illumination reached a light intensity of 5000 lx. Water was supplied from the bottom, with the water level set at approximately 5 mm. On the 30th day after sowing, 50 mL of an abiotic stress tolerance enhancer was added to replace the water supply. Two days later, the mixture was exposed to 45°C for 1 hour, followed by exposure to 55°C for 30 minutes, thus applying high-temperature stress.

[0300] The number of wilted leaves in tomatoes subjected to high-temperature stress was counted, and the wilting rate was evaluated as an indicator of physiological disorder. The evaluation results are shown in Table 8. The wilting rate and abiotic stress inhibition rate (evaluation value) of the leaves were calculated according to the following formula.

[0301] Leaf wilting rate (%)

[0302] = (Number of wilted leaves / Total number of leaves in the tested plant) × 100

[0303] Inhibition rate of abiotic stress (evaluation value) (%)

[0304] ={1 - (Wilting rate of leaves in the treated area / Wilting rate of leaves in the untreated area)} × 100

[0305] Next, the synergistic effect of the two compounds was determined using the Colby formula (the formula below):

[0306] Theoretical value of abiotic stress inhibition rate (%) when mixed addition = α + ((100-α)×β) / 100.

[0307] It should be noted that in the above formula, α and β represent the abiotic stress inhibition rate when each compound is added individually.

[0308] [Table 8]

[0309]

[0310] As shown in Table 8, due to high-temperature stress, wilting was observed in 62% of the leaves of the tested tomatoes (Comparative Example 55). Compared with abiotic stress tolerance enhancers containing only acetic acid or Pro (Comparative Examples 53 and 54) and abiotic stress tolerance enhancers containing only EGT (Comparative Examples 51 and 52), the abiotic stress tolerance enhancers of Examples 24 and 25 showed lower wilting rates and superior abiotic stress inhibition rates. Furthermore, the abiotic stress tolerance enhancers of Examples 24 and 25 exceeded the theoretical values ​​when mixed, confirming a synergistic effect.

[0311] This application claims priority to Japanese Patent Application No. 2023-197530, filed November 21, 2023. The matters set forth in the original description and claims of that application are incorporated herein by reference.
