[0155] [Methods for promoting plant growth]

[0156] The plant growth regulator of one embodiment of the present invention can be used in agricultural land or non-agricultural land such as dry fields, paddy fields, lawns and orchards. In addition, the plant growth regulator of one embodiment of the present invention can be used by all fertilization methods, for example, it can be used by the following methods: spraying on stems and leaves, mixing into water supply, spraying on soil, injecting into the subsoil using an injector, seed treatment including treatment of bulbs and tubers, and direct fertilization of plants. Therefore, the plant growth promotion method of one embodiment of the present invention includes the step of fertilizing using the above-mentioned plant growth regulator.

[0157] The application by mixing into the water supply is carried out, for example, by supplying water to crops or placing granules into the surface water of paddy fields. In one example, the concentration of compound (I) in the water supply is 0.1 mg / L or more, preferably 1 mg / L or more. In addition, the amount of compound (I) used in the case of placing into the surface water is, for example, 0.1 g or more, preferably 1 g or more per 10a of paddy field.

[0158] For application by spraying on the stems and leaves or spraying on the soil, for example, granules are applied to the planting hole or its periphery when transplanting seedlings, or granules and wettable powders are applied to the seeds, plant bodies or soil around the plant bodies. In addition, after spraying on the soil, it is sometimes preferable to stir with the soil. The amount of compound (I) used in the case of spraying on the stems and leaves or spraying on the soil surface is relative to 1m 2 The amount of agricultural and horticultural land is, for example, 0.1 mg or more, preferably 1 mg or more.

[0159] For application by seed treatment, the agent is attached to the seed by mixing and stirring a wettable powder, a powder, etc. with the seed, or by immersing the seed in a diluted wettable powder, etc. In addition, seed treatment also includes seed coating treatment. The amount of compound (I) used in the case of seed treatment is, for example, 0.005 g or more, preferably 0.05 g or more, relative to 100 kg of seeds. For seeds treated with agricultural and horticultural agents, they can be used in the same manner as ordinary seeds.

[0160] It should be noted that the concentration and amount used vary depending on the dosage form, use period, use method, use location, target crop, etc., and therefore may be increased or decreased without being restricted to the above range.

[0161] [Use of plant growth regulators]

[0162] As described above, the plant growth regulator of one embodiment of the present invention exhibits an excellent growth promoting effect in the treated plants. Therefore, the plant growth regulator of one embodiment of the present invention can be used as a biostimulant, for example. In addition, it can also be mixed in fertilizers, soil conditioners, pesticides, etc. for use.

[0163] In this specification, the function of "biostimulant" is mainly intended to improve the vitality, yield and quality of crops. For plants, the function of acting on plant physiology through a different path from fertilizers is different from the function of "fertilizer". "Fertilizer" means "a substance applied in soil cultivation or hydroponic cultivation to provide nutrients to plants", which is a substance that supplements the nutrients needed by plants. In the case of insufficient nutrition of plants, there is an effect that can improve the nutritional status of plants by supplying fertilizers, but in the case of sufficient nutrition of plants to a certain extent, the above effect cannot be foreseen.

[0164] [Plant growth regulator products]

[0165] The plant growth regulator of one embodiment of the present invention can be prepared by separately preparing a preparation containing compound (I) and a preparation containing component (A) and mixing them. Therefore, in plant growth regulation, a plant growth regulating product containing compound (I) and component (A) as a combined preparation for mixed use is also included in one embodiment of the present invention.

[0307] [Evaluation Example 17] Comparison of wheat crop height extension

[0308] The plant growth regulators of Examples 39 to 41 and Comparative Examples 55 to 58 were prepared so as to have the concentrations described in the following Table 17. Commercially available EGT and uracil were used, and pure water was used as a solvent.

[0309] 5 mL of plant growth regulator was added to a 9 cm culture dish covered with filter paper. Ten wheat seeds were sown in each culture dish, and the light period was set to 16 hours and the dark period was set to 8 hours in a constant temperature room set at room temperature of 24°C. Fluorescent lamps (Japan Medical Equipment, LED fluorescent lamp plant fleck 40W type electric bulb color for plant cultivation) were used as light conditions, and the light intensity was set to 5000 lx in the center under the irradiation of the fluorescent lamp.

[0310] The wheat plant height was evaluated 7 days after sowing. The evaluation results are shown in Table 17.

[0311] [Table 17]

[0312]

[0313] As shown in Table 17, the plant growth regulators of Examples 39 to 41 were superior to the plant growth regulators containing only uracil (Comparative Examples 56 to 58) and the plant growth regulator containing only EGT (Comparative Example 55) in that the height of the crop was extended and the plant growth promoting effect was excellent. In addition, the height extension of the crop of the plant growth regulators of Examples 39 to 41 was greater than the theoretical value when mixed, confirming a synergistic effect.

[0314] [Evaluation Example 18] Comparison of wheat crop height extension

[0315] Plant growth regulators of Examples 42 to 49 and Comparative Examples 59 to 67 were prepared to have the concentrations shown in Table 18 below. Commercial products were used for EGT, Cys, GSSG, GB, vitamin B1, and inositol, and pure water was used as a solvent.

[0316] 5 mL of plant growth regulator was added to a 9 cm culture dish covered with filter paper. Ten wheat seeds were sown in each culture dish, and the light period was set to 16 hours and the dark period was set to 8 hours in a constant temperature room set at room temperature of 24°C. Fluorescent lamps (Japan Medical Equipment, LED fluorescent lamp plant fleck 40W type electric bulb color for plant cultivation) were used as light conditions, and the light intensity was set to 5000 lx in the center under the irradiation of the fluorescent lamp.

[0317] The wheat plant height was evaluated 7 days after sowing. The evaluation results are shown in Table 18.

[0318] [Table 18]

[0319]

[0320]

[0321] As shown in Table 18, the plant growth regulators of Examples 42 to 49 have an excellent plant growth promoting effect in that the height of crops is extended compared to the plant growth regulators containing only Cys, GSSG, GB, vitamin B1 or inositol (Comparative Examples 60 to 67) and the plant growth regulator containing only EGT (Comparative Example 59). In addition, the height extension of crops of the plant growth regulators of Examples 42 to 49 is greater than the theoretical value when mixed, confirming a synergistic effect.

[0322] Industrial Applicability

[0323] The present invention has excellent plant growth promotion effect and can be used in the fields of agriculture and horticulture.
