Embodiment approach

[0044] When the low-light cultivation method of the present invention is carried out, any cultivation method may be used as long as the active ingredients such as organic acids and sugars contained in the above-mentioned plant growth promoter can be absorbed by plants. For example, cultivation by foliage treatment by applying the above-mentioned plant growth promoter to leaves and stems, and soil-treatment cultivation by applying the above-mentioned plant growth promoter to soil on which the plant grows, and the like. It can also be absorbed by the roots through hydroponics.

[0045] When implementing the cultivation method of plants of the present invention, in addition to the above-mentioned plant growth promoters, if necessary, known various pesticides, fertilizers (organic fertilizers or inorganic fertilizers), plant activators, etc. can be further added to the soil, hydroponics, etc. liquid etc. to carry out.

Embodiment 1

[0050] Embodiment 1 low-light cultivation experiment

[0051] As plants, young shoots (7 days after germination) of morning glory (Pharbitis nil var. Violet) were used. The experiment was carried out in an incubator (low temperature 23° C.), with a light cycle (200 lux) of 14 hours and a dark cycle of 10 hours a day. Seeds of morning glory [purchased from Kyoto Marutane Co., Ltd.] were sown in black plastic pots (commercially available No. 105: diameter 105 cm, height 90 cm). The medium uses vermiculite (the wet weight of the vermiculite in the basin is 350g).

[0052] The test solution is 250ml per pot once, and it is applied to the pot once every 4 days. As the test data, the data obtained by growing 10 morning glory sprouts (seedlings) in one pot were used. The number of new shoots lodging was calculated according to the number of days after the start of the test. The standard for lodging is when the hypocotyl (leaf axis under the cotyledons) of the seedlings and the co...

Embodiment 2

[0076] Aminolevulinic acid, which was conventionally used in low-light cultivation, and citric acid and sucrose, which showed the highest effect in the above-mentioned Example 1, were used for low-light cultivation using the foliage plant Ficus benjamina.

[0077] Amino-levulinic acid, citric acid, and sucrose were added to the inorganic solution (1000-fold dilution of VIGOA LIFE V) in appropriate amounts to prepare three reagents, and the inorganic solution was used as a contrast reagent (reagent 1: aminolevulinic acid was dissolved in the inorganic solution , reagent 2: citric acid dissolved in the inorganic solution, reagent 3: citric acid and sucrose dissolved in the inorganic solution).

[0078] The concentration of citric acid in each reagent was 5 mM, the concentration of sucrose was 3%, and the concentration of aminolevulinic acid was 100 ppm. The pH value of the reagent containing citric acid (reagent 2 and reagent 3) was adjusted to 5.0 with potassium hydroxide.

Abstract

A method for the low light cultivation of a plant under low light level conditions while providing a plant growth promoting agent to the plant, wherein the plant growth promoting agent comprises at leas one selected from the group consisting of citric acid, malic acid and succinic acid.

Description

technical field [0001] The invention relates to a low-illuminance cultivation method for applying a plant growth promoter to plants and cultivating plants under low-illumination conditions. Background technique [0002] The basic environmental factors necessary for plant growth and development can be listed as light, water, temperature, soil and so on. When these conditions of plants are balanced and sufficient, their growth and development can be maintained and promoted. Therefore, under the condition that any one of the above-mentioned conditions is deficient, the plant will be subjected to some kind of stress, thereby hindering its growth. [0003] Among them, for photosynthetic plants, light (illumination conditions) is a particularly important environmental factor. When the plants cannot receive sufficient light due to insufficient sunlight, the plants will be under weak light stress. For example, foliage plants, potted plants, etc. have many opportunities to be broug...
