Title Plant growth regulator and use thereof
Abstract A plant growth regulator containing glutathione allows increasing harvest index. This provides a technique for specifying a control factor for a plant, thereby effectively controlling germination, growth, anthesis etc. of the plant.
Scope of claims [claim1]
1. Use of glutathione for increasing the proportion of the weight of a harvest of a plant relative to the weight of the plant as a whole, wherein a glutathione synthesis inhibitor and a phytohormone are not used, wherein the harvest is a seed.

[claim2]
2. The use of claim 1, wherein the glutathione is oxidized glutathione.

[claim3]
3. Use according to claim 1 or 2, characterized in that the plant is a plant used as food.

[claim4]
4. A method for obtaining a plant having a higher ratio of the weight of a harvest to the weight of the whole plant than that of a wild-type plant or a plant not treated with glutathione, comprising the steps of cultivating a plant using glutathione, measuring the ratio of the weight of the harvest to the weight of the whole plant of the plant cultivated in the above-mentioned steps, and selecting a plant having an increased ratio of the weight of the harvest to the weight of the whole plant, wherein the harvest is a seed without using a glutathione synthesis inhibitor and a phytohormone.

[claim5]
5. The method of claim 4, wherein the glutathione is oxidized glutathione.

[claim6]
6. The method according to claim 4, wherein the plant is a plant used as food.

[claim7]
7. The method of claim 4, wherein glutathione is administered intermittently.

[claim8]
8. The method of claim 4, wherein glutathione is administered before and after the transition period from vegetative to reproductive growth.
