| 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 harvest index of a plant. [claim2] 2. The use as set forth in claim 1, wherein the glutathione is oxidized glutathione. [claim3] 3. The use as set forth in claim 1 or 2, for increasing the number of seeds and/or flowers of a plant. [claim4] 4. The use as set forth in claim 1 or 2, for increasing the number of lateral shoots and/or tillers of a plant. [claim5] 5. A method for preparing a plant having an increased harvest index as compared to that of a wild strain or untreated plant, comprising the steps of: applying glutathione to a plant, or to soil with which a plant is to be cultivated; cultivating the plant; and selecting a plant having a harvest index that is higher than the harvest index of a wild strain or untreated plant. [claim6] 6. The method as set forth in claim 5, wherein the glutathione is oxidized glutathione. [claim7] 7. The method as set forth in any one of claims 5-6, wherein the glutathione is supplied at around a time of transition from vegetative to reproductive development. [claim8] 8. The method as set forth in claim 5, wherein the method is for preparing a plant having an increased number of seeds and/or flowers as compared to that of a wild strain or untreated plant, and comprises the steps of: applying glutathione to a plant, or to soil with which a plant is to be cultivated; cultivating the plant; and selecting a plant having a number of seeds and/or flowers that is higher than the number of seeds and/or flowers of a wild strain or untreated plant. [claim9] 9. The method as set forth in claim 8, wherein the glutathione is oxidized glutathione. [claim10] 10. The method as set forth in claim 5, wherein the method is for preparing a plant having an increased number of lateral shoots and/or tillers as compared to that of a wild strain or untreated plant, and comprises the steps of: applying glutathione to a plant, or to soil with which a plant is to be cultivated; cultivating the plant; and selecting a plant having a number of lateral shoots and/or tillers that is higher than the number of lateral shoots and/or tillers of a wild strain or untreated plant. [claim11] 11. The method as set forth in claim 10, wherein the glutathione is oxidized glutathione. [claim12] 12. The method as set forth in claim 10 or 11, wherein the plant has mutation in a function for synthesizing a plant hormone and/or a function for responding to a plant hormone. [claim13] 13. The method as set forth in claim 12, wherein the plant hormone is gibberellin. |
