発明の名称 (英語) Plant growth regulator and use thereof 実績あり
発明の概要(英語) 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.
特許請求の範囲(英語) [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.
