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.
Claims14
A method for preparing a plant having increased harvest index compared to a harvest index of a wild type plant or untreated plant, comprising the steps of:
- applying oxidized glutathione to a plant, or to soil with which a plant is to be cultivated;
- cultivating the plant,
- wherein a total amount of the applied glutathione with which the plant is cultivated is in the range (i) between 2.5 mg and 1470 mg per one individual plant, or (ii) between 0.82 mg and 1800 mg per one liter of soil;
- measuring an amount of harvest of the plant;
- calculating a harvest index of the plant;
- and
- wherein a plant having a harvest index that is higher than the harvest index of the wild type plant or untreated plant is thereby prepared.
A method for preparing a plant having an increased number of seeds and/or flowers compared to a number of seeds and/or flowers of a wild type plant or untreated plant, comprising the steps of:
- applying oxidized glutathione to a plant, or to soil with which a plant is to be cultivated;
- cultivating the plant,
- wherein a total amount of the applied glutathione with which the plant is cultivated is in the range (i) between 2.5 mg and 1470 mg per one individual plant, or (ii) between 0.82 mg and 1800 mg per one liter of soil;
- measuring the number of seeds and/or the flowers of the plant;
- and
- wherein a plant having a number of seeds and/or flowers that is higher than the number of seeds and/or flowers of the wild type plant or untreated plant is thereby prepared.
A method for preparing a plant having an increased number of lateral shoots and/or tillers compared to a number of lateral shoots and/or tillers of a wild type plant or untreated plant, comprising the steps of:
- applying oxidized glutathione to a plant, or to soil with which a plant is to be cultivated;
- cultivating the plant,
- wherein a total amount of the applied glutathione with which the plant is cultivated is in the range (i) between 2.5 mg and 1470 mg per one individual plant, or (ii) between 0.82 mg and 1800 mg per one liter of soil;
- measuring the number of lateral shoots and/or tillers of the plant;
- and
- wherein a plant having a number of lateral shoots and/or tillers that is higher than the number of lateral shoots and/or tillers of the wild type plant or untreated plant is thereby prepared.
