Application of cytokinin 6-BA in changing sex ratio of plant flowers

Abstract

The invention discloses application of cytokinin 6-BA in changing sex ratio of plant flowers. In the application, the cytokinin 6-BA is used for regulating the sex ratio of jatropha curcas flowers and increasing the proportion of male and female jatropha curcas flowers. Under a certain condition, the spraying concentration of the cytokinin 6-BA influences the sex ratio of the male flowers to the female flowers and is between 20 mg / L and 100 mg / L, wherein the certain condition is that the age of the plant tree is more than 2 years; the spraying method is to spray the cytokinin 6-BA on the whole jatropha curcas at the bud stage of the first flowers, wherein the drips are small and uniform at the time of spraying, the spraying amount is enough when the sprayed part is wet and fine liquid drops fall, and the spraying time is between 14:30 and 16:30 p.m. in a sunny day; and if rain falls within 36 hours after spraying, the cytokinin 6-BA needs to be sprayed again. The invention solves the problem that the proportion of the male and female jatropha curcas flowers is low and can increase the proportion of the male and female jatropha curcas flowers by 15.89-67.48% and the individual yield by 4-31%.

Description

technical field [0001] The invention belongs to the application field of plant growth regulators, and in particular relates to the application of cytokinin 6-BA in changing the sex ratio of plant flowers. Background technique [0002] There are not many changes in the sex ratio of plant flowers in the prior art. For example, Chinese Patent Publication No. CN101292607A discloses "a method for regulating and controlling the sex ratio of flowers of Jatropha curcas by chemical reagents", which is the effect of ethephon and gibberellin at the same time, but , it is not ideal to improve the ratio of male and female flowers of Jatropha curcas. As one of the plants that can produce biodiesel, Jatropha curcas seeds are rich in oil, the oil has strong fluidity and good quality, and has high research value and economic value. It has been more and more widely cultivated as an energy plant. , and its potential medicinal value is constantly being researched and developed more deeply and ...
