Methods for increasing the yield of almond trees by the application of certain plant growth regulators are disclosed.
In one embodiment, a brassinosteroid is applied to a variety of the species Prunus dulcis in the growth stage two weeks after full bloom. In another embodiment, the almond trees are treated at the time of petal fall with a brassinosteroid during the formation the ovaries and nutlets. Non-brassinosteroid plant growth regulators such as Forchlorfenuron and Gibberellic acid may be applied with a brassinosteroid to further promote growth.
The inventors hypothesize that changes in reproductive physiology such as increasing pollen tube growth and pollen germination rates that ultimately result in greater crop yield are promoted by applications of brassinosteroids.
本发明公开了通过施用某些植物生长调节剂提高杏树产量的方法。
在一个实施方案中,在杏树完全开花后两周的生长阶段对其施用黄铜类固醇。在另一个实施方案中,在杏树花瓣脱落时,在子房和小坚果形成期间使用黄铜类固醇处理杏树。非黄铜类固醇植物生长调节剂,如氟磺隆(Forchlorfenuron)和赤霉素(Gibberellic acid)可与黄铜类固醇一起施用,以进一步促进生长。
本发明者假设,应用黄铜类固醇可促进生殖生理的变化,如增加花粉管的生长和花粉发芽率,最终提高作物产量。
