植物激素与果树花芽分化

Hormones and Flower-bud Differentiation of Fruit Trees

综述了近十年来果树花芽分化的一些研究进展,主要从细胞分裂素、赤霉素、生长素、脱落酸、乙烯等激素及其平衡等方面介绍花芽分化的研究进展。细胞分裂素和乙烯对果树花芽分化有促进作用;赤霉素则对果树花芽分化有抑制作用;生长素在花芽分化中的作用与营养的输入有关;脱落酸在果树花芽分化中的作用目前意见不一致。

The advances of research on flower-bud differentiation of fruit trees in last ten years is reviewed. It contains relationship between flower-bud differentiation and cytokinin, gibberellin,auxin, abscisci acid,ethylene and hormones balance. Cytokinin and ethylene are helpful to flower-bud differentiation of fruit trees, but gibberellin is not. Auxin＇s function has some relationship with the input of nutrition. Different ideas exist in the role of abscisci acid on flower bud differentiation bud differentiation of fruit trees.
