在管理良好、植株健壮的条件下,葡萄花芽高节位分化是一个普遍的现象。一年生枝从低节位到高节位均可形成正常的花芽,并能正常开花结果,而且高节位分化花芽对当年的果实品质及次年的花芽分化无不良的影响。合理利用这一特性对促进葡萄幼树早丰产有重要的指导意义。 Under well-managed, robust plant conditions, high differentiation of grape buds is a common phenomenon. The annual branches can form normal flower buds from low node to high node and can flowering normally, and the high node differentiation flower bud has no adverse effect on the fruit quality of the current year and the next year’s flower bud differentiation. Rational use of this feature to promote early young grapevine yield an important guiding significance.
