板栗雄花芽临界分化期营养物质含量的变化

目的]了解和探索板栗雄花芽分化的生理机制，探讨科学有效地抑制雄花芽分化、促进雌花分化的方法，并为板栗的开花授粉、结实丰产的化学调控及合理的施肥措施提供理论依据。方法]以6年生鄂粟2号板栗（CastaneamollissimaB1．）为试材，在雄花芽临界分化期测定了雄花芽和同期叶芽中碳水化合物（可溶性糖、蔗糖、淀粉）和可溶性蛋白质的含量。结果]板栗雄花芽临界分化期，雄花芽和同期叶芽中碳水化合物和可溶性蛋白质变化趋势相同，且雄花芽中这些物质的含量均高于叶芽。综合可知，一定浓度范围内，可溶性糖、蔗糖和可溶性蛋白的积累促进了雄花芽的分化。结论]板栗雄花芽分化与其营养物质的积累有密切关系，也与叶芽分化有较密切关系。

Research on the Change of the Nutrient Material in Critical Period of Chestnut Male Flower Bud Differentiation

Objective] The theoretical basis of the chemical regulation of pollination and the ratio of the seed-setting for high yield of chestnut and the reasonable fertilization was provided through the research on the scientific and effective inhibition of flower bud differentiation for the promotion of female flower differentiation based on the understanding and exploration of its physiological mechanism.Method] The content of carbohydrate(soluble sugar,sucrose and starch) and soluble protein in the male flower ...
