【摘要】 光质是影响果树形态建成和品质形成的主导生态因子。形态建成是果实品质形成的物质基础,概述了光质对植物的叶、茎、根和花芽分化等器官的形态建成及其通过光受体和激素调节等方面的作用机理;光质与果实大小、果形指数、可溶性固形物、维生素C、果实色泽及其在膜透性、色素合成过程中的作用机理,以探讨果树形态建成和品质指标的最佳光质,并提出进一步研究的主要问题。更多还原

【Abstract】 Light quality is the major ecological factor which has important influence to the morphogenesis of fruit tree and the formation of fruit quality.Morphogenesis is the basis of the formation of fruit quality.The research reviewed the effect of light quality on the morphogenesis of leaf?stem?root and floral bud differentiation and the regulative action of photoreceptor and hormone in the course;and summarized the action of fruit size?fruit form index?soluble solid?vitamin C?color and the mechanism of membrane permeability?synthesis of pigment with light quality.The will make for investigated the optimal light quality between morphogenesis of fruit tree and fruit quality.Thus,we put forward the key problem of next step.更多还原
