对2 a生巨峰葡萄自然实生树不同节位叶片叶绿素含量及叶片和韧皮部的可溶性蛋白质含量进行了测定分析。结果表明,童期和成年营养生长期叶片叶绿素含量随节位的上升而降低,生殖生长期叶绿素含量稳定;16~20节(即成年营养生长期)韧皮部可溶性蛋白含量显著低于童期和生殖生长期。
The chlorophyll content and soluble protein content in leaves and phloem of 2-year-old Kyoho grapes natural-bred trees were measured. The results showed that chlorophyll content in vegetative and vegetative vegetative growth stages decreased with the increase of internode stages and the chlorophyll content in reproductive stage was stable. The content of soluble protein in phloem 16 ~ 20 (ie, in adult vegetative stage) was significantly lower than that in childhood and reproductive Growth period.
