1998～ 1999年 ,通过测定 4种中间砧红富士苹果叶片的变色指数与生理生化变化 ,结果表明 :秋季各中间砧红富士苹果叶片的变色指数逐渐增大、可溶性糖含量逐渐升高 ,而净光合速率、叶绿素、淀粉、可溶性蛋白质含量逐渐降低 ;SH系中间砧的矮化程度影响红富士苹果叶片的变色指数以及叶绿素、可溶性糖、淀粉的含量。
From 1998 to 1999, through the determination of the leaf color index and the physiological and biochemical changes of the four kinds of Fused apple, the results showed that the color index of Red Fuji apple gradually increased and the content of soluble sugar increased gradually Photosynthetic rate, chlorophyll, starch and soluble protein content decreased gradually. The degree of dwarfing of SH-type intermediate anvil affected leaf color index, chlorophyll, soluble sugar and starch content of Red Fuji apple.
