Physiological Characteristic Changes of Leaf and Leaf Sheath at Different Stem Nodes of Maize in the Late Growth Stage
摘要
Abstract
I n o r d e r t o d e v e l o p s u p e r i o r m a i z e v a r i e t i e s a n d p r o m o t e h i g h y i e l d c u l t i v a t i o n , t h e m a i z e h y b r i d Zhengdan 958 of upright-leaf type was used as experimental materials .Physiological characteristic changes of leaf and leaf sheath at different nodes of maize were investigated in the late growth stage .The results showed that chlorophyll content and soluble protein content were decreased ,MDA content was increased during grain filling process .The change range presented as the middle leaf (leaf sheath) < the upper leaf (leaf sheath) < the lower leaf .The lowered range of chlorophyll content and soluble protein content in leaf sheath was much higher than leaf at late grow th stage ,it indicated that stress resistance of leaf sheath was poorer than that of leaf .关键词
