The influence of chlorophenoxy herbicides MCPA on creeping bentgrass physiological index

摘要

In this article, we studied to different concentrations of MCPA to creeping bentgrass Growth. Through the creeping bentgrass in four different periods of chlorophyll content, MDA and soluble sugar content determination. This test result showed: With the MCPA concentration increases, creeping bentgrass decline of chlorophyll content in the same period of growth, MDA and soluble sugar content increased. MCPA used after the early pair of creeping bentgrass growth is large, to put off with MCPA handle time, to affect to creeping bentgrass growth is gradually decreased.
