Abstract
Two sugarcane C.V.G15and ROC20were soaked with ethephon in three concentrations0mg /L,100mg /L,400mg /L for24hrs before planting in sand.The results were as follows:During the lst month after planting,the ethephon treatment apparently decreased the content of IAA,GA 3 and Zeatin.It showed that increase in endogenous ethylene but decrease in photosynthetic rate in yong leaf+1,and it also increased the content of moisture,permeability of cell membrane,the activities of acid invertase.So,it inhibited the growth of plants at seedling stage and decreased the stalk height ,leaf areas,dry weight of tops and the activities of roots,greater the inhibition with higher concentration.
