Effects of Isoproturon on Cabbage Growth and Development and Physiological Index

Abstract：In order to rationally use isoproturon and avoid the impact on the following crops,indoor culture was conducted to investigate the effects of different concentrations of isoproturon(1.562 5,3.125 0,6.250 0,12.500 0,25.000 0,50.000 0 g/L) on cabbage root length,bud length,chlorophyll content,malondialdehyde content and soluble sugar content.The results showed that the inhibition degree of the cabbage bud length and root length was positively correlated with the concentration of isoproturon,and the LC10 were 0.486 1 g/L and 0.233 1 g/L,respectively.With isoproturon concentration increasing,the chlorophyll content showed a tendency of increasing and then decreasing.When the isoproturon concentration was 50.000 0 g/L,the chlorophyll content decreased by 56.16％.With the isoproturon concentration increasing,the contents of soluble sugar and malondialdehyde (MDA) showed an increasing tendency.In comparison with the control using water,when the isoproturon concentrations were 1.562 5,3.125 0,6.250 0,12.500 0,25.000 0,50.000 0 g/L,the soluble sugar content respectively increased by 13.86％,25.97％,42.79％,43.25％,43.81％,74.31％,and the MDA content respectively increased by 14.20％,27.27％,53.13％,53.41％,53.98％,111.36％.Thus,isoproturon significantly inhibited cabbage root length and bud length,increased MDA content and soluble sugar content,but the low concentrations (1.562 5,3.125 0 g/L) had positive effect on the chlorophyll content.
