Study on the Action of Antidote T to the Injury of Clomazone on Maize Plant by Fluorescence Spectrophotometric Analysis

After treating with clomazone and antidote T, the physiological changes of maize plants were studied by examining the dynamic characteristics of chlorophyll and fluorescence spectrum. The concentration of chlorophyll came down and the r atio of fluorescence strength to concentration of chlorophyll raised up as the c oncentration of clomazone increased. The injury from clomazone could be alleviat ed by antidote T.
