Abstract
Changes in contents of reduced glutathione (GSH) and oxidized glutathione (GSSG) in leaves and stems/roots of cotton seedlings after infection by Fusarium oxysporum f. sp. vasinfectum (Fov) and pretreatment with trifluralin at 2 μg/g soil were studied. GSH and GSSG contents in leaves and stems/roots of cotton seedlings were increased after infection by Fov. GSH level in leaves was mercased rapidly at the earlier stage of infection and decreased latter whereas GSH level in stems/roots was increased progressively. Presowing treatment with trifluralin, which enhanced the resistance to Fusarium wilt, resulted in increased levels of GSH and GSSG both in leaves and stems/roots of cotton seedlings. How ever, no significant difference in increases of GSH and GSSG levels between cotton seedlings of resistant cultivar (cv Zhongmian 12) and susceptible cultivar (cv 6037) and between trifluralin-treated seedlings and untreated one were observed. Therefore it's unlikely that GSH might be related to the resistance and to the trifluralin-induced resistance of cotton seedlings to Fusarium wilt.
