    • Abstract
  • The effects of KCl stress on the activities of protective enzymes(SOD,POD and CAT),the content of soluble protein and resistivity of Lilium‘Pollyanna’stigma were studied.The results showed that the activities of the three enzymes were increased by stress in different degree.Compared to control,the SOD activity increased on bloom day and one day after anthesis and significantly increased on the bud stage and two days after anthesis.The POD activity increased significantly on bloom day and one day after anthesis.The CAT activity increased on one day after anthesis and significantly increased on two and three days after anthesis.But the content of soluble protein and resistivity had no significant difference between the control and the treatments.These indicated that KCl treatments retarded membrane lipid peroxidation,delayed the stigma senescence,improved the pollination and fertilization,which correlated with the seed setting.
