Abstract:: Tomato variety of ‘Alishan’ was used as the experimental material,six different concentrations of 10% berberine (0,8,16,32,64,128 mg·L-1) were set,to study the effect of different concentrations of 10% berberine (BBR) WP on germination rate and the physiological index of tomato enzyme activity of tomato seedlings by plug seedling raising method,and to determine the optimum concentration of 10% berberine for the growth of tomato seedlings.The results showed that,tomato seedlings treated with 32 mg·L-1 and 64 mg·L-1 had the highest emergence rate and the highest emergence rate.32 mg·L-1 10% berberine treatment of tomato seedlings had the highest chlorophyll content and peroxidase activity,which were 0.76 mg·g-1 and 4 802.89 U·g-1 ·min-1FW,increased 16.43%,47.45%,respectively.The pyruvate kinase and α-amylase activities of tomato seedlings treated with 32 mg·L-1 were the lowest,which were 505.18 U·min-1 and 6.22 mg·g-1·min-1,respectively,and decreased 10.77% and 7.95% compared to the control treatment,respectively.It showed that the best 10% berberine concentration in tomato seedlings was 32 mg·L-1.
