【摘要】 以"阿里山"番茄为试验材料,采用穴盘育苗方式,设置0（CK）、8、16、32、64、128mg·L^-1不同浓度10%小檗碱,分别测定番茄出苗率、生理指标、相关酶活性,确定番茄幼苗生长的最适宜10%小檗碱（BBR）可湿性粉剂浓度。结果表明:32 mg·L^-1和64mg·L^-1处理的番茄幼苗出苗最快,出苗率最高;32mg·L^-1处理下番茄叶绿素含量和过氧化物酶活性均最高,分别为0.76mg·g^-1、4 802.89U·g^-1·min^-1 FW,比CK分别提高16.43%、47.45%。32mg·L^-1处理的番茄幼苗丙酮酸激酶和α-淀粉酶活性均最低,分别为505.18U·min^-1,6.22mg·g^-1·min^-1,比CK分别降低10.77%、7.95%。表明番茄幼苗生长最佳的10%小檗碱浓度为32mg·L^-1。更多还原

【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^-1 FW,increased 16.43%,47.45%,respectively.The pyruvate kinase andα-amylase activities of tomato seedlings treated with32 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.更多还原
