| 摘 要： | 目的:研究水分胁迫下表油菜素内酯(EBR)对菘蓝相关酶活性和生理指标的影响,为提高菘蓝的抗涝能力提供方法。方法:采用盆栽试验,测定水分胁迫下,不同浓度EBR(0.01、0.050、.10、0.501、.00 mg/L)处理下的菘蓝的抗氧化保护酶(SOD、POD、CAT、APX)、乙醇脱氢酶(ADH)、硝酸还原酶(NR)活性和脯氨酸(Pro)、可溶性蛋白、丙二醛(MDA)的含量。结果:当EBR浓度为0.100、.50 mg/L时,菘蓝的黄叶数最少,随着EBR浓度的增加,抗氧化酶、ADH、NR活性先增后降,Pro、可溶性蛋白含量也呈相同变化趋势,MDA含量变化则与之相反。结论:适宜浓度的EBR能显著提高菘蓝的抗氧化能力,减少水分胁迫造成的伤害。
