不同百合种质资源对灰葡萄孢菌的抗性鉴定及生理生化指标分析
Resistance and physiological-biochemical analysis of Lilium to Botrytis cinerea
摘要
Abstract
[Objective]This study aimed to explore the physiological mechanisms underlying resistance to gray mold in diverse lily germplasms.[Method]Using several wild and cultivated lily varieties as experimental materials and Botrytis cinerea as the test strain,gray mold resistance of detached lily leaves after inoculation was assessed,along with antioxidant enzyme activities and the contents of malondialdehyde(MDA),reactive oxygen species(ROS),and osmotic adjustment substances in eight cultivated lily varieties exhibiting varying levels of resistance.[Result]Seven resistant resources were identified among fifteen wild lily species.Cultivated lilies of the A and LA hybrid series were susceptible,whereas those of the O and OT series were resistant.Superoxide dismutase(SOD)and peroxidase(POD)activities were critical for lily resistance to gray mold;MDA content,superoxide anion radical(O2⁻·)content,and their variation ranges at 48 h post-inoculation served as indicators for screening disease-resistant lilies.[Conclusion]Dis-ease-resistant lilies defend against gray mold by regulating ROS levels and osmotic adjustment substance contents.关键词
