- 摘要:
- 以“丰香”草莓为试材，以前人筛选出的具有较好诱导抗病性效果的摩西球霉(Glomus mosseae)为供试菌根真菌，通过盆栽方法，研究了接种菌根真菌后，草莓根系木质素和羟脯氨酸糖蛋白（HRGP）含量、超氧化物歧化酶（SOD）、过氧化物酶（POD）和过氧化氢酶（CAT）等保护性酶的活性以及电导率的变化，以期为探讨菌根真菌诱导草莓枯萎抗病性机理。结果表明：接种菌根真菌，可有效提高草莓感枯萎病植株的木质素和HRGP含量，SOD、POD和CAT等保护性酶的活性大幅上升，并有效降低了其电导率。
- Abstract:
- Taking strawberry‘Totonka’as material,Glomus mosseae which had better inducing effect of disease resistance as mycorrhizae fungus,the changes of lignin content,HRGP content,SOD,POD,CAT activities and electric conductivity in the root of strawberry after isolated arbuscular mycorrhizae fungu were studied with pot experiment,in order to investigate the mechanism of strawberry fusarium wilt resistance induced by arbuscular mycorrhizae fungus.The results showed that the fungus could effectively improved content of lignin,HRGP content and activities of SOD,POD and CAT,meanwhile,electric conductivity effectively decreased.
