| 摘 要： | 对羟基苯甲酸是导致草莓连作障碍的自毒物质,快速降解连作土壤中积累的对羟基苯甲酸,有利于有效控制连作草莓根部病害的发生。本研究筛选出对羟基苯甲酸降解菌菌株B3512,利用盆栽试验研究了其对对羟基苯甲酸的降解效果。结果表明菌株B3512在48 h内的对羟基苯甲酸降解率达95.7%。在含有对羟基苯甲酸的基质中接种B3512,能通过降解对羟基苯甲酸,增强根系活力、降低根系细胞膜渗透性,明显提高组培苗根长、单株叶面积、株高和植株干重等生长指标,说明菌株B3512能有效缓解对羟基苯甲酸的自毒作用。

| Abstract: | 4-Hydroxybenzoic acid was one of the important auto-toxic chemicals which causes replant disease of strawberry.If it can be depredated in replant soil rapidly,root diseases of strawberry would be reduced.A bacterium B3512 to depredate 4-Hydroxybenzoic acid was screened out,and pot-culture experiment was carried out to investigate its depredating effects.The result showed that B3512 has high-degradation-efficiency to 4-Hydroxybenzoic acid.The degradation rate could reach by 95.7% after 48 hours.The root acti... |
