摘要: 为有效控制苹果树腐烂病,通过对不同浓度青霉素处理后的感病植株的病原菌的果胶酶和人工培养的病原菌的果胶酶活性的测定.结果表明:不同浓度青霉素液处理对PA液中病源菌分泌果胶酶活性没有直接的抑制作用;不同浓度青霉素液对感病树体上病源菌分泌果胶酶活性有显著的抑制作用,其中经1.2×10 U/L的青霉素液处理后的抑制效果最明显,处理5d时,感病树体的病组织中果胶酶活性比CK下降了82%.

关键词: 青霉素, 苹果树腐烂病, 果胶酶, 活力

Abstract: In order to reduce the apple trees canker effectively,the research compared the activity of pectolases of pathogens under different concentration penicillin which cultivated between sicken trees and PA. Result showed that the activity of pectolases of pathogens in sicken trees was restrained significantly,whereas the activity of pectolases of pathogens in PA was not effected. The best concentration of penicillin was 1. 2 × 10U/L,and the pectolases of pathogens in sicken trees reduced 82 % under this concentration.

Key words: Penicillin, Apple tree canker, Pectolases, Activeness
