中文摘要:
      以24 种植物提取物为材料,测定其对几种植物病原菌的抑制活性。结果表明,在供试质量浓度为5 mg/mL 时,山茶、腊梅、香莓、山合欢提取物的抑制效果最好,它们都对其中一种供试病原菌菌丝生长的抑制率超过80%。其中山茶叶提取物对至少3种供试菌菌丝生长抑制率相对优于其他供试植物提取物,尤其对苹果腐霉病菌和小麦赤霉病菌抑制率在80%以上。山茶、腊梅、香莓、山合欢提取物中含有农用抗菌成分且抑菌效果较好,可以应用于无公害植物源杀菌剂的开发。
英文摘要:
      Tested with 24 kinds of plant extracts,the biological activity of the extracts on several plant pathogens were detected. The inhibitory effect of Camellia japonica, Chimonanthus praecox,Rubus pungens var. oldhamii and Albizia kalkora (Roxb.)Prain extracts were best and they had more than 80% inhibiting rates to one tested pathogens at the concentration of 5 mg/mL. The inhibition rate of Camellia japonica extracts was better than that of the other plant extracts to three tested pathogen.which was above 80% to Valsa mali Miyabe et Yamada and Fusarium graminearum. The Camellia japonica, Chimonanthus praecox, Rubus pungens var.oldhamii and Albizia kalkora (Roxb.)Prain extracts contained agricultural antibacterial composition and had wide antimicrobial spectrum.which could be used as non- pollution botanical fungicides.
