通过测定垂序商陆与胜红蓟乙酸乙酯提取物处理后的降香黄檀炭疽病菌内丙二醛含量、蛋白质含量以及4种酶活性,来初步判断垂序商陆与胜红蓟提取物对炭疽病菌的作用机理。结果表明:两种提取物都能在一定程度上破坏炭疽病病原菌膜系统,垂序商陆处理组丙二醛含量在56 h后显著提高,胜红蓟处理组则缓慢增加,略高于对照组;垂序商陆处理组菌体内蛋白质含量先增加,32 h后急剧降低,胜红蓟处理组蛋白质含量从初期开始就少于对照组;两种提取物都能影响菌体的保护性酶活性,两处理组SOD活力都呈现先增高后降低的趋势,CAT活力高于对照组。两组SDH、LDH活力都小于对照组,而垂序商陆处理组SDH、LDH活力小于胜红蓟处...

To judge the action mechanism of ethyl acetate extracts from Phytolacca americana and Ageratum conyzoides against Colletotrichum gloeosporioides, the MAD content, protein content and the activity of 4 kinds of enzymes of the pathogen treated with the extracts were measured. The results showed that the membrane system of the pathogen could be partly destroyed by the extracts of 2 plants; the MDA content of the pathogen treated with the extract of P.americana increased significantly 56 h later, and the MDA content of the pathogen treated with the extract of A.conyzoides increased slowly, slightl...
