嫁接茄子根系分泌物对黄萎病菌的化感作用

Allelopathic effects of the root exudates of grafted eggplants on the verticillium wilt,Verticillium dahliae

研究了不同砧木、不同浓度嫁接茄子根系分泌物对茄子黄萎病菌(Verticillium dahliae)孢子萌发和菌丝生长的影响。结果表明,与自根茄相比,所有参试的嫁接茄根系分泌物都不同程度抑制了黄萎病菌孢子萌发和菌丝生长;并且随着根系分泌物浓度的增加,抑制作用增强。

Effects of the root exudates from various rootstocks and at different concentrations on spore germination and mycelial growth of the eggplant verticillium wilt were studied. The root exudates of grafted eggplants inhibited spore germination and mycelial growth of the verticillium wilt. The inhibitory effects were enhanced with increasing concentration of the root exudates.
