摘要
试验研究了 8种植物提取液对黑斑病菌、枯萎病菌、炭疽病菌和早疫病菌的生长速率及孢子萌发的抑制作用。结果表明 :蟛蜞菊、辣椒、人参果提取液对病原菌生长的抑制率明显 ,分别达39.19% ,36 .5 4% ,4 4.18% ;马齿苋、蟛蜞菊、辣椒对病原菌孢子萌发的抑制效果明显 ,分别达2 4 .72 % ,2 9.4 5 % ,4 1.74 % ;马齿苋、蟛蜞菊、番石榴对病原菌扩展的抑制率明显 ,分别达 4 2 .17% ,39.5 0 % ,36 .93%。
The studies on the inhibition of 8 kinds of plant extracs to the growth and sprout rate of Alternaria brassicae,Fusariam oxysporum, Colletotrichum lagenarium and Alternaria solani,showed that the extracts of Wedelia chinensis, Capsicum annuum and Manilkara zapota had more obvious inhibition to growth,the pathogenetic fungi,with the repression rate being 39.19%, 36.54%, 44.18% resp.the tentracts of Portulara oleracea,W.and C.were more distinct to sprout rate the pathogenetic fungi,with the remession rate being 24.72%,29.45%,41.74%,resp.P.,W.and Pesidium guajava were more distinct to expend the pathogenetic fungi,wirh the repression rate being 42.17%,39.50%, 36.93% resp..
