| 摘 要： | 用抗药性标记法对6种生防放线菌进行标记,并测定其在黄瓜、小麦、大麦以及大豆体内的定殖能力,发现15—3可以在黄瓜、小麦以及大麦的根部定殖,在黄瓜根部的定殖能力强于在其它两种作物根部的定殖能力。6种生防菌对黄瓜、小麦、大麦以及大豆种子萌发或苗期生长没有明显抑制作用;菌株15—3对大麦、黄瓜以及大豆具有不同程度的促生作用;菌株SE2和A4发酵液对黄瓜的生长有抑制作用。

| Abstract: | Six strains of actino myces candidates with significant biocontrol potential was tagged with antibiotics,fungicides or combination of them.The result showed that cucumber,wheat and barley plant could be colonized by strain 15-3 and the amount of strain 15-3 in root of cucumber was more than that in the other two crops.Six strains of tested actinomyces had no inhibition on germination of seeds and growth in seedling stage of cucumber,wheat,barley and soybean,and the development of tested plants could be promoted by strain 15-3. |
