4株木霉对人参疫病菌、西洋参锈腐病菌的拮抗作用

Antagonism of Trichoderma Against the Pathogens of Blight of Panax ginseng and Root rust rot of American Ginseng

利用4株木霉通过对峙法分别对人参疫病菌、西洋参锈腐病菌进行了体外拮抗作用的测定和评价。结果表明:4株木霉对人参疫霉菌、西洋参锈腐病菌均有一定程度的抑制作用,其中30371、30048、30153、30167对人参疫霉菌抑制率分别为70.45%、62.05%、47.39%、44.32%;30153、30048、30167、30371对西洋参锈腐病菌抑制率分别为55.00%、53.41%、52.73%、48.30%。

Tr/choderma 30371,30048,30153 and 30167 in dual culture with the pathogens of blight of Panax ginseng and root rust rot of American ginseng were studied. Results： A range of antibiotics was produced by Trichoderma 30371,30048,30153,30167 which were active against the hyphal growth of American ginseng rust rot and Panax ginseng blight. The inhibition ratio of Trichoderma 30371,30048,30153,30167 to Panax ginseng blight were70.45%,62.05% ,47.39%,44.32% respectively, The inhibition ratio of Tri- choderma 30153,30048,30167,30371 to root rust rot of American ginseng were 55.00%,53.41%,52.73%,48.3% respectiv.ely.
