摘要
对三株棉黄萎病菌的木霉生防菌的生物学特性研究表明 :其生长最适温度为 2 5～ 30℃ ;最适pH值为 4～5 ;最适光照条件为半黑暗半光照 ;孢子萌发对营养环境要求不严格 ,但在营养丰富的条件下萌发得更好。
Several basic bio-characteristics of 3 Trichoderma isolates which showed remarkable antagonistic effects to the pathogen of cotton Verticillium wilt were tested. The optimum temperature for colony growth and spore germination was 25 ℃～30℃, the optimum pH was 4～5 and the optimum light condition was semi-dark and semi-light. The nutrient conditions for spore germination were not strict, but it would have higher germination percentage if supplied with better nutrients.
