摘要
对灰霉菌(Botrytis cinerea)和木霉菌BTW41(Trichoderma atroviride)之间相互关系作了初步研究。研究发现木霉菌具有较强的营养竞争能力,BTW41与灰霉菌的对峙菌落接触处,可见灰霉菌菌丝被木霉菌菌丝大量寄生,受到严重破坏,并且灰霉菌菌丝有消解现象。不同木霉菌株对番茄灰霉病的防效不同,BTW41的防效能够达到60.99%。施入叶片上的生防木霉菌孢子应达到一定浓度才会有效地定殖,进而起生防作用,灰霉菌对木霉菌在番茄叶片上定殖有影响。从以往所做的试验来看,木霉菌孢子浓度在108个孢子/mL以上时,对灰霉病的防效较好。
The interaction of botrytis cinerea and trichoderma was studied in detail in this article. The results showed that trichoderma had stronger competition ability, and the hyphae of botrytis were destroyed seriously by trichoderma on microscopic section via parasitism. Different trichoderma culture had different control effects, the control effect of BTW41 could be up to 60.99%. The colonization was successful when spore density of trichoderma was adaptive, and the colonizing could be influenced by botrytis cinerea. In accordance with the results previously, the control effect to Botrytis cinerea was better when the spore density of trichoderma was more than 10^8 unit/mL.
