This study reports the effects of seed treatment with Cordyceps fumosorosea on seed germination, growth, colonization of eggplant (Solanum melongena), and growth of Bemisia tabaci (feeding on fungal colonized eggplant leaves). Germination rates of eggplant seeds were similar among different treatments. The growth parameters such as root length, shoot length, and number of leaves) differed significantly after 15, 30, and 60 days of seed treatment. The total dry weight of eggplant in response to treatment with C. fumosorosea isolates increased significantly when compared with the control. Both isolates of C. fumosorosea colonized different plant tissues, although the extent of colonization decreased during the experimental period. The colonization of eggplants by both C. fumosorosea isolates resulted in a significant reduction of B. tabaci incidence. This study possibly provides the first report of increased plant growth and increased insect mortality in eggplants inoculated with C. fumosorosea isolates.
本研究报告了用玫烟色棒束孢进行种子处理对茄子(茄属)种子萌发、生长、定殖以及烟粉虱(取食被真菌定殖的茄子叶片)生长的影响。不同处理间茄子种子的萌发率相似。种子处理15、30和60天后,根长、茎长和叶片数量等生长参数存在显著差异。与对照相比,用玫烟色棒束孢分离株处理后茄子的总干重显著增加。两种玫烟色棒束孢分离株均定殖于不同的植物组织,尽管在实验期间定殖程度有所下降。两种玫烟色棒束孢分离株对茄子的定殖均导致烟粉虱发生率显著降低。本研究可能首次报道了接种玫烟色棒束孢分离株的茄子生长增加和昆虫死亡率增加的情况。
