木霉生防菌对植物生长的影响

 自木霉(Trichoderma)被发现具有生防价值以后,对其重寄生作用和拮抗成分的分析投入了大量的研究。而对植物生长的影响却被忽略了。象根瘤菌(rhizobia)和菌根真菌(mycorrhizae)一样,木霉能够对植物的生长产生明显的影响。它能产生植物毒性成分而抑制植物生长,也能通过产生激素和根际竞争能力促进植物生长,特别是它能诱导植物产生抗性。因此,仅对其抑制病原菌的能力进行讨论是不足够的。木霉在促进植物生长和诱导植物产生抗性具有真正的潜能。

Effects of Biocontrol Agent Trichoderma on Plant

Since Trichoderma had been found had potential for biological control,its ability of mycoparasitism and the production of antimicrobial compounds have been studied extensively. But its effect on plants was underestimated. Like rhizobia and mycorrhizae, Trichoderma have great effect on plants. Trichoderma spp. can produce phytoxic compounds resist plant growth. At the same time, some isolates have been acclaimed that they can stimulate plant growth through rhizosphere compentence, and also can induce resistance reactions in plant. So, it is not sufficient to simply evaluate Trichoderma result from its capacity suppress pathogens. Trichoderma has real potential for plant growth promotion and induced resistence.
