木霉因其对植物生长的促进作用（如增强营养供应、抑制植物病原体和促进植物防御）而对环境至关重要。生物源挥发性有机化合物（VOCs）是木霉菌产生的多种化学物质。VOCs在生物控制和植物生长促进中的潜在作用最近已被认识到。在这里，木霉-挥发性有机化合物的植物生长促进和抑制植物病原体的性能进行了评估。进一步研究了T.用GC-MS对哈茨木属植物进行了鉴定。木霉属-VOC对所有测试的病原真菌表现出显著（p < 0.05）的抗真菌特性。T.脱毒-VOC显示出对Alternaria panax、Botrytis cinerea、Drocarpon destructans和Sclerotinia nivalis的决定性抑制。萌发的种子表现出的木霉挥发性有机化合物的存在下，由不同的菌株排放的生长增强。低水平的环戊硅氧烷，十甲基，环四硅氧烷，和八甲基在T。而环戊硅氧烷、十甲基、环四硅氧烷和八甲基作为含Si化合物显示出更高的发射水平。这些结果揭示了VOCs作为有害根际微生物生物控制资源的潜力，并强调了木霉VOCs排放在调节植物生长发育中的重要性。
Trichoderma is environmentally vital due to their plant growth-promoting effects (such as enhancement of nutrients supply, suppression of plant pathogens, and promotion of plant defense). Biogenic volatile organic compounds (VOCs) are diverse chemical substances emitted by Trichoderma spp. The potential role of VOCs in biological control and plant growth promotion has recently been recognized. Here, the Trichoderma-VOCs' performance for plant growth promotion and suppression of plant pathogens are evaluated. We further investigated VOC emission profiles of T. harzianum using GC–MS. The Trichoderma-VOCs exhibited significant (p < 0.05) antifungal properties against all tested pathogenic fungi. T. atroviride-VOCs showed a decisive inhibition of Alternaria panax, Botrytis cinerea, Cylindrocarpon destructans, and Sclerotinia nivalis. The germinating seeds demonstrated growth enhancement in the presence of Trichoderma-VOCs emitted by different strains. Low levels of cyclopentasiloxane, decamethyl, cyclotetrasiloxane, and octamethyl were found in T. harzianum KNU1 strain whereas cyclopentasiloxane, decamethyl, cyclotetrasiloxane, and octamethyl showed higher emission levels as Si-containing compounds. The results reveal the potentiality of VOCs as a biocontrol resource against deleterious rhizosphere microorganisms and underline the importance of Trichoderma-VOCs emissions in regulating plant growth and development.
