Abstract

Fusarium oxysporium f. sp. cubense (Foc) race is an archetypally soil-born fungus causing chief fiscal damage to farmers growing banana plants. Supervising Foc is attained by the habit of chemical fungicides which undesirably harm the soil fertility. Our investigations intended to activate the aptitude of Trichoderma strains for activation of PGPR and IIR. The activation and accretion of defence enzymes such as Polyphenol Oxidase (PPO), Phenylalanine Ammonia-Lyase (PAL) and Peroxidase (PO) are been amplified by inoculation, and treatment with a combination of Trichoderma harzanium and Trichoderma viride strains (T3-H1+V1). Besides combination-based inoculum treatments gave best results than individual and fungicide-treated plantlets for supervising Foc pathogenesis. Based on the results we conclude that usage of T1-H1 and T2-H2 treatments with a combination such as T3-H1+V1 gave promising results and can be used as a prominent biocontrol formulation for inducing defence enzymes and PGPR in Musa paradisica cv. Malnad Rasbale.

木霉干预天堂木菇防御酶的激活。Malnad Rasbale植物

古巴尖孢镰刀菌(Fusarium oxysporium f. sp. cubense, Foc)是一种典型的土生真菌，对种植香蕉的农民造成主要经济损失。监测Foc是通过化学杀菌剂的习惯来实现的，而化学杀菌剂会对土壤肥力造成不良影响。我们的研究旨在激活木霉菌株激活PGPR和IIR的能力。接种哈扎木霉和绿木霉(T3-H1+V1)组合处理可增强多酚氧化酶(PPO)、苯丙氨酸解氨酶(PAL)和过氧化物酶(PO)等防御酶的激活和增加。此外，联合接种对Foc发病机制的监测效果优于单独接种和杀菌剂接种。综上所述，T1-H1和T2-H2处理与T3-H1+V1组合使用具有良好的效果，可以作为诱导天堂菇防御酶和PGPR的重要生物防治配方。Malnad Rasbale。
