Abstract

Influence of an endomycorrhizal species Glomus fasciculatum on the growth of two vegetable plants, namely, Solanum melongena and Lycopersicon esculentum and for reduction of the incidence of fusarial wilt disease under field condition was studied. VAM treated plants showed more vigor in terms of productivity parameters viz., plant height, number of branching twigs and fruit production. VAM and pathogen treated plants also showed positive effect of VAM-symbiont over control indicating reduction of pathogenic stress of the plant and give resistance. Leaf phosphate, chlorophyll content and percentage of mycorrhization were recorded highest when plants were singly inoculated with Glomus fasciculatum . Synergistic effect of VAM and pathogen to increase on productivity vis-à-vis resistance was also studied in respect of polyphenol oxidase. The experimental findings indicated the potential use of G. fasciculatum for improving the growth and imparting resistance of brinjal and tomato.
