ARBUSCULAR MYCORRHIZAL FUNGAL-ASSOCIATED BACTERIA AFFECT MYCORRHIZAL COLONIZATION, ESSENTIAL OIL AND PLANT GROWTH OF Murraya koenigii L.

Abstract

Murraya koenigii L. (family: Rutaceae) commonly called as curry leaf is a highly valued plant for aroma and medicinal value. The two dominant AM species Glomus mosseae and Acaulospora laevis were isolated from the rhizospheric soil of M. koenigii. A pot experiment was performed to see the interactive potential of G. mosseae and A. laevis alone or in combination with Pseudomonas fluorescens on M. koenigii. Various morphological and biochemical parameters were measured after 120 days. Overall results suggest that although, all co-inoculation treatments showed beneficial effects on all the growth, physiological and oil content. The overall results demonstrate that the co-inoculation of bioinoculants like P. fluorescens with AM fungi promotes higher AM colonization and spore number enhancing nutrient acquisition especially phosphorus (P), improving the rhizospheric condition of soil.
