Studies on Influence of Arbuscular Mycorrhiza and Some Plant Growth Promoting Rhizomicroorganisms on Rauvolfia Serpentina

Abstract

Rauvolfia serpentine (Linn.) Benth. ex Kurz (Indian serpentwood), belonging to the family Apocynaceae, and popularly known as India’s wonder drug plant. It is an upright, perennating, evergreen undershrub with tuberous roots. Its dried root is the economical part which contains anumber of alkaloids and some important secondary metabolites. The present study was conducted to determine the effect of arbuscular mycorrhizal fungi (Glomus fasciculatum) and some plant growth promoting rhizomicroorganisms (PGPR,s) on Rauvolfia serpentine plants under open pot conditions. Different plant growth parameters viz plant height, number of leaves, fresh weight, dry weight, mycorrhizal parameters were recorded. The results of this experiment clearly indicated that Glomus fasciculatum and plant growth promoting rhizomicroorganisms enhance the growth, biomass production in Rauvolfia serpentina plant. However future studies can be done for standardizing with different combinations of arbuscular mycorrhizae fungi and PGPR,s.
