Abstract

The mycorrhiza plant partnership is the basic, essential and integral part of plant survival and growth. In the present investigation we are reporting the effect of culture filtrate of Piriformospora indica, a growth promoter and bioprotector fungus on Aristolochia elegans Mart. The culture filtrate of the fungus increased overall growth, biomass, and active ingredient-aristolochic acid in the leaves of plants. In untreated control plants, the overall growth was reduced. P. indica culture filtrate application increased root number, root length, and root dry weightby 28%, 98%, and 123% respectivelyin plants of Aristolochia. Also stem height and shoot length was enhanced by 43% and 155% respectively.There was increase in number of leaves by 79% and length of leaves by 36%. The increase in total biomass was 136%. The improvement in content of aristolochic acid in leaves was between7.6% and 28.8%in treated plants as against untreated control plants
