Abstract

Diverse group of micro-fungal organisms are proved to secrete or excrete both primary non- toxic as well as secondary toxic metabolites during growth and metabolism. Metabolites of primary origin induce growth stimulating response while secondary metabolites appear to create disturbances in normal cell metabolism, growth and reproduction. The metabolites produced in growth nutrient medium at different growth intervals by Alternaria alternata (Fr.) Keissler, a serious causal pathogen of leaf spot of Hordeum vulgare L, were isolated, confirm chemical nature and evaluated for their effect on seed germination, seedling emergence and fresh biomass production. An increase in per cent seed germination, seedling emergence and green biomass without any abnormalities over control were recorded with seven days old metabolites treated seeds while same parameters were declined with metabolites of longer duration. The metabolites responded uniformly in both the cultivars with the parameters undertaken. The U.V. absorption spectrum TLC and phytochemicals tests for isolated toxins confirmed phenolic in nature.

Keywords:Fungal metabolite, Hordeum vulgare L, Alternaria alternata, green biomass, vigour.
