Abstract:
A study was conducted at the Department of Plant Pathology, N. M. College of Agriculture, NAU, Navsari during 2021-22 to find out the effect of fungal metabolites of Alternaria alternata on seed germination and seedling vigour index of coriander. Fungal metabolites become more toxic as they age and concentration increases. In both 7 days after seed germination and 14 days after seed germination, 50-day-old fungal metabolites were highly toxic and caused a maximum reduction in seed germination, seedling growth (radicle and plumule length) and vigour index over control. At cent percent fungal metabolites concentrations, the highest reduction in germination percent, seedling growth (radicals and plumules) and vigour index is observed.
