Response of metabolites of Alternaria solani on seed germination seedling vigour of Solanum nigrum L.
Keywords:
Fungal metabolite, Solanum nigrum L, Alternaria solani, mutagenicAbstract
Fungal microbes secrete secondary metabolites in infested host tissues are known to create disturbances in the normal cell metabolism and cell division of somatic cells causing cytological abnormalities. The toxic metabolites obtained in nutrient medium at different growth intervals by Alternaria solani (Ellis & Martin) Jones & Grout were isolated from culture medium and tested for their cytological effects on somatic cells of the test material. An increase in per cent seed germination and seedling emergence without any abnormalities were recorded with seven days old metabolites treated seeds. The seed germination rate and seedling growth decreased while percent abnormalities increased with metabolites of longer duration. Many abnormalities such as anaphase bridge, laggards, diagonal metaphase and mis-orientation of mitotic spindles were observed in treated seeds.
