Incidence of seed borne mycoflora of brinjal when stored at different temperatures

Abstract

Brinjal seeds with 12% moisture content were stored at room temperature for nine months at 5, 15, 25 and 350C. The observations were recorded after three months interval on incidence of seed borne mycoflora and seed quality parameters. The maximum percent incidence of Alternaria alternata, Aspergillus flavus, Curvularia lunata, Aspergillus niger, and Rhizopus stolonifer (5.60, 41.60, 16.00, 12.80 and 36.80 respectively) were recorded after nine month of storage. The highest prevalence of fungi in brinjal was recorded in seeds stored at 350C and least in 50C. Decreased of percent seed borne fungi were observed with increased of storage period at cold temperature storage condition. The maximum germinabilty and vigour index were 94.40% and 1107.50 respectively after one month of storage and the minimum were 43.20 and 262.69 after nine months of storage at 350C. Germination and vigour index of seeds were decreased with increased of storage time and fungal infection.
