EFFECTS OF SEED BORNE MYCOFLORA ON SUGAR, OIL AND FATTY ACID COMPOSITION OF THREE VARIETIES OF MUSTARD (BRASSICA COMPESTRIS) VIZ,BASANTI, KALASONA, KAVERI AK-47.

Abstract

The present study was conducted to explore the seed born mycoflora or fungi associated with seeds of mustard. A total 7 fungi were isolated among the isolated fungi in all replications. Aspergillus flavus was most dominant species, so further investigated were carried out with Aspergillus flavus. Mass multiplication of the pathogen was done and Aspergillus flavus was cultured on PDA plates. The spores were collected after 5 days and a spore suspension was prepared. The culture filtrate was used to infest the healthy seeds of mustard varieties Basanti, Kalasona, Kaveri AK-47. After infestation for 48 hours the studies were conducted to check the impact of Aspergillus flavus on the biochemical parameters as well as Vigour of the seed. The oil content of both the samples (healthy and infested) was studied for all three varieties, colour, odour and quantity of oil was taken into consideration. There was reduction in oil quantity, color and odour in case of infested seeds as compared to healthy seeds.
