Effect of Pathogenic Seed Mycoflora of Ajwain ( trachyspermum Ammi l.) on Volatile Oil Content of Seeds

The estimation of deteriorative effect of seed mycoflora on volatile oil contents of ajwain seeds, samples collected at post-storage (just before next sowing) stage were isolated using blotter and agar plate methods. Two separate inoculations were made with seven different mycoflora and seed inoculated with Drechslera australiensis showed increase in per cent volatile oil content. Seed inoculated with rest of the fungi viz., Aspergillus flavus , Aspergillus niger , Aspergillus ochraceous , Drechslera australiensis , Fusarium sporotrichioides , Rhizopus oryzae and Trichoderma viride showed reverse/equal in per cent volatile oil contents of seeds.
