RELATIONSHIP BETWEEN ESSENTIAL OIL TREATMENT ON SEED MYCOFLORA AND SEEDLING QUALITY OF SOME OIL SEED CROP SPECIESG. THIPPESWAMY, S. LOKESH AND V. RAVISHANKAR RAIAbstract Seeds of Sesame, Groundnut, Castor and Niger were subjected to essential oil treatment showed maximum reduction in the incidence of mycoflora. Fusarium semitectum and Fusarium solani exhibited more sensitivity to essential oils than that of FilSari11111 moniliforme. Irrespective of the treatment Penicillia and saprophytic species were drastically reduced. Cinnamon oil expressed strong inhibitory effect against Macrophomina phaseolina. In Castor all the essential oils inhibited the colonization of Alternaria ricini and Fusariurn oxysporunt, where as in Groundnut the treatments resulted in minimization of Sclerotium rolfsii. Essential oil treatment also stimulated the germination and seedling growth over control. In Sesame clove oil enhanced the germination to a greater extent. In Groundnut cinnamon and clove oil treatment resulted in the heavy foliation and early flowering. Essential oil treatment irrespective of its type and the crop species improved the root and shoot length and vigour of the seedlings.
