EFFECT OF POLYALTHIA LONGIFOLIA (SONNER) THW. ON SEED MYCOFLORA, SEED GERMINATION AND VIGOUR INDEX OF GROUNDNUT CV. TLG-45

The present study was carried out to investigate the effect of leaf extract of Polyalthia longifolia (Sonner) Thw. on seed mycoflora, seed germination and successive seedling vigour of Groundnut Cv. TLG-45, was tested by using standard blotter method (De Tempe (1953). Plants make many biopesticides that have biological functions, including defense against external and internal seed-borne fungi. The root and shoot length, percentage germination of seeds and seed vigor index was found to be more in case of Polyalthia longifolia. The effect of plant extract on decrease seed mycoflora and increase seed germination and vigour index of Groundnut Cv. TLG-45 was observed.
