Abstract

A study on the effect of gamma radiation on groundnut (Arachis hypogea) and Chili (Capsicum annuwn) was conducted at Universiti Putra Malaysia Bintulu Campus. The variety used for groundnut was 'Karisma Sweet' while that of chili was 'Kulai'. All the seeds were irradiated by MINT (Malaysian Institute of Nuclear Technology). The gamma-radiation doses used were 50, 100, 150, 200 and 250 Gy for groundnut and 300, 400, 500, 600 and 800 Gy for chili. The seeds were germinated at the Horticulture Unit, UPMKB in sand beds. The effects of gamma-radiation at several doses on the groundnut and chili germination, height, survival, root length and dry weight were identified. The chili germination and survival percentage decreased with increasing gamma-radiation. The height of groundnut and chili plant, root length and dry weight of chili also decreased with increasing dosage. The LD50 for chili was estimated at 445 Gy while the highest dose (250 Gy) applied to the groundnut did not reach the LDso.
