저선량 감마선이 땅콩 생장에 미치는 효과 = Effect of Low Dose of Gamma Radiation on the Growth of Groundnut ( Arachis hypogaea L. )

다국어 초록 (Multilingual Abstract)

Effect of low dose gamma radiation on the growth of groundnut (Arachis hypogaea L.) were investigated with respect to germination rate, seedling development and yield. Seeds of “Palpal”cultivar were irradiated with 0.5∼20 Gy of γradiation in order to determine the hormetic effect of low dose radiation. The germination rate of γ-ray irradiation group was lower than that of the control but the seedling height of groundnut grown from seeds irradiated with low dose γ-ray was slightly higher than that of the control. The number of pod and kernels, and the seed yield increased by 27%, 17% and 19%, respectively, in the 12.0 Gy irradiation group compared to that in the control group. The 100 seed weight was 87.2g in the 4.0 Gy irradiation group, which was 11% heavier than 78.3g in the control group. Low dose radiation showed an enhancement effects on the growth and yield components of groundnut. [radiation hormesis, gamma radiation, groundnut, germination rate, yield].
