작물 초기생육에 대한 저선량 방사선의 효과를 보고자 벼, 콩, 들깨 종자에 저선량 $^{\gamma}$선을 조사하여 발아율과 초기 생육을 관찰하였다. 저선량 $^{\gamma}$선에 의한 작물의 생육초기 효과는 한정되었으나 작물과 생육특성에 따라 적정 선량은 다르게 나타났다. 벼종자의 발아율은 2Gy조사구에서, 유묘초장과 생체중은 0.5Gy에서 가장 높았으며,대두종자의 발아율과 유모생육은 4Gy에서 가장 양호하였다. 들깨종자의 저선량 $^{\gamma}$선 조사에 의해 생육이 다소 불량하였으나 발아율은 2Gy에서, 유묘초장과 생체중은 1Gy에서 증가효과를 나타내었다.

Germination rate and early growth in crop such as rice,soybean,and perilla were observed after irradiation of $^{\gamma}$-ray (Co-60) in order to determine the effects of low does radiation. The low dose radiation was able to improve the early growth in crops and their agricultural charaters. Germination rate of 2Gy-irradiatied rice seeds was high and also were seeding height and fresh weight of the 0.5 Gy-irradiated. Germination rate and early growth of soybean were high in 4Gy-irradiated group. Perilla gew ot so promisingly after after low dose irradiation,however there slightly increasing effects on germination rate, seeding height and fresh weightat 2Gt-, 1Gy-, and 1Gy irradiated group, respectively.
