당근종자 발아촉진에 관한 연구 (제2보) 당그종자 발아에 미치는 X-ray, Ultraviolet Light의 영향
Studies on the Acceleration of Germination in Carrot Seed (II) Effects of X-ray and Ultraviolet light in the Germination of Carrot Seed
초록
The treatment of X-ray was manipulated with the large focus of X-ray which was produced the capacity of 90 kilovoltage and 30 milliamphere in the distance of 50 centimeter. The germination of each gruop irradiated with X-ray for 5, 6, and 7 seconds was more delayed in the growth of carrot seed than those of the control group. However the germination of each group irradiated with X-ray for 2, 3, and 4 seconds was rather accelerated than those of the control group. The irradiation of ultraviolet light was carried out in the distance of 20 centimeter by Toshiba germidicial lamp which appeared the wavelength of 2537A
