用60co-γ射线6000、8000、10000、12000、15000、20000伦琴辐照胜利1号、渭薯1号等四个品种块茎后,常温土窖贮藏,从10月份存放到翌年的8月份,辐照组不生根、不发芽,淀粉损失率为28.9—47.7％,薯块外表保持新鲜、饱满。特别在气温高、湿度大的6—8月份,块茎腐烂率仅为8.2—22.3％。而对照组,根、芽生长繁茂,淀粉损失率高达63.2—75.8％,薯块外形皱缩、凹陷,烂薯率12.8—24.6％。试验证明,用6000—15000伦琴辐照马铃薯常温贮藏,能有效地抑制马铃薯块茎的生根发芽。
Radiation with 60co-γ rays 6000, 8000, 10000, 12000, 15000, 20000 Roentgen radiated on the 1st, Ivory 1 and other four varieties of tubers, stored at room temperature in the pit, from October to the following year in August, the radiation As the group did not take root and did not germinate, the rate of starch loss was 28.9-47.7%. The appearance of potato block kept fresh and full. Especially in the high temperature and humidity in June-August, tuber rot rate was only 8.2-22.3%. In the control group, roots and shoots grew in a lush manner with a starch loss rate as high as 63.2-75.8%. Shoots were shrunk in shape, with a rate of 12.8-24.6%. Experiments show that 6000-15000 Roentgen irradiation of potato at room temperature storage, can effectively inhibit the root tuber of potato sprout.
