利用 Co~(60)对不同番茄品种干种子外照射,引起内部生理生化过程的变化,可取得增加产量、提早成熟、增强抗逆性的效果。我们对满山红、强力米寿、郑州4号、浙红20号,粤农2号、北京早熟等品种进行了处理,每个品种各取1克种子,一半照射,一半作对照。照射源是荆州地区农科所 Co~(60)丙种射线。方法是干种子外照射。满山红用1,500伦琴,2.5万伦琴、3.5万伦琴,其他品种用2万伦琴、3万伦琴。处理后的种子采用冷床薄膜覆盖,干籽直播营养钵育苗,每钵2—3粒。去年3月6日播种,4月10
Co ~ (60) could increase the yield, prematurely mature and enhance the resistance to stress by changing the internal physiological and biochemical processes of different tomato varieties exposed to dry seeds. We deal with varieties such as Manshanhong, Qiangli Mishou, Zhengzhou 4, Zhehong 20, Yuenong 2 and Beijing precociously. Each species took 1g of seeds, half of which was irradiated and half was used as control. The source of irradiation was Jingzhou Prefecture Agricultural Institute Co ~ (60) C rays. The method is dry seed external irradiation. Manshan red with 1,500 Roentgen, 25,000 Roentgen, 35,000 Roentgen, other species with 2 million Roentgen, 3 million Roentgen. Treated seeds covered with a cold bed film, seedlings dry seedling broadcast nutrition bowl, 2-3 per bowl. Sowed on March 6 last year, April 10
