分别用109、145、195、284和560Gy5个剂量的60Coγ射线和高能混合粒子场处理龙牧803紫花苜蓿干种子,种植后田间观察,测定株高、鲜草产量和品质含量来比较2种不同诱变方法所造成的损伤效应。结果表明,高能混合粒子场处理过的植株在株高和产量上均高于同剂量γ射线处理的植株;而γ射线处理组的粗纤维含量普遍低于高能混合粒子场处理组,粗蛋白含量普遍高于高能混合粒子场处理组;粗脂肪含量在低剂量条件下(109、145和195Gy)γ射线处理高于高能混合粒子场处理,高剂量(284~560Gy)条件下则低于高能混合粒子场处理。
The effects of 60Co γ-ray and high-energy mixed particle fields with 109, 145, 195, 284 and 560 Gy doses on the dry seed of Longmu 803 alfalfa were observed, and field observations were made after planting, and the plant height, fresh grass yield and quality content The mutagenic effect of the damage caused by the method. The results showed that plants treated with high-energy mixed particle field were higher in plant height and yield than those treated with the same dose of γ-rays; however, the crude fiber content in γ-ray treatment group was generally lower than that in high energy mixed particle field treatment group, (109, 145 and 195Gy), the γ-ray treatment of crude fat was higher than that of high-energy mixed particle field, while the high-dose (284-560Gy) Particle field processing.
