分别利用5个不同剂量(109、145、195、284和560Gy)的高能混合粒子场和60Coγ射线处理龙牧803紫花苜蓿(Medicago sativa L.×Melilotoides ruthenicus (L.) Sojak cv. Longmu 803)干种子,比较同一剂量不同处理方法间和同一处理方法不同剂量间的生物学效应。结果表明,高能混合粒子场处理的种子发芽势和发芽率明显高于γ射线处理,发芽势高于对照,发芽率低于对照;微核率略低于γ射线处理,两者均显著高于对照;γ射线处理的株高和产量随着处理剂量的增高而降低,除109Gy外,均低于对照和高能混合粒子场处理,高能混合粒子场处理对植株的损伤效应较小。
Five different dosages (109, 145, 195, 284 and 560 Gy) of high-energy mixed particles and 60Co γ-rays were used to treat Medicago sativa L. × Melilotoides ruthenicus (L.) Sojak cv. Longmu 803 Seed, compare the same dose of different treatment methods and the same treatment method of biological effects between different doses. The results showed that seed germination energy and germination rate of high-energy mixed particle field treatment were significantly higher than those of γ-ray treatment, the germination potential was higher than that of the control, germination rate was lower than the control; micronucleus rate was slightly lower than γ-ray treatment, both were significantly higher Compared with control and high-energy mixed particle field, the plant height and yield of γ-ray treatment decreased with the increase of treatment dose except for 109Gy. The damage effect of high-energy mixed particle field on plants was less.
