摘要
以我国北方的主要牧草苜蓿、沙打旺、草木樨、三叶草、小冠花、燕麦草等９６个品种为材料，用６０Ｃｏ－γ射线照射干种子，研究其辐射敏感性及适宜剂量。结果表明，出苗率随照射剂量的增加而降低，它们之间呈负相关；依据半致死剂量，将牧草划分为辐射敏感型。
adiation-sensitivity and optimum dosage for 96 forage species were studied by using 60 Co-γ Ridiation rays to irradiate dry seeds which included lucerne, milkvetch, sweet, clover, coronilla, oat etc. The results showed that the rate of seeding emergence decreased along with the radiation dosage increasing, and there existed negative interration between them. The forages are classified according to their radiation-sensitivities.
