摘　　要：以"红牡丹"、"富哥尔一号"2个杜鹃品种为试材,研究了不同剂量的60Co-γ射线对2个杜鹃品种成熟植株的芽成活率、新梢长度、新叶长宽、开花和花特性的影响。结果表明:在25~65Gy剂量范围内,供试植株芽成活率、新梢长度、新叶长宽等均随剂量的加大而下降,花期推迟,花量减少,但花的变异度增加,表现出花色和花瓣形态的多样性;表明2个品种的杜鹃耐辐照能力稍有差异。The mature plants of two azalea varieties,including ＇Red Peony＇,＇ Fugeer No. 1＇ were irradiated by ^60Co-γ rays at different doses,and the irradiation effect of the survival rate of buds, new shoot length, new leaf length and width, blossom and flower traits were observed. The results showed that the survival rate of buds, new shoot length, new leaf length and width of irradiated plants decreased as the doses increased within the range 25 Gy to 65 Gy, while the florescence delayed,the number of flower petals reduced,the flowers＇ degree of variation, flower colours and petal types increased. Irradiation endurance of the two varieties was a little different.
