Abstract:: 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.
