摘　　要：用紫外光(UR)、红外光(FR)、混合光(RB)、红光(R)和兰光(B)分别以不同距离和不同时间对柠条锦鸡儿种子进行的照射表明,UR和R照射的出苗率最佳,分别比对照提高48.0％和42.67％;RB和R照射的幼苗生长最佳,B照射对种子出苗影响不大。The seeds of Korshinsk peashrub(Caragana korshinsku) were radiated respectively by ultraviolet ray (UR), infrared ray (FR),ray of blend (RB),red light (R) and blue light (B) under different distances, and the various indexes in seedling stage were observed. The data were analyzed by biological statistics. The results show that the seedling rates treated by UR and R were the best. Both them increase by 48.0% and 42. 67% compared with control (CK). RB and R were the best to seedling growth. B had little effects on seed.
