摘　　要：用改良琼脂法,即0.2%秋水仙碱加1.0%琼脂溶胶对臭椿[Ailanthus altissima(Mill.)swingle.]进行24 h,48 h,72 h多倍体诱变,诱变率分别是61.90%,62.07%,46.88%.依据多倍体幼苗形态特征发现多倍体后代臭椿的生物学特征与对照相比有显著差异。By modified agar method,the induced polyploid breeding of Ailanthus altissima（Mill.） swingle was carried with adding 0.2% colchicine solution into 1.0% agar solution for 24 h,48 h,72 h,respectively,which induction rates were 61.90%,62.07%,46.88%.According to morphological characteristics of polyploid,the biology characteristics of induced mutation were significantly related with the control.
