摘　　要：对草地早熟禾的小矮人品种耐寒变异植株无性系的建立进行了研究,并成功地诱导出小矮人嫩叶的愈伤组织,分化出丛生不定芽。诱导愈伤组织的理想培养基是MS+BA 0.1mg/L+2,4-D 1 mg/L;由愈伤组织分化出苗的理想培养基是1/2 MS+BA 0.1 mg/L+2,4-D 0.1 mg/L;试管苗极易移栽成活,耐寒变异性状保持不变。The clone of cold resistant lawn plant-Poa pretensis was successfully established by inducing the callus and developing uncertain buds from its leaf.The best medium for callus induction was MS+BA 0.1mg/L+2,4-D 1 mg/L;medium consisting of 1/2 MS+BA 0.1 mg/L +2,4-D 0.1 mg/L was the best differentiation one for buds.Plantlets in tube were of the cold resistant character and with best rooting effect.
