摘　　要：以大白菜—结球甘蓝系列单体异附加系试管苗为试材,比较了不同单体异附加系试管苗的生根率和移栽成活率,研究了不同浓度NAA对单体异附加系试管苗生根和根尖细胞分裂的影响。结果表明:AA+C1、AA+C2、AA+C3、AA+C4、AA+C5和AA+C6的试管苗生根较好,移栽成活率高,AA+C7、AA+C8和AA+C9的试管苗不易生根,移栽成活率低;1/2MS培养基附加1.5mg.mL-1NAA能有效诱导试管苗生根,提高试管苗生根质量和移栽成活率。With the plantlets of Chinese cabbage〔Brassica compestris L.ssp.pekinensis(Lour)Olsson〕-cabbage(Brassica oleracea L.var.capitata L.)monosomic alien addition lines as materials,comparison of rooting rate and transplanting survival rate among different monosomic alien addition lines and effect of NAA content in 1/2 MS medium on the root induction were conducted in this paper.The result showed that monosomic alien addition lines AA+C1,AA+C2,AA+C3,AA+C4,AA+C5,and AA+C6 had higher rooting and transplanting survi...
