摘　　要：以结球芥菜种子为材料,研究了外源激素赤霉素(GA3)、萘乙酸(NAA)、6-苄氨基嘌呤(6-BA)和脱落酸(ABA)对芥菜种子萌发的影响。结果表明:除6-BA外,NAA、GA3和ABA均对芥菜种子的萌发产生影响。在50 mg/L浓度以上时,NAA可抑制芥菜种子的发芽指数和活力指数;GA3能提高芥菜种子的萌发特性,最佳处理浓度为50 mg/L;ABA能有效抑制芥菜种子的萌发,最佳有效抑制浓度均为150 mg/L。With seeds of Brassica juncea var. capitata Bailey used as experimental material, the study was focused on the effect of exogenous GA3 ,NAA,6-BA and ABA on the germination of mustard seeds. The results showed that the seed germination was significantly affected by GA3 ,NAA and ABA,but not hy 6-BA. Germination index and vigor index were restrained by 50 mg/L NAA. All characteristics of germination were promoted by 50 mg/L GA; ,restrained by 150 mg/L ABA.
