摘要： 3毫克/升的多效唑(MET)和8%蔗糖相结合的壮苗培养基,在22℃条件下培养30天,无根冬小麦花粉植株单株生根平均可达7.5条,平均根长为2.7厘米,生根率为89.4%.在越夏过程中培养基含有多效唑时,对花粉植株有明显的抑制发育、抑制株高生长和促进试管花粉植株增加分蘖的作用.移栽后30天调查,成活率达95.2%,与壮苗培养基中不含多效唑的对照相比提高29.7%.

Abstract: On the medium of headening plantlets containing 3 mg/1 MET(multi-effect triazole)and 8%sucrose and under 22? for 30 days, a rootless plantlet of wheat anther regenerated 7.5 roots on an average, the root length was 2.7 cm, and the rooting frequency of the plantlets was 89.4%.In the course of summering, MET in the medium pleyed an abvious role in restraining development and growth of the anther plants and increasing the tiller number for plantlets. After 30 days of transplanting,survival rate of anther plants could be 95.2% and increased 29.7%compared with that in medium without MET.
