摘　　要：研究了春小麦花粉植株的壮苗及染色体加倍技术。结果表明:延长低温处理时间可大幅度提高春小麦单倍体植株的自然加倍率;用1/2 MS培养基取代MS培养基、并控制每日光照12 h,弱苗控制在5%以下,可将无根苗控制在3%以下。Strengthening seedling and doubling chromosome of pollen plant of spring wheat have been studied in this paper. The result showed that：natural doubling rate of pollen plant of spring wheat could be increased quickly by prolong low temperature treatment;no root seedling could be controlled at 3% and weak seedling could be controlled at 5% with 1/2MS substitute MS medium and day light 12 hours.
