【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。更多还原

【Abstract】 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.更多还原
