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花粉植株的自然加倍率;用1/2 MS培养基取代MS培养基、并控制每日光照12h,可将无根苗控制在3%以下,弱苗控制在5%以下。

Abstract: Strengthening seedling and doubling chromosome of pollen plant of spring wheat have been studied in this paper. . The result show that: natural doubling rate of pollen plant of spring wheat can be increased quickly by prolong low temperature treatment; no root seedling can be controlled at 3% and weak seedling can be controlled at 5% with 1/2MS substitute MS medium and day light 12 hours.
