- 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。
- 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 temperaturetreatment;no roo t seedling could be controlled at 3% and weak seedling could be contro lled at 5% with 1/2MSsubstitute MS medium and day light 12 hours .
