- 摘要:
- 以20个不同居群的半夏为试材,采用根尖细胞压片方法,研究了半夏染色体对半夏细胞的地理分布及起源的影响。结果表明:半夏的染色体数目具多样性,倍性具多样化,半夏的多样化分化中心在横断山脉和华北平原2个地区,在地域分布上有由贵州地区向西南、东北和西北方向扩散的趋势。新发现染色体数2n=86,同时发现半夏染色体的非整倍体(90、92、96、116)比例占72.2%。
- Abstract:
- In order to analyze the chromosomes of geographical distribution in Pinellia ternate,20 different populations of Pinellia ternate were used as materials,by the way of root tip cells tabletting method.The results showed that the chromosomes and the ploidies were diversity in Pinellia ternate.Its distribution had a tendency to increasing from Guizhou to southwest,northeast and northwest.It was found that the new chromosome number was 2n=86.The heteroploid(90,92,96,116) rate was reached 72.2%.
