望天树

望天树7个天然居群（194个个体）用20个随机引物进行了扩增，4822%的RAPD位点为多态位点，平均每个居群的多态位点百分比为2084%。

194 individuals in seven natural populations of P. chinensis were amplified with 20 random primers . 48.22 % of RAPD loci were polymorphic across the whole species , while only 20.84 % on average on population levels .

Study on fruiting behaviour , seedling establishment and population age classes of Parashorea chinensis

结果揭示了望天树低水平的遗传多样性和很强的地区居群分化，这可能是由于望天树在其进化历史上，居群不断的减小及再扩张所引起的居群瓶颈所造成的。

These results suggested low levels of genetic diversity in this species and strong regional population differentiation , which might be the results of population bottleneck resulting from the repeated extinction and recolonization in its evolutionary history .

运用水平切片淀粉凝胶电泳等位酶分析方法，对国家一级珍稀濒危保护植物望天树（Parashoreachinensis）进行了遗传多样性和居群分化的研究；

The genetic diversity and population differentiation of Parashorea chinensis , a rare and endangered dipterocarp , and listed in the Plant Red Book under Grade I , were examined using allozyme analysis of horizontal sliceable starch gel electrophoresis .
