石莼属 meaning in Chinese

green laver
sea lettuce

The results suggest : dna samples that were extracted using the modified ctab method were successfully amplified by rapd ; rapd technique showed some potential to be useful in determining relationship between species within the two genera . the taxonomic position of ? linza , which is problematic based in morphological classification , showed a closer relationship with ulva
结果表明，应用改进的ctab法获得的dna样品可成功用于rapd扩增； rapd技术适用于这两个属种间关系鉴定；基于形态分类有争议的缘管浒苔的分类地位在rapd分析中表现出与石莼属更近的亲缘关系。
Sixties primers were used for dna amplification and a total of 237 amplification products range from 450bp to 2500bp were generated . a similarity matrix for all pairwise comparisons was calculated using nei and li ' s formula and then transformed to distance matrix . dendrograms were constructed by applying unweighted pair - group arithmetic average ( upgma ) and neighboring - jointing cluster analyses using the phylip software
在第二部分，应用改进的ctab法提取了石莼属和浒苔属各3个种及作为对照的刚毛藻的基因组dna ， 60个引物被用于扩增，共获得237个片段大小在450 - 2500bp之间的扩增片段，依据nei和li ( 1979 )的公式计算出样品成对比较的相似性距阵并换算成遗传距离，应用phylip软件包，按照upgma法和n - j法分别构建聚类图。
