查询词典 phenetic

All evidences from both phenetic classification and cladistic classification demonstrated that the matsutake group is a polyphyletic group and Tricholoma nauseosum, T. matsutake and T. matsutake var. formosa come from one line of descent; T. focale, T. robustum and T. fulvocastaneum are closely related; T. zelleri, T. aurantium, T. caligatum var. nardosmia formed a clade. The result also suggested Dollo parsimony criterion was more suitable for phylogenetic reconstruction of the matsutake group based on morphological characters than the other two criterions.

在数量分类学研究中，通过表征分类和支序分类的研究得出结论如下：松口蘑群是一个多系群，北欧口蘑、松口蘑(T.matsutake)和松口蘑台湾变种(T.matsutake var.formosana)比较接近，羽衣口蘑、粗壮口蘑和黄褐口蘑(T.fulvocastaneum)也比较接近，泽氏口蘑、金黄口蘑(T.aurantium)和欧洲口蘑松香味变种(T.caligatum var.nardosmia)来自一个谱系。

Taxonomic species are defined on phenetic discontinuities, not on interfertility

分类学上的种是根据表型不连续性而不是根据互交可孕性来确定的。

The morphological characters of all taxa in the matsutake group were analysed under phenetic classification and cladistic classifi...

The morphological characters of all taxa in the matsutake group were analysed under phenetic classification and cladistic classification which contains Fitch, Wagner and Dollo parsimony criterions.

本文由松口蘑群的形态学数量分类研究、分子系统学研究、生物地理学研究和单种描述四个部分组成。

The journal well informs the research advances of this field, including phylogeny, phenetic studies, leaf anatomy, seed development, integrated molecular and morphological study, cytogenetic studies and structural and functional studies etc.

该杂志全面提供了该领域的研究进展，包括发展史、表现型分类法研究、叶类解剖、种子发育、整体分子与形态学研究、细胞发生研究以及结构与功能研究等等。

The content of assemble alkaloids of huperzine in 10 different geographical populations of Huperzia serrata and Phlegmariurus cryptomerianus from Zhejiang and Fujian Province was determined,and their phenetic differentiation in chemical composition was studied using the method of dedentred correspondence analysis based on their UV spectra.

对来自浙江、福建境内石杉科植物蛇足石杉、柳叶马尾杉10个不同地理居群的石杉总碱含量进行了测定，并基于紫外光谱，对它们的表型分化进行了除趋势对应分析。

The phenetic characteristics including Gram stain, catalase test, the adaptation to different stress conditions and producing acid from carbohydrates were tested.

结果表明，分离菌株N7-03具有较强的苹果酸-乳酸酶活力[117.05mg苹果酸/log]，进一步的研究表明，N7-03具有良好的酿造学适应性。2。

Phylogenetic subtrees for subfamily containing core diether lipids of C20-C25 were produced by the alignment of the 16S rRNA sequences of the two strains with those of other halobacteria, polar lipid compositions were analyzed, and some phenetic properties were determined.

二株嗜盐嗜碱古生菌（A33和GA33）的16S rRNA序列已经测定，以16S rRNA序列为基础的系统发育树通过于其它嗜盐古生菌成员16S rRNA序列的多序列匹配排列而建立。

Results show that molecularsystematics study can supplement the shortcoming of morphological study onspecies delimitation of Bothriocephalid tapeworms since molecular evolutioncan reflect the intrinsic phylogenetic relationships among species,and sincethe phenetic evolution and molecular evolution are independent processes,with the former reveals more conservative change than the latter.

结果表明形态学研究对于头槽绦虫种的界定存在明显不足，而分子系统学研究可以弥补这个不足；两者在进化上位于不同层次，前者进化速率非常缓慢，相对而言后者更能反映物种间遗传本质上的亲缘关系。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
