查询词典 Eriocaulaceae

In this study, 6 species from Eriocaulaceae, Xyridaceae, Commelinaceae, Juncaceae were collected as material.

本试验以谷精草科，鸭跖草科，黄眼草科和灯心草科为研究对象。

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.

从构建的系统发育树可以得到：①谷精草科独立形成一个植物类群，支持谷精草科独立成为谷精草目；②谷精草科与鸭跖草科聚成一个大的类群，说明两科的亲缘关系较近，并且表现为平行进化；③灯心草科不近缘于谷精草科，与禾本科相比，灯芯草科与莎草科之间存在更近的亲缘关系；④在进化程度上，灯心草科比谷精草科原始；禾本科与谷精草科的亲缘关系最远，并且在这几个科中处于最原始的进化地位；⑤系统树还支持谷精草科内部的系统关系，支持谷精草属在谷精草科中的原始系统位置。

And its also difficult to ensure the relationship between Eriocaulaceae and the relatived families.

因此，谷精草科在单子叶植物中的系统位置，以及与其它相关科的关系一直不太明确。

While sometimes,the study about Eriocaulaceae based on molecule didnt consistent with those of classical taxonomy.

但是关于谷精草科的分子系统学研究的结果往往与经典的形态学研究不一致。

Type genus of the Eriocaulaceae: rushlike aquatic or marginal perennials usually found in shallow waters of ''.

谷精草''。'科'。''的模式属；水生或边缘一个多年生植物属，像灯芯草的，常生长于''。

Fininally, combining to the morphological characters , the taxonomy of Eriocaulaceae and the relationship among these families were studied,which could prove the existing result both from morphological and molecular characters.

并结合形态学研究探讨谷精草科的系统位置，以及与其它几个科的关系，进一步验证已有的形态学和分子系统学的研究结果。

Type genus of the Eriocaulaceae: rushlike aquatic or marginal perennials usually found in shallow waters of acid lakes and pools and bogs.

谷精草科的模式属；水生或边缘一个多年生植物属，像灯芯草的，常生长于酸水湖水池及沼泽的浅水处。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
