五福花科花部维管结构的比较研究

首次报道了华福花属华福花Ｓｉｎａｄｏｘａｃｏｒｙｄａｌｉｆｏｌｉａ和东方五福花Ａｄｏｘａｏｒｉｅｎｔａｌｉｓ花部维管结构，并对五福花科３属４种植物的花部维管系统进行了比较研究。３属４种的花部维管系统表现出不同的对称性和不同的复化、减化以及不同的融合程度。基于花部维管系统的证据，本工作支持四福花属四福花Ｔｅｔｒａｄｏｘａｏｍｅｉｅｎｓｉｓ为科内原始类群代表的看法。

A COMPARATIVE STUDY OF THE FLORAL VASCULATURE IN ADOXACEAE

The floral vascular systems are compared among all four species of three genera in Adoxaceae, including Sinadoxa corydalifolia, Adoxa orientalis which have not been studied previously. The vascular systems of these 4 species manifest different symmerry, and different degrees of multiplication, reduction and fusion. On the base of the evidence of floral vasculature, it can be presumed that Tetradoxa omeiensis seems to be the most primitive taxa in Adoxaceae.
