摘要: 本文首次深入研究了伞形科参棕亚科和牵环花亚科及相关类群34属(参棕亚科9属,牵环花亚科21属)48种植物叶片(茎或果实)的气孔结构,结果显示有3种类型气孔:无规则型,不等型及平列型。参棕亚科的气孔多为平列型,少为无规则型,而牵环花亚科多为无规则型,少为不等型(Gymnophyton除外)。Bowlesia分支的细胞壁多为深波状,其他分支的细胞壁多平直。气孔结构的研究为分子系统学建立的参棕亚科和牵环花亚科,以及Bowlesia分支提供了形态学依据,并支持分子系统学将Apiopetalum,MackinlayaStilbocarpa从五加科分别移入参棕亚科和牵环花亚科,将Homalosciadium,Platysace,HermasKlotzschia移出两亚科。

Abstract: The stomatal structures of the leaves (stems or fruits) of 48 species representing 34 genera of the Apiaceae subfamilies Mackinlayoideae (9 genera) and Azorelloideae (21 genera) and their relative taxa were studied in detail for the first time. Three types of stomata - anomocytic, anisocytic and paracytic - were observed. In Mackinlayoideae, the stomata are mostly paracytic and the minority are anomocytic. In Azorelloideae, stomata are mostly anomocytic and the minority are anisocytic. Cell walls in the Bowlesia clade are deeply waved while they are usually straight in the other clades of Azorelloideae. This stomatal study provides morphological evidence for the two subfamilies and the Bowlesia clade that have been established by molecular research. It also provides evidence to support moving Apiopetalum, Mackinlaya and Stilbocarpa from Araliaceae to Mackinlayoideae and Azorelloideae, and against placing Homalosciadium, Platysace, Hermas and Klotzschia in either of these subfamilies.
