摘要
本文首次采用了GMA半薄切片和厚壁区域细胞分离法,深入研究了东北唇形科52种及5变种(位于4亚科26属)的果实形态结构。结果显示,果实多为三棱形,有的物种果实的棱延伸形成翅。果实表面光滑、具网纹或不同类型的毛状体(包括头状或盾状腺毛,单细胞、单列多细胞或分枝非腺毛)。着生面多为圆形,少为直线形或"V"形。果皮分为外果皮、中果皮、厚壁区域和内果皮。晶体常存在厚壁区域。本研究完善了东北唇形科果实形态学,并为进一步研究中国唇形科果实结构和分类学以及分子系统学奠定了基础。
The fruit structures of 52 species and 5 varieties representing 26 genera from 4 subfamilies of Lami- aceae in northeasten China were deeply studied in the paper for the first time, using glycol methacrylate（GMA） sections and cells of the sclerenchyma region were separated for identifying the structure. The results show that the fruits of the family are mainly trigonous in shape, sometimes the edges of the fruits extend and form wing. The fruit surfaces are glabrous, reticulate or with hairs （including capitate or peltate glandular hairs, unicellu- lar, uniseriate multicellular or branched non-glandular hairs）. The areola of the fruit is mainly round, barely linear or V-shape. The pericarp could be divided into four parts, exocarp, mesocarp, selerenchyma region and endocarp. The crystal exists in the sclerenchymatous region. The study completes the fruit anatomy of Lami- aceae in northeasten China and provides the basis for the further research of the fruit anatomy and taxonomy, and molecular systematics of Lamiaceae in China.
