【摘要】 墨西哥香荚兰(Vanillafragrans(Salisb.)Ames(V.planifoliaAndr.))茎叶解剖学特征研究表明:香荚兰茎表皮具气孔;茎中内皮层为厚壁组织(纤维);维管茎束散生于环状厚壁内皮层所包围的基本组织中,靠近内皮层的维管束相对较小,各维管束外围具有厚壁维管束鞘细胞.香荚兰叶为等面叶,叶肉细胞无海绵组织和栅栏组织的分化.叶的气孔器仅分布在下表皮,而上表皮无气孔器.保卫细胞为肾形.更多还原

【Abstract】 The transverse and longitudinal section of mature stem of Vanilla planifolia showed that the endodermis was sclerenchyma,which positioned between cortex layer and the vascular tissue region.There was an atactostele in the stem.The leaf of Vanilla planifolia was isobilateral leaf,and it was shade plant.The stomatal apparatus of leaf only existed in under epidermis,which was absent in upper epidermis.The guard cell was reniform, which was distinctly different from that of common monocotyledons.更多还原
