Abstract

Background: Previous studies have shown that the ultrastructure and histochemistry of flowers give insight into the pollination mechanisms of orchid species. The microscopic features of species within the Pleurothallidine subtribe are poorly understood. In this study, we investigated three Lepanthes species: L. calodictyon, L. saltatrix and L. tentaculata. These species have a similar flower morphology that is distinct from that of the other representative of the genus.

Results: Our analyses revealed the presence of features usually associated with myophily. The papillae of lips and petals of the L. calodictyon group were rich in lipids and proteins, which were correlated with high metabolic activity. Furthermore, the ultrastructural and morphological features were similar to those observed in other fragrance-emitting orchid species.

Conclusions: Histochemical, ultrastructural and morphological features of the papillae on the surface of the lips and petals of examined taxa indicate that the papillae are osmophores.

兰科蓝菖蒲、盐柳菖蒲和触须菖蒲的花解剖与超微结构。

背景：以往的研究表明，花的超微结构和组织化学有助于了解兰花的传粉机制。薄鳞鱼亚族中物种的显微特征尚不清楚。本研究调查了三种lepanthus属植物：L. calodictyon、L. saltatrix和L. tentaculata。这些种有相似的花形态，不同于该属的其他代表。结果：我们的分析揭示了通常与肌病相关的特征。calodictyon组唇部和花瓣乳头富含脂质和蛋白质，与高代谢活性相关。此外，其超微结构和形态特征与其他香兰品种相似。结论：唇部和花瓣表面乳头的组织化学、超微结构和形态特征表明其为渗透细胞。
