肉豆蒄天竺葵是一种含有精油的植物,其精油被广泛应用于香料与化妆品。然而其精油的产生部位腺毛的结构与发育过程尚未有研究,本文应用光学显微镜、扫描电子显微镜、透视电子显微镜对肉豆天竺葵腺毛结构及其发育过程进行了研究。结果表明:在肉豆天竺葵叶的表皮上具有腺体毛和非腺体毛两种结构形态。在研究中发现,肉豆天竺葵只有头状腺毛(由头细胞、柄细胞和基细胞三个部分组成),其头状腺毛可以分为两种类型:类型Ⅰ和类型Ⅱ。肉豆天竺葵腺毛是由表皮细胞发育而来。
Pelargonium Pelargonium is a plant containing essential oils, the essential oils are widely used in spices and cosmetics. However, the structure and development of glandular hairs at the site where essential oils are produced have not been studied yet. In this paper, the structure and development of glandular hairs of geranium pelargonium were studied by optical microscope, scanning electron microscope and transmission electron microscope. The results showed that there were two kinds of morphological features of glandular hair and non-glandular hair on the epidermis of the leaves of pelargonium geranium. In the study, it was found that there are only two types of head glandular hairs: type I and type II, which have only the head glandular hairs (composed of head, stem and basal cells). Mud bean geranium glandular hair is derived from epidermal cells.
