12种润楠属植物叶柄解剖学特征研究
Petiole Anatomy of 12 Machilus Plants
摘要
Abstract
Petiole of 12 Machilus plants was taken as the research object. The anatomical characteristics of transverse section of the central part of petiole were observed under light microscope with paraffin section method. The results showed that the central shape of petiole of 12 Machilus can be divided into Ω shape and horseshoe shape. The types of the upper petioles shape could be fell into two broad headings,concave and convex. The shape in epi-dermis cells of petiole were rectangle or nearly circular, vascular bundle length-width ratio, petioles length-width ratio and lower epidermis to the vascular bundle relative distance ratio were also different,which those differences mi-cromorphological characters could serve as one of the criteria to identify species of taxonomic Machilus.In addition,the number and distribution of oil and mucilage cells also had a certain reference role in plant classification of Machilus.关键词
