摘要：本文描述了棕榈科省藤属及黄藤属共24种藤茎的导管分子。毛鳞省藤(Calamus thysanolepis Hance)仅具单穿孔板,其余藤种均有单穿孔板和复穿孔板,但具复穿孔板导管分子的数量少,并且大部分存在于维管区外围。此外,观察到少数具复穿孔板的螺纹导管分子。自茎的外围向内,后生木质部导管分子的宽度增大;多数藤种的导管分子长度呈增大的趋势,部分藤种则相反,或无规律。
The vessel elements of rettan canes in 24 species of Calamus and Daemonorops genera have been described. Only simple perforation plates occur in C. thysanolepis Hance. All the other species have both simple perforationplates and multiple perforation plates,but the proportion of the vessel elementswith multipleperforation plates is small, and most of them occur in the peri-phery of vascuclar zone. In addition, a few spiral vessel elements withmultiple perforation plates have been observed. From the stem bark to thecentre, the width of vessel elements in metaxylem increases; the length ofvessel elements in most of the species shows an increasing trend and partspecies contrary, or no regular pattern.
