摘要
对中国云南省木莲属的大果木莲、红花木莲、亮叶木莲、大叶木莲、粗枝木莲、密脉木莲、锈毛木莲、薄叶水莲等8种植物的木材进行了解剖特征的研究,其中粗枝木莲又密脉木莲的导管分子端壁具有单穿孔,密脉木莲导管分子内壁有螺纹加厚,并在大果木莲和亮叶木莲发现傍管的薄壁组织。
The anatomical characters of 8 species in Manglictia B1. are described as follows: Diffuse-porus woods; porese 10～37 per sq. mm, perforation plates scalariform with 4～7 bars (may be up to 15), simple perforation in an end wall might be observed in M-anglietia pachyclada and M. polyneura; with spiral thickenings in M.polyneura; vessel elements 659～1040 μm long, tangential diameters 66--106μm wide; wood rays heterogeneous, type 11 with 3～5 rows of upright cells on both margins; fiber-tracheids 1220～1720μm long. Changes in length of vessel elements and fiber-tracheids are related to the age of woods. In addition, the anatomical characters of woods of 8 species are compared.
