摘要
应用光学显微镜、扫描电子显微镜和激光扫描共聚焦成像显微镜对海桑属 6种红树植物木材结构进行观测 .首次报道了海桑属植物具有纤维状导管分子 ,并对其生态学意义进行了讨论 .同时对其次生木质部的形态结构特征的共同点和不同点进行了总结和描述 ,以作为比较解剖学的依据 ,进一步讨论海桑属与红树植物其它属木材结构相异的原因 .对海桑属与同一科的八宝树属(Daubanga)
The morphological features of secondary xylem in six species of Sonneratia p lants were survered by means of optical microscope, scanning electronic microsco pe and laser scanning confocal microscope. Fibriform vessel elements in Sonner atia plants were first reported and their ecological significance was discusse d. Similarities of wood features in Sonneratia plants were represented as wo od comparative evidence for comparing it with other mangrove genera Bruguiera, Ceriops, Kandelia, Rhizophora, Avicennia, Aegiceras. The results showed that a few w ood features in Sonneratia were recognized to delimit it except for uniserat e rays. Comparison of wood anatomical features between Sonneratia and Daub anga , belonging to the same family, suggests that they are possibly treated as two separate tribes.
