| 摘 要： | 对特产于云南省的2个藤种盈江省藤和版纳省藤的纤维、导管、维管束和薄壁细胞的形态大小进行显微观测分析.结果表明:藤茎横向(内、中、外部)差异较大,纵向(上、中、下部)呈规律性变化.纤维长度、维管束分布密度、纤维胞壁厚度等自藤皮向藤芯减小,藤皮与藤芯的维管束分布密度差异较大;纤维宽度、导管分子长度与宽度和维管束大小等自藤皮向藤芯增大.与版纳省藤相比较,盈江省藤的纤维壁厚及纤维、导管和维管束尺寸等较大,维管束分布密度均匀,而且在藤茎横向的内外差异较小,变化梯度平缓,材质较版纳省藤的好,是特产于云南的优秀棕榈藤种.版纳省藤和盈江省藤在纤维、导管、维管束、薄壁细胞及表皮细胞等各解剖因子上均有差异,从解剖角度而言,2藤种应为南巴省藤的不同变种,解剖学证据支持《中国植物志》及《云南植物》上对2藤种的处理.

| Abstract: | The anatomical characteristics including vessel,fiber,vascular bundle,sizes and shape of parenchyma cells of two endemic rattan species in Yunnan province,namely Calamus nambariensis var.yingjiangensis and C.nambariensis var.xishuangbannaensis were micro-observed and analyzed.The results showed that there were big differences in radial horizontal direction（core,middle and cortex parts） and regular changes in vertical direction（up,middle and bottom）.All the fiber length,distribution density of vascular bundle,fibrous wall thicknesses,etc.decreased from cortex to rattan core.The difference at the distribution density of vascular bundle between rattan cortex and core was significant.Fibrous width,length width of the vessel molecule,the size of vascular bundle and so on increased from the cortex to core.Comparatively,the wall thickness of fibrous cell,size of fiber,vessel molecule and vascular bundle of Calamus nambariensis var.yingjiangensis were bigger than those of C.nambariensis var.xishuangbannaensis.Moreover,regular distribution density of vascular bundle,insignificant variation and slower change at the radial direction were main characteristics of Calamus nambariensis var.yingjiangensis.Therefore the cane quality of Calamus nambariensis var.yingjiangensis was superior to that of C.nambariensis var.xishuangbannaensis.Owing to more significant differences in anatomical characteristics above mentioned,Calamus nambariensis var.yingjiangensis and C.nambariensis var.xishuangbannaensis should be different varied species in terms of anatomic perspective.The anatomical characteristics supported their position in Flora of China and Flora of Yunnan. |
