摘要:
 以高地钩叶藤和大钩叶藤为研究对象,采用生物解剖学方法,分析维管束和导管在径向和轴向的变化规律。结果表明,高地钩叶藤与大钩叶藤维管束径向直径、弦向直径、密度以及导管的直径和密度分别为603.23 μm和640.83 μm、451.60 μm和495.69 μm、2.87个·mm-2和2.66个·mm-2以及219.00 μm和262.46 μm、3.62个·mm-2和2.82个·mm-2。径向由藤皮至藤芯,高地钩叶藤维管束径向直径、弦向直径和导管直径均呈先升后降的变化趋势,大钩叶藤维管束径向直径、弦向直径和导管直径均呈逐渐增加的趋势,两者维管束密度和导管密度呈现逐渐降低的趋势,其中导管密度F检验在0.05水平上差异显著。随着轴向高度的增加,维管束直径高地钩叶藤变化为先减后增,大钩叶藤变化为先增后减,维管束与导管的密度高地钩叶藤变化为“降-增-降”,大钩叶藤变化为先减后增,其中维管束密度F检验在0.01水平上差异极显著。
Abstract:
 For reasonable exploitation and utilization of rattans,Plectocomia himalayana and Plectocomia assamica were chosen to systematically investigate the changes of vascular bundle and ducts in radial and axial directions by the biological anatomy method.The results showed that the vascular bundle radial diameter,vascular bundle axial diameter,vascular bundle density,catheter diameter,catheter density of P.himalayana and P.assamica were 603.23 μm and 640.83 μm、451.60 μm and 495.69 μm,2.87 N·mm-2 and 2.66 N·mm-2,219.00 μm and 262.46 μm,3.62 N·mm-2 and 2.82 N·mm-2,respectively.From cortex to core in radial direction,the vascular bundle radial diameter,vascular bundle axial diameter and catheter diameter of P.himalayana increased firstly and then decreased,but increased gradually in P.assamica; the vascular bundle density and catheter density of P.himalayana and P.assamica decreased gradually and the catheter density of them was different by the F-test at 0.05 level.With the increase of height in axial,the trend of change of vascular bundle diameter of P.himalayana decreased firstly and then increased but increased firstly and then decreased in P.assamica; the trend of change of vascular bundle density and catheter density of P.himalayana exhibited drop-rise-drop pattern and decreased firstly and then increased in P.assamica.The vascular bundle density of them was significantly different by the F-test at 0.01 level.
