摘要:试验材料为一株260节,长约42米的小钩叶藤。分析了藤茎下列特性的轴向变异:表皮细胞的垂周长度和外壁厚变,皮层宽度,维管束的密度和纤维鞘/维管组织比值,后生木质导管分子的长度和宽度,纤维长度,以及节间的长度和直径。节间长度,民管分子长度及纤维长度的轴向变异一致,这三项特性反映茎的生长活力。
A single stem of Plectocomia microstachys with 260 nodes, about 42 meters long was sampled from a tropical mountain rain forest of Hainan Island. The axial variations in the following characteristics were measured: anticlinal length and outerwall thickness of epidermal cell; width of cortex; size, density and fibrous sheathvascular tissue ratio of vascular bundle; length and width of metaxylem vessel element: fibre length: and diameter and length of internode. The axial varistions inlength of internode, vessel element and fibre showed a similar pattern. These threecharacteristics reflected the vigor of growth of the stem.
