摘要:本研究测定黄竹薄壁细胞在多维度下的形态参数,分析各维度对形态参数的影响规律。结果表明,黄竹薄壁细胞分布于维管束周围,壁薄腔大且形态多样。从时间维度而言,竹龄会显著影响黄竹薄壁细胞除宽度外的形态参数,其中壁厚的F值高达65.45。从位置维度而言,轴向高度对黄竹薄壁细胞的所有形态参数均具有极显著影响(P<0.01)。径向部位是影响黄竹薄壁细胞壁厚和腔径变化的关键因素,从竹青生长到竹黄,黄竹薄壁细胞的壁厚、腔径分别从1.31、19.87 μm增至1.92、37.65 μm,且竹青壁腔比最大(0.14),竹黄最小(0.11);不同节间部位的黄竹薄壁细胞形态存在差异,其中下部近竹节薄壁细胞的长度、宽度、壁厚和腔径均高于上部近竹节。
Abstract:In this study, the morphological parameters of parenchyma cells in Dendrocalamus membranaceus were measured across multi-dimensions, and the patterns of effects of each dimension on these morphotogical parameters were analyzed. The results indicated that parenchyma cells in Dendrocalamus membranaceus were distributed around the vascular bundles, characterized by thin walls, large lumens, and diverse morphologies. From temporal perspective, bamboo age significantly influenced the morphological parameters (except for width) of parenchyma cells in Dendrocalamus membranaceus, with the F value for wall thickness reaching as high as 65.45. From spatial perspective, axial height had an extremely significant effect (P<0.01) on all morphological parameters of parenchyma cells in Dendrocalamus membranaceus. The radial position was a key factor affecting wall thickness and lumen diameter, showing an increase from 1.31 and 19.87 μm at the outer layer (bamboo green) to 1.92 and 37.65 μm at the inner layer (bamboo yellow), respectively, and the wall-to-lumen ratio was highest at the outer layer (0.14) and lowest at the inner layer (0.11). There were morphological differences in the parenchyma cells of Dendrocalamus membranaceus at different internode regions. Specifically, parenchyma cells near the node in the lower internodes exhibited greater length, width, wall thickness, and lumen diameter than those near the node in the upper internodes.
