本文旨在研究枫香树木交错纹理的变化形式、变异性及其相关因子。利用偏振光显微镜测量小试样交错纹理变化的方法,研究了安徽省南部两个地区的三块样地中七株枫香树木交错纹理。结果表明,所有样木均存在着不同程度的交错纹理,其径向变化呈变振幅、变周期的正弦振荡曲线形。交错纹理不仅在生长轮之间及生长轮之内,而且在同一生长轮的不同高度上反复改变。经方差分析检验,同一样地的株间及株内的等树高处不同方位之间,交错纹理变异有着显著差异。而地区、样地及不同树高处之间差异不显著。交错纹理变化几乎与树木生长速率无关,但可能影响次生壁S_2层微纤丝的排列。
The purpose of this paper is to study the variations, variability and related factors of the staggered texture of Liquidambar formosana. Using polarized light microscopy to measure the interlacing texture variation of small samples, the interlacing texture of seven Grifola trees in three plots in two areas of southern Anhui Province was studied. The results show that all the samples have different degrees of staggered texture, the radial variation is a sinusoidal oscillation with varying amplitude and varying period. The interlacing texture is not only changed between growing wheels and growing wheels, but also repeatedly at different heights of the same growing wheel. Analysis of variance analysis showed that there were significant differences in staggered texture variation between different azimuths at the same tree height and in the same tree. However, there was no significant difference between the regions, the plots and the height of different trees. Interlaced texture changes are almost independent of the tree growth rate, but may affect the arrangement of S_2 microfibrils in the secondary wall.
