摘要
从偏光显微镜获得竹材细胞壁结晶区的图像,利用图像处理方法,对不同生长期的毛竹茎秆横截面结晶区大小进行了研究。结果表明:从竹笋到幼竹这一生长阶段,原生导管及原生筛管的细胞壁首先形成结晶,然后后生筛管细胞壁结晶,而且随时间推移结晶区面积逐渐增大;在竹笋生长后期,纤维帽逐渐形成且不断增大,薄壁细胞壁呈现结晶。
Using the image obtained by using polarizing microscope and the image processing technology, the variation of the crystalline in cell wall of moso bamboo （Pkyllostackys edulis） at cross section during shoot development period was studied. The result indicates that the moso bamboo cell walls of proto-vessels and proto-sieve tubes were firstly crystallized during the development from shoot to young culm, and the area of crystalline increases little by little. With the moso bamboo growth, the vascular bundle begins to enlarge and the parachyma cell wall also crystallizes.
