The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

竹笋生长阶段是先结晶后木素化的过程，一个月内细胞壁结晶组织基本形成；2）一年生竹材的植株秆茎生长结束，秆茎的高度、粗度和体积变化不大，但秆茎的组织幼嫩，含水量高，干物质少，竹材结晶度基本不变；3）二年生竹材的植株开始木质化，纤维素比例降低，结晶度减少，到后期竹子木质化降低，竹材结晶度变化不大；4）多年生竹材的结晶度没有太大的变化，结晶度大小处于波动状态；5）畸形竹材纤维帽细胞壁结晶区的厚度比正常竹小，其横截面结晶区的面积、纤维帽长轴与短轴比有所减少，而圆形度、异型指数有所加大，单位面积纤维帽的密度增大。
