木质

Lmt.The characteristics and novelty in this dissertation was obvious in the following aspects: cofermentation of glucose and xylose to ethanol by recombinant yeast S. cerevisiae ZU-10, ethanol production from hydrolysates of cellulose and hemicellulose in corn stover by recombinant yeast S. cerevisiae ZU-10, and integration of key technologies in ethanol production from lignocellulosic biomass. These results were meaningful not only in academic research, also in utilization of renewable lignocellulosic biomass, decreasing the production cost of fuel ethanol , and alleviating the world grain crisis.

Therefore, we deduce that the formation of parchment is originated from morphological changes of cells adjacent to endodermal and it not only closely relate to cell lignificantion, but aslo consiste of sclerenchym cells which had higher contents of cellulose and hemicellulose.

因此，可以推断在内果皮细胞发育分化形成的革质膜不仅是细胞的木质化，而且是由含有大量纤维素和半纤维素并高度木质化的厚壁细胞构成。

The study was conducted to investigate the effects of heat treatment on flesh leatheriness of cold-stored loquat fruits and the possible mechanisms. Freshly harvested loquat fruits were pre-treated with hot air at 38℃ for five hours and then stored at (1±1)℃ for 35 days. Fruits firmness, extractable juice rate, the activities of phenylalanine ammonium-lyase, peroxidase, polyphenol oxidase and polygalacturonase that were related to flesh leatheriness, and contents of lignin and pectin were analyzed at seven-day intervals during storage.

为阐明热处理对冷藏枇杷果实木质化败坏的影响及其机理，该研究先将枇杷果实用38℃热空气处理5 h，然后在(1±1)℃下贮藏35 d，并每隔7 d测定果实硬度、出汁率、苯丙氨酸解氨酶、过氧化物酶、多酚氧化酶和多聚半乳糖醛酸酶等木质化相关酶活性及果胶和木质素含量的变化。

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。

Cupule subglobose, 3.5-4.5 cm in diam., completely enclosing nut, wall 4-6 mm thick and ± woody when dry; bracts subulate, 6-10 mm, woody and multiangular, base 4-8 mm in diam., apex shortly pointed.
