【摘要】：采用传统的化学成分测试方法和激光扫描共聚焦显微镜技术(CLSM)研究了杞柳的化学成分以及木质素在各细胞及纤维细胞各微区的分布,分析了株高不同部位化学成分的变异规律。结果表明:杞柳的1%Na OH抽提物、热水抽提物、冷水抽提物、苯醇抽提物、综纤维素、α-纤维素、酸不溶木质素、酸溶木质素、多戊糖和灰分分别为32.11%、10.85%、7.11%、3.27%、70.46%、35.50%、20.18%、4.50%、15.51%、0.90%;在不同部位,除了α-纤维素和多戊糖含量差异不显著,其余各指标均差异显著;木质素在各细胞及纤维细胞各微区分布不均一,导管细胞壁木质素浓度高于木纤维和射线,纤维细胞角隅处木质素浓度高于次生壁和复合胞间层。
[Abstract]:Using the traditional chemical composition test method and laser scanning confocal microscopy (CLSM) study on the chemical composition and distribution of Salix wood in various cells and fiber cells of each micro region, analysis of chemical constituents in different parts of the high strain variation. The results showed that 1%Na OH extract osier, hot water extract, cold water extract, alcohol benzene extractive, holocellulose, alpha cellulose, acid insoluble lignin, acid soluble lignin, pentosan and ash were 32.11%, 10.85%, 7.11%, 3.27%, 70.46%, 35.50%, 20.18%, 4.50%, 15.51%, 0.90%; in different parts, in addition to differences of alpha cellulose and pentosan content was not significant, other indexes were significantly different; lignin in various cells and fiber cells of each micro inhomogeneous distribution of xylem cell wall lignin concentration is higher than that of wood fiber and ray, fiber cell corner lignin concentration is higher than the secondary wall and composite cell Interlayer.

【正文快照】： 杞柳(Salix integra)主要分布在我国黄河和淮河流域,是一种种植简单、速生丰产的丛生落叶灌木,隶属于杨柳科(Salicaceae)柳属(Salix)。杞柳的传统用途是作为一种优良的编织用材生产手工产品,或编制成包装材料应用在包装和建筑等领域。然而,材料利用率低、产品种类单一、结构简
