为评价几种瑞香科植物的纤维品质,分析了不同地区北江荛花、了哥王、多毛荛花、细轴荛花和狼毒2~3年生枝条韧皮或根皮纤维化学组分、纤维形态和细胞壁超微结构。结果表明,①不同地区北江荛花(64.25%~72.31%)、肇庆细轴荛花(71.33%)、多毛荛花(65.6%)和狼毒(59.04%)综纤维素含量均高于或接近优质传统手工纸原料檀皮(61.43%)和构皮(67.50%),而木质素含量均低于檀皮和构皮;②融水北江荛花纤维最长(5.51 mm),其次为遂昌北江荛花、肇庆北江荛花和狼毒,分别为5.40、5.09和5.05 mm,而茂名北江荛花纤维最短,仅为3.09 mm。融水北江荛花、肇庆北江荛花纤维长宽比较大,分别为565.2、538.4;③超微结构显示,城步北江荛花、融水北江荛花、遂昌北江荛花、肇庆北江荛花以及多毛荛花韧皮纤维细胞壁较薄,而茂名北江荛花、肇庆细轴荛花、狼毒和肇庆了哥王韧皮纤维细胞壁较厚。 |
Abstract: |
To assess the fiber quality of various Thymelaeaceae plants, the chemical components, fiber morphology, and cell wall ultrastructure of 2~3-year-old phloem or root bark fibers of Wikstroemia monnula, W. indica, W. pilosa, W. nutans, and Stellera chamaejasme collected from different regions were investigated. The results showed that holocellulose content of W. monnula (64.25%~72.31%), W. nutans (71.33%), W. pilosa (65.6%), and S. chamaejasme (59.04%) from different regions was significantly higher or comparable, compared with the traditional high-quality handmade paper raw materials—bark fiber of Pteroceltis tatarinowii (61.43%) and Broussonetia papyrifera (67.50%), while the lignin content was lower. The fiber length of W. monnula from Rongshui was the longest (5.51 mm), followed by Suichang (5.40 mm), Zhaoqing (5.09 mm), and S. chamaejasme (5.05 mm), whereas the fiber length of W. monnula from Maoming was the shortest (3.09 mm). The fiber length-to-width ratios for W. monnula from Rongshui and Zhaoqing were 565.2 and 538.4, respectively. The ultrastructural analysis indicated that the cell walls of phloem fibers of W. monnula from Chengbu, Rongshui, Suichang, Zhaoqing, and W. pilosa were thinner, whereas those of W. monnula from Maoming, W. nutans and W. indica from Zhaoqing, and S. chamaejasme were thicker. |
