摘要:

为了阐明芦竹纤维素和木质素含量与居群的关系以及与生长发育时期的关系,从而为开发利用芦竹资源提供依据,分别采用酸碱洗涤法和Klason法测定了8个居群芦竹成熟期的纤维素和木质素含量,并测定了芦竹2个居群在不同生长期的纤维素和木质素含量。结果表明:(1)芦竹同一居群不同部位的纤维素与木质素含量由高到低均为:秆>枝>叶;(2)8个居群芦竹纤维素含量由高到低依次为:浙江嵊州芦竹>南京市郊西解芦竹>湖南衡阳芦竹>浙江慈溪芦竹>江苏阜宁芦竹>湖南凤凰芦竹>贵州铜仁芦竹>云南洱源芦竹;纤维素含量最高的是采自浙江嵊州的样品,为49.2%;(3)8个居群芦竹木质素含量由高到低依次是:湖南凤凰芦竹>贵州铜仁芦竹>云南洱源芦竹>浙江嵊州芦竹>南京西解芦竹>湖南衡阳芦竹>江苏阜宁芦竹>浙江慈溪芦竹,木质素含量最高的是采自湖南凤凰县的样品,为27.7%。(4)随着生长期的延长,芦竹的纤维素和木质素含量都有不同程度的提高,在生长期2~6个月时增长快,此后6个月增长缓慢。

Abstract:

The methods of acid-base washing procedure and Klason procedure were used to measure the content of cellulose and lignin of eight different habitats of Arundo donax respectively, and the contents of cellulose and lignin of two populations of Arundo donax at different stages of growth were measured in order to explicate the relation between the stage of growth, the populations and the content of cellulose and lignin, and therefore providing evidence for exploiting Arundo donax. The results showed that: (1) in the same population, the contents of cellulose and lignin from the highest to the lowest were all stem, branch and leave. (2) As for the stems of all samples, the contents of cellulose from the highest to the lowest were the habitats of Shengzhou of Zhejiang Province, Xijie of Nanjing, Hengyang of Hunan, Cixi of Zhejiang, Funing of Jiangsu, Tongren of Guizhou and Eryuan of Yunnan Province. The sample of Shengzhou had the highest cellulose content which was 49.2%. (3) From the highest content of lignin to the lowest, they were habitats of Hengyang in Hunan Province, Eryuan of Yunnan, Xijie of Nanjing, Tongren of Guizhou, Shengzhou of Zhejiang, Funing of Jiangsu, Hengyang of Hunan and Cixi of Zhejiang Province. Stems in Fenghuang had the highest lignin contents, which was 27.7%. (4) The contents of cellulose and lignin from eight populations increased at different degrees with the growth of time, and they increased very fast in 2-6 months, and then increased very slowly.
