| 摘 要： | 以广东、广西和海南3个省(区)8个产地的粉单竹群体3年生竹秆为研究材料,对其纤维形态、化学成分等纸浆材性指标进行测定,采用方差分析和相关分析方法对上述竹材性状进行遗传变异分析,以揭示粉单竹材性的地理遗传变异规律.结果表明: (1)粉单竹的纤维长度、纤维素和1%NaOH抽出物含鼍在产地间存在极显著或显著差异.纤维长度及纤维长宽比呈现纬度上从南到北(海拔上从低到高)逐渐减小的地理变异模式;(2)纤维素和纤维长度的遗传力分别为O.71和O.84;1%NaOH抽出物遗传力为0.54;木素和纤维长宽比的遗传力分别为O.38和O.13; (3)性状间相关分析表明,竹材产量与1%NaOH抽出物和苯醇抽出物呈显著负相关,与纤维素含量呈显著IE相关;纤维形态与生长、产量指标关系密切;最后,通过主成分分析进行联合选择,初步选出材性质量好、生长旺盛、竹材产量高的广东怀集、广东信宜和广西桂林3个优良纸浆材产地.

| Abstract: | Using 3-year-old culms of 8 provenances of Bambusa chungii from Guangdong, Guangxi and Hainan Provinces, the indexes of wood properties, such as fiber dimensions and chemical composition were investigated and analyzed by the methods of Analysis of variance and correlation coefficient to reveal the geographic genetic variation situation. The results showed that there are significant differences between fiber length, fibrin and 1% NaOH extraction contents of B. chungii from 8 provenances; moreover, the fiber ... |
