摘要:
 以贵州省内自然分布的14个种源的山棕纤维为材料，测量单纤维形态特征和纤维束拉伸性能等性状。结果表明，山棕纤维种源间单纤维的长度和直径，纤维束的直径、断裂强度、杨氏模量、断裂伸长率的差异均达极显著水平，表明山棕纤维性状变异丰富；不同种源间回潮率变幅最小，差异不显著，但明显高于其他一些植物纤维。相关性分析表明，种源的纤维形态与各项力学性能相关关系均不显著。据此，在培育时可在种源水平上对各性状进行独立选择，有望获得良好的效果。
Abstract:
 This study aimed to test and analyze the palm fiber characteristics of 14 provenances naturally occurred in Guizhou Province.Morphological features of single palm fiber,tensile properties of fiber bundles were measured and analyzed.Extremely significant differences were found in relative parameters among different provenances,including the length and diameter of single palm fiber,fiber bundle diameter,tensile strength,Young’s modulus,and rupture elongation,which indicated that the variations of the characters of palm fiber were rich among different provenances.The moisture regain had no significant difference,but much higher than some other plant fibers.Correlation analysis showed that the relationship between the morphology and mechanical properties of the fibers was not significant.It was hopeful that good results could be obtained if the characters were selected independently among different provenances when cultivating.
