不同苎麻品种纤维物理性能的差异及相关性的初步研究

Preliminary Studies on Differences of Fiber Physical Properties and Its Correlation among Different Varieties of Ramie (Boehmeria nivea L.)

比较研究107个不同苎麻品种纤维物理性能,结果表明:单株原麻干重、有效株、断裂功、纤维支数、断裂强力(强度)变异系数较大;单株原麻干重与纤维支数极显著负相关,与断裂强力(强度)显著正相关,与株高极显著正相关;纤维支数与断裂强力(强度)极显著负相关,与断裂伸长(伸长率)极显著负相关;纤维断裂强度强度与断裂伸长伸长率呈极显著正相关,与断裂功极显著正相关。

ramie (Boehmeria nivea L.) varieties are studied. The results show that the variation coefficient of dry weight of crude fiber, available plants, fineness of fiber and breaking strength (tenacity) are higher in all test items. Dry weight of crude fiber per plant is negatively correlated with counts of fiber at 1% level, and it are positively correlated with breaking strength (tenacity) at 5% level, and with height of plant at 1% level. Fineness of fiber are negatively correlated with breaking strength (tenacity) and breaking extension (extensibility) at 1% level. Breaking strength (tenacity) is positively correlated with breaking extension (extensibility) and breaking work at 1% level.
