通过对我国20世纪60年代以来应用广泛的27份骨干亲本自交系的秸秆纤维成分研究,结果显示自交系秸秆纤维品质中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、纤维素(CELLU)、半纤维素(HCELLU)和木质素(ADL)平均含量分别为47.657%、24.551%、21.096%、20.906%和3.776%;不同自交系间秸秆NDF、ADF、CELLU和ADL含量呈显著或极显著差异,HCELLU无显著差异性;各纤维组分含量之间具有显著或极显著相关性;不同年代间自交系秸秆纤维品质NDF、ADF、CELLU、和HCELLU含量有相似的变化规律,即20世纪90年代初至今各组分含量较高;ADL含量在不同年代自交系秸秆中含量变化不大。
The results showed that the inbred lines of straw fiber of NDF, ADF, Cellulose (cellulose) fiber, CELLU, HCELLU and ADL were 47.657%, 24.551%, 21.096%, 20.906% and 3.776%, respectively. The contents of NDF, ADF, CELLU and ADL in different inbred lines were significantly different Or HCELLU. There was a significant or very significant correlation between the contents of various fiber components. The content of NDF, ADF, CELLU and HCELLU in the fiber quality of inbred lines had similar changes in different years, That is, from the early 90s of the 20th century to the present, the content of each component is high. The content of ADL in the straw of inbred lines in different years has little change.
