摘　　要：为探明海拔梯度对不同粒色青稞品质的影响及营养品质含量之间的差异,利用分层聚类、相关性及主成分分析法对80份青稞品种(系)在3个海拔梯度下的青稞籽粒中淀粉、蛋白质、膳食纤维、花青素和维生素E含量共5个籽粒品质性状进行分析。结果表明:不同海拔梯度下的80份青稞样品作方差分析,3个地区取得的数据按照海拔高低两两做差可以分为6类,73.75%的青稞蛋白质含量随着海拔的升高而降低且有显著差异,45%青稞淀粉含量随着海拔的升高先升高后降低且有显著差异,46.25%的青稞维生素E含量随着海拔的升高而降低且有显著差异,81.25%青稞花青素含量随着海拔的升高先升高后降低且有显著差异,40%青稞膳食纤维含量随着海拔的升高而升高并有显著差异。In order to investigate the influence of altitude gradient on the quality of hulless barley with different grain color and the differences of nutrient content,the present study used hierarchical clustering,correlation analysis,and principal component analysis to analyze the contents of five seed quality traits(starch,protein,dietary fiber,anthocyanin,and vitamin E)in 8o barley varieties(lines)at three altitude gradients.The results showed that the 8o barley samples from the three regions were subjected to a one-way ANOVA,and the data obtained from the three regions were divided into six categories according to the altitude.The protein content of 73.75%hulless barley decreased with increasing altitude and showed a significant difference.45%of the barley starch content increased first and then decreased with increasing altitude and showed a significant difference,46.25%of the barley vitamin E content decreased with increasing altitude and showed a significant difference.81.25%of the barley anthocyanin content increased first and then decreased with increasing altitude and showed a significant difference,4o%of the barley dietary fiber content increased with increasing altitude and showed a significant difference.
