环境对大麦籽粒啤用品质性状的影响

为了解环境对大麦籽粒啤用品质的影响,研究了10个大麦品系在6个试点中籽粒的长、宽、厚、千粒重和蛋白质含量等5个与啤用品质相关的性状,分析了不同性状在品系、试点间的差异性及各性状间的相关性。结果表明:参试品系的籽粒长度、宽度、厚度、千粒重在不同品系间、试点间的差异均达极显著水平；籽粒蛋白质含量在不同试点间的差异达极显著,而品系间的差异不显著。

Effects of environment on grain characters related with malting quality of barley

In order to understand the effects of environment on grain characters related with malting quality, including grain length, width, thickness, 1 000-grain weight and grain protein content were evaluated among 10 barley varieties which grown in 6 locations. The differences in varieties and locations and the correlation coefficients among five grain characters were studied. The results showed that the differences in grain length, width, thickness and 1 000-grain weight were highly significant among varieties and trial locations. The difference in protein content was highly significant among trial locations, while it was not significant among varieties.
