摘　　要：研究了两个大麦品种籽粒发育期β-葡聚糖含量动态及与气象因子的关系.结果表明,大麦籽粒β-葡聚糖含量既受品种遗传特性控制,又受环境条件(气象因子)的影响.籽粒发育期β-葡聚糖含量动态,品种间基本相似,而年份间差异较大,其动态模式与粒重变化相似,与粒重和单粒蛋白质量动态呈正相关;气象因子对β-葡聚糖含量动态有显著影响,其中籽粒发育期的总积温影响最大,两者呈显著负相关.The dynamics of β-glucan content of two barley varieties during kernel development phase and the effect of some meteorological factors on (β-glucan content were studied. The results showed that β-glucan content in kernel is both dominated by genotype and influenced by meteorological factors. The model of dynamic during kernel development phase is very similar in both barley varieties, but differs in years greatly. It is showed that the dynamic of β-glucan content during kernel development phase is completely consistent with those of kernel-weight increase and protein accumulation per grain. The dynamic of β-glucan content in barley kernel is significantly influenced by meteorological factors, and there is significantly negative relationship between accumulated temperature during kernel development phase and β-glucan content in kernel.
