Abstract: The aim of the study was to understand the impact of different sowing time on grainβ- glucan content and the dynamic variation of grainβ- glucan in barley.‘Supi6’and‘Zangqing 25’were used as research materials in this study. The grainβ-glucan content for each material was tested at different stage after flowering in condition of three sowing times in two years. The results showed that: the grainβ-glucan content in‘Supi6’was not affected by sowing time, while it in‘Zangqing 25’was affected significantly by sowing time and reached the highest in early November. With normal sowing time, grainβ-glucan content concentration in barely was increased gradually from blossoming to the 30th day after flowering and was stabilized after that. Accumulation rate ofβ-glucan content reached two peaks at 1-5 days and 20-25 days after flowering. The effect of the sowing time was different on different barleys, and 1-5 days and 20-25 days after flowering were the key time of the accumulation rate.
