生态条件对大麦产量及β-葡聚糖含量的影响

为明确不同生态条件下大麦籽粒产量及β-葡聚糖含量的环境效应,选取了11个不同的大麦品种,在全国6个生态条件有差异的试点种植。结果表明,各试点间大麦籽粒产量差异显著,襄樊试点平均产量最高;苏啤3号大麦在6个试点的平均产量最高,达5391.7kg/hm2,与其他品种差异显著。各试点及各品种间,大麦籽粒β-葡聚糖含量差异也达到显著水平。G231M004M大麦在6个试点β-葡聚糖含量的平均值显著高于其他品种;各个大麦品种在保山试点的籽粒β-葡聚糖含量均明显高于其他试点。因此,选取特定品种种植在适宜的生态条件下对调节大麦籽粒产量和β-葡聚糖含量具有积极意义。

EFFECT OF ECOLOGICAL CONDITIONS ON YIELD AND β-GLUCAN CONTENT OF BARLEY

To reveal the environmental effects on the yield and β-glucan contents of barley grain, eleven barley cultivars were selected and planted on six locations with different ecological conditions. The result showed that there were significant difference about barley yield among different locations, the average yield in Xiangfan was the highest. The average yield of Supi 3 were 5391.7kg/hm2, which was significantly higher than other cultivars. Effects of planting locations and different cultivars on the β-glucan contents of barley gain were obvious. G231M004M's average contents of β-glucan in all six locations were the highest, and was obvious difference compared with other cultivars. The β-glucan content of 11 cultivars in Baoshan location was obviously higher than other locations. These results indicated that it is important and effective to select specific cultivars and plant under suitable ecological conditions to improve the yield and β-glucan contents in barley grain.
