山东省主推小麦品种品质性状的近红外光谱分析

以山东省主推的25个小麦品种为材料,利用近红外光谱技术对其籽粒蛋白质含量、湿面筋含量、吸水率和面团稳定时间进行了检测.结果表明,44.O%,小麦品种的蛋白质含量大于14.0%,48.0%小麦品种的蛋白质含量介于14.0%和12.0%之间;湿面筋含量大于32.O%的小麦品种占60.O%.湿面筋含量大于28.O%而小于32.0%的小麦品种占32.O%;48.0%小麦品种的吸水率大于60.0%:20.O%小麦品种的面团稳定时间大于7.0min,72.0%小麦品种的面团稳定时间介于7.0min和2.5.0min之间:有4个小麦品种的蛋白质含量、湿面筋含量和面团稳定时间达到强筋麦2级以上标准(GB/T17892-1999),占16.0%,其余21个品种为中筋麦.

Analysis of the main quality traits of wheat varieties big acreage planting at Shandong in last two yers

The PC, WA, WG and ST of 25 wheat varieties planted in Shandong province were determinated by near infrared spectroscopy technology.The results showed that the protein content of 44.0%wheat varieties was higher than 14.0%, the protein content of 48.0% wheat varieties was between 14.0% and 13.0%;the wet-gluten content of 60.0% wheat varieties was higher than 32.0% and that of 32.0% wheat varieties was between 32.0% and 28.0%;the water absorption of 48.0%wheat varieties was higher than 60.0%;the stability time of 20.0%wheat varieties was higher than 7.0min and that of 72.0% wheat varieties was between 7.0min and 2.5.0min.The PC, WA, WG and ST of 4 wheat varieties(16.0%) were up to the Chinese standard of strong gluten wheat(GB/T17892-1999), and 21 wheat varieties were middle gluten wheat.
