贵州小麦品质与生态效应研究

为给小麦优质生产品种的合理布局提供依据,以8个小麦品种为材料,对贵州小麦品质与其生态效应进行了初步研究.结果表明,贵州省生态环境对小麦籽粒的蛋白质含量与湿面筋含量影响较大,而沉淀值与面团稳定时间受小麦基因型的影响较大.贵州属强筋、中筋、弱筋小麦的混作区,东西两端属中筋、弱筋小麦混作区,中部属强筋、中筋小麦混作区,弱筋小麦所占比例最大,其次是中筋小麦,强筋小麦所占比例最小.不同品种在不同地区小麦籽粒的蛋白质含量、湿面筋含量、沉淀值、面团稳定时间差异明显,其中面团稳定时间是影响小麦籽粒品质的限制性指标.弱筋小麦面团稳定时间与小麦拔节至成熟期的日较差、总降雨量呈二次曲线关系,日较差和总降雨量最优取值分别为8.55℃和404.375 mm,与日平均最高温度、日平均温度呈显著正相关,与总日照时数呈显著负相关.

Quality and Ecological Effect of Wheat in Guizhou Province

This article is on the quality and ecological effect of the eight wheat varieties in Guizhou.The results indicated that ecological environment had more influence on protein content and wet gluten content in wheat than genotype.Guizhou belongs to the mixture area of the strong,middle and weak gluten wheat,its east and west area belong to the mixture area of middle and weak gluten wheat,its middle area belongs to the mixture area of strong and middle gluten wheat.The wheat with weak gluten has the biggest per...
