| 摘 要： | 【目的】了解生态环境对新疆冬小麦品种面团流变学特性的影响。【方法】选择用新疆7个冬小麦品种于2009、2010年在6个海拔区(473～1 422 m)种植,探讨生态环境对冬小麦品种面团流变学特性的影响。【结果】面团流变学特性指标在基因型、环境(除形成时间外)间呈显著或极显著差异。不同品质类型品种间、不同地点间冬小麦面团流变学特性变化不同。三种筋型冬麦品种在稳定时间、评价值、最大拉伸阻力间的差异均显著;中强筋类和中弱筋类的形成时间、延伸性差异不显著,与强筋类差异显著;强筋类和中强筋类的吸水率、弱化度差异不显著,与弱筋类差异显著。随着海拔递增,三种筋型小麦弱化度升高,最大拉伸阻力、拉伸面积则降低。强筋类面团流变学特性主要指标在乌鲁木齐点表现最好,于田点最差。生态因子与面团流变学特性的分析表明,海拔高度与吸水率、弱化度呈极显著正相关,与延伸性、最大拉伸阻力、拉伸面积呈极显著负相关。平均温度与吸水率、形成时间、评价值呈显著或极显著负相关;与延伸性、拉伸面积、最大拉伸阻力呈显著或极显著正相关。光照对吸水率、形成时间呈显著正效应,与弱化度、最大拉伸阻力、拉伸面积呈显著或极显著负效应。而降水量与面团流变学特性的相关性均不显著。【结论】强筋类品种在新疆北部地区的表现好于南部地区;而中强筋和中弱筋类在上述区域均适宜种植。

| Abstract: | 【Objective】The influence of environment on dough rheology parameters of Xinjiang winter wheat cultivars was researched.【Method】In 2009 and 2010,seven representative winter wheat cultivars were grown at six different altitude locations(473-1 422 m),and the influence of environment on dough rheology parameters of winter wheat cultivars was researched.【Result】Analysis shows that the dough rheology parameters in locations and genes are extraordinary or significant except for development time.The dough rheology parameters of winter wheat cultivars are different among quality types and locations.Three quality types winter wheat cultivars differences in stable time,evaluation values and the resistances-max are all extraordinary;The development time and extension show no extraordinary different between the middle strong and the middle weak gluten wheat,which are significantly different from the strong gluten one;The development time and extension display no significant difference between the middle strong and the strong gluten wheat,which are significantly different from the middle weak one.With the altitude increasing,the degree of softening is also increasing in three gluten wheats.But the area and the resistances-max are reduced.Analysis also shows that the Urumqi’s quality is the best and Yutian’s is the worst.According to the analysis of the correlations of ecological factors and dough rheology parameters,we can know the altitude is highly positively correlated to water abortion and degree of softening,and negatively to to extension,area and the resistances-max.The mean temperature is extraordinarily or remarkablly minus to water abortion,development time and evaluation values;it is extremely positive to extension,area and the resistances-max.The sunshine is greatly positive to water abortion and development time,and significantly minus to degree of softening,the resistances-max and the area.The correlations of precipitation and dough rheology parameters are not significant.【Conclusion】The strong gluten wheat in Northern Xinjiang is much better than that growing in Southern Xinjiang.But the middle strong and the middle weak gluten wheat are suitable to be planted in all the locations in our region,in Northern or Southern Xinjiang. |
