摘　　要：于2007~2009年在洛阳研究了播期对不同生态型和筋力型冬小麦品种加工品质的影响。结果表明:不同生态型小麦品种的弱化度均表现为适播处理显著高于早播和晚播处理;在形成时间、稳定时间和粉质指数方面,半冬性品种均表现为晚播处理显著高于早播和适播处理,弱春性品种均表现为适播处理显著高于早播和晚播处理;不同筋力型品种的形成时间、稳定时间和粉质指数均以晚播处理较高,而中筋品种和弱筋品种的弱化度以适播处理较高;半冬性小麦品种的拉伸阻力、延伸度和拉伸比均以早播处理较高,拉伸面积和最大拉伸阻力均以晚播处理较高;弱春性小麦品种的拉伸面积、拉伸阻力和拉伸比均以晚播处理较高,最大拉伸面积以早播处理较高,而延伸度以适播处理较高;不同筋力型品种的拉伸面积均以晚播处理较高。The author researched the effect of sowing date on the processing quality of different types of winter wheat varieties in Luoyang during 2007 - 2009. The results showed that the weakening degree of different ecotypes of wheat varieties in the optimal sowing date treatment （T2） was significantly higher than that in the early sowing date treatment （T1） and in the late sowing date treatment （T3）. The formation time, stability time and flour quality index of semi-winter varieties in T3 were significantly higher than those in T1 and T2 ; while the formation time, stability time and flour quality index of weak-spring varieties in T2 were sig- nificantly higher than those in T1 and T3. The formation time, stability time and flour quality index of different gluten-types of wheat varieties in T3 were relatively high ; while the weakening degree of both middle-gluten varieties and weak-gluten varieties in T2 was relatively high. The tensile resistance, tensile elongation and tensile ratio of semi-winter wheat varieties in T1 were rela- tively high, while their tensile area and maximum tensile resistance in T3 were relatively high. The tensile area, tensile resistance and tensile ratio of weak-spring wheat varieties were higher in T3, their maximum tensile area was higher in T1, while their tensile elongation was higher in T2. The tensile area of different gluten-types of wheat varieties was higher in T3.
