已知温度和光周期都影响普通小麦品种的物侯发育。Mekinney和Sando发现冬、春两种生长习性不同的品种,需要特殊的温度和光周期的组合才能在最短的时间内完成它们的生活周期。延长光照期和增加温度就可满足一些春小麦和多数冬小麦基因型的这种要求。Syme在一次来源于澳大利亚、墨西哥和欧州的一些春性品种的研究中,发现有些品种对昼长和春化处理反映敏感,而另一些品种对两种处理都不敏感;还有一些品种对上述两种处理的不同水平有反应。Halse和Weir认为在生长期中,春化处理、光照期和温度对几个春小麦品种的抽穗期都有影响。通常,较高的温度会促进早开花。一些品种由于物候期的早期阶段缺乏低 It is known that both temperature and photoperiod affect the development of common wheat cultivars. Mekinney and Sando found that winter and spring varieties with different growth habits require special temperature and photoperiod combinations to complete their life cycle in the shortest amount of time. This requirement of spring wheat and most winter wheat genotypes can be satisfied by prolonging the light period and increasing the temperature. In a study of spring varieties from Australia, Mexico and the European Union, Syme found that some cultivars were sensitive to day length and vernalization treatments, while others were not sensitive to both treatments. Some species tested the above Different levels of both treatments respond. Halse and Weir argue that during growing season, vernalization, light and temperature have an effect on the heading date of several spring wheat varieties. In general, higher temperatures promote early flowering. Some species lacked low due to the early stages of the phenophase
