小麦花后常遇高温胁迫，显著影响小麦产量和品质。为了探讨高温热害对小麦品质影响的内在原因，现对灌浆期高温胁迫对小麦籽粒各蛋白组分积累及品质方面的影响进行了综述。总体来看，高温均使小麦籽粒各蛋白质组分含量提高，当处于适度高温时，面团强度增强，小麦品质提高；当温度大于30℃形成高温胁迫时，影响谷蛋白大聚体的形成，导致面团强度变弱。进一步探讨了抗高温育种策略，以期为培育品质稳定型小麦品种提供依据。

High temperature are common in many of wheat growing areas and can be a significant factor in re‐ducing yield and quality of wheat .In order to investigate the major cause for effect of heat stress on wheat qual‐ity ,the impact of heat stress during grain‐filling stages on fractional protein accumulation and quality was re‐viewed .In general ,grain fractional protein content increased at elevated temperatures .When daily mean temper‐ature was up to 30℃ during grain filling the dough strength was improved ,and that as temperature increased a‐bove 30℃ ,the dough strength decreased .Furthermore ,breeding strategies for improving heat stress tolerance in wheat were suggested ,so as to provide useful information for breeding programmes and enhance the wheat quality .
