小麦灌浆期间３０℃以上的日最高气温对百粒重有明显影响，在正常湿度、偏湿和高湿三种土壤湿度下，高温处理的百粒重分别下降８％、１９％和２３％。高温和水渍二因子对百粒重的效应相对独立，可相互累加。农林４６对湿热反应较不敏感，而宁麦３号则异常敏感。这种异主要来自品种间的耐湿性差异，并主要反映在灌浆持续时间的缩短程度上。
The daily maximum temperature above 30 ℃ during wheat filling had a significant effect on the 100-grain weight. Under normal, wet and humid conditions, the 100-grain weight under high temperature treatment decreased by 8%, 19% and 23% respectively. The effects of high temperature and waterlogging on the weight of 100 kernels are relatively independent and can be summed up with each other. Agroforestry 46 is less sensitive to moist heat, while Ningmai 3 is exceptionally sensitive. This difference mainly comes from the differences in moisture resistance among cultivars and is mainly reflected in the shortening of the grouting duration.
