通过对１９９８年３月２０～２４日不同小麦品种晚霜冻害的观察表明：小麦对晚霜冻害的敏感期是雌雄蕊原基形成到药隔前期之间、幼穗冻伤率与霜冻时茎节长度呈显著的正相关。从小麦形态长相划分，竖叶型、叶色深绿、分蘖力强的品种较抗晚霜冻，春性品种较半冬性品种抗晚霜冻。
By observing the frost damage of different wheat varieties from March 20 to March 24, 1998, the sensitive period of wheat to the frost damage was that the primordium of the pistil and stamen formed between the prepartum and the frostbite, Significant positive correlation. From the wheat morphology looks divided, vertical leaf type, dark green leaf color, strong tillering ability than the late frost, spring than the semi-winter varieties resistant to late frost.
