一般来说，小麦的耐寒性应该是指在低于最适生长温度（约20℃）的条件下的表现，不同品种在低温条件下的生长速度存在明显差异，因此对凉爽气候的适应也存在差异。然而，“耐寒性”一词最常用于描述植物对冰冻温度的反应，这对作物有更大的影响。最常见的情况是，冬季的低温会影响秋种小麦。抗冻性指的是更广义的“冬季耐寒性”，这是秋播谷物的一种属性，它负责“冬季生存”或“越冬”的差异。
In a general sense, cold tolerance in wheat should refer to performance at temperatures lower than the optimum for growth (about 20oC), and there are definitely differences in the growth rate of cultivars at low temperatures and, consequently, in their adaptation to cool climate. However, the term “cold tolerance” is most frequently used to describe a plant’s response to freezing temperatures, which have more dramatic effects on the crop. Most often, freezing temperatures affect autumn-sown wheat during winter. Freezing tolerance refers to the broader term of “winter hardiness,” an attribute of autumn-sown cereals that is responsible for differences in “winter survival” or “overwintering.”
