| 摘 要： | 人工霜箱的控制试验表明， 冬小麦叶片冻结后是否受到伤害取决于最低叶温。 拔节后第1 ～20天， 叶片的霜冻临界叶温由-6.5℃提高到-4.5℃。 幼穗是否受伤与最低叶温的关系相 当密切， 同期 幼穗轻度伤害的临界叶温由-8.3℃提高到-3.9℃， 幼 穗严重伤害的临界叶温 由-8.3℃提高到-5.4℃。 建立了叶受害、 穗轻伤、 穗重伤的

| Abstract: | The relationship between frost damage and leaf temperature of winter wheat after jointing stage was researched by controlled experiment with artificial frost ap paratus. The result indicated that it was determined by the minimum leaf tempera ture whether suffers from frost injure after the leaf free |
