Cottonseed exposed to a temperature of 5 degrees during hydration are killed, or the subsequent germination performance of surviving seed is seriously inhibited. Exposure to chilling for periods as short as 30 minutes reduces germination speed and induces root abnormalities, while chilling for 12 hours may kill all seed. Sensitivity to chilling persists during the initial 2 to 4 hours of hydration. Seeds imbibed 4 hours at 31 degrees , then dried, retain immunity to chilling. An irreversible event that is blocked or disrupted by chilling apparently occurs during early seed hydration.
棉籽在水合过程中暴露于 5 度的温度下会死亡，或者存活种子的后续发芽性能会受到严重抑制。暴露在 30 分钟的冷却温度下，会降低发芽速度并诱导根异常，而 12 小时的冷却可能会杀死所有种子。在最初的 2 到 4 小时的水合过程中，种子对冷却敏感。在 31 度下吸胀 4 小时然后干燥的种子，保留对冷却的免疫力。在早期种子水合过程中，显然会发生一个被冷却阻断或打乱的不可逆事件。
