14小时的光和10小时的黑暗（LD 14：10）的制度诱导退化的睾丸和附属腺在成年Djungarian仓鼠最初维持在LD 16：8，但复发的仓鼠这些器官最初维持在LD 8：16。无论仓鼠是否来自LD 16：8或LD 8：16，LD 14：10中夜间褪黑素水平升高的持续时间是相同的。建议夜间褪黑激素峰值的持续时间及其方向的变化，而不是褪黑激素峰值的绝对持续时间可能是一种激素信号驱动成年Djungarian仓鼠的光周期反应。
A regime of 14 h of light and 10 h of darkness (LD 14:10) induced regression of testes and accessory glands in adult Djungarian hamsters maintained originally in LD 16:8, but recrudescence of these organs in hamsters maintained originally in LD 8:16. Duration of the period of elevated nighttime melatonin levels in LD 14:10 was the same irrespective of whether hamsters had come from LD 16:8 or from LD 8:16. It is suggested that a change in duration of the nighttime melatonin peak and its direction rather than absolute duration of the melatonin peak may be a hormonal signal driving photoperiodic responses in adult Djungarian hamsters.
