Using "skeleton" photoperiods with a primary photofraction of 3 hrs. 30 min. and secondary photofraction of 30 min. located at various intervals after the onset of darkness, the occurrence of a photoinducible phase in the androgenic function has been evidenced in the Ferret. This photo-inducible phase seems to be located around 12 hrs. after the onset of the primary photofraction, since the ferrets who received the 30 min. photofraction 8 hrs. after the onset of darkness responded with a maximal increase in plasma testosterone.
使用“骨架”光周期，主光段为3小时30分钟，次光段为30分钟，在黑暗开始后的不同时间间隔出现，在雪貂中已证明雄激素功能存在光诱导期。这个光诱导期似乎位于主光段开始后约12小时，因为在黑暗开始后8小时接受30分钟光段照射的雪貂血浆睾酮有最大程度的增加。
