摘要:

Effects of continuous light and dark periods and long and ultrashort photoperiods on the gonadal function of a subtropical finch, Spotted munia, hitherto considered “non‐photosensitive”, were studied. This bird seems to be unique in that while gametogenesis and hormone production are stimulated by the continuous or long scoto periods the endogenous rhythm of reproduction continues in constant 24hr or 15hr long daily photoperiod.
