The effect of different photoperiods and temperatures on pineal 5-methoxytryptophol (ML) content was investigated in male box turtles, Terrapene carolina triunguis. A rhythm in pineal ML was evident in the long photoperiod (18 h light (L)-6 h dark (D] with high daytime levels of 178 +/- 48 pg/gland (means +/- S.E.M.) which dropped to 38 +/- 6 pg/gland during lights off. In the short photoperiod (8L:16D) no clearcut ML rhythm was observed. Diurnal (10.00-12.00 h) ML concentrations rose linearly (P less than 0.05) with increasing ambient temperatures (5, 15, 20 and 27 degrees C). Day/night differences in ML levels, however, were not significant. Pineal ML in the box turtle thus seems to be modified by the photoperiod and, to a lesser extent, by temperature.
