Effect of changing day length and temperature on quail testicular weight and meiosis. A, top panels, Testes of quail kept under SD and LD conditions. Scale bars, 1 cm. Bottom panels, Changes in testicular mass in quail transferred from SD to LD and then to short day/low temperature (SL; solid line) or SD (dashed line). *, P < .05; **, P < .01 vs 0 day of LD condition (0LD) (ANOVA); †, P < .05 SL vs SD (t test, n = 8–10). B, Representative photomicrographs for immunohistochemistry of SCP3, a marker of meiosis (arrowhead). Scale bars, 25 μm. C, Changes in number of SCP3-positive cells. *, P < .05; **, P < .01 vs 30LD (corresponding to 0SD/SL) (ANOVA); †, P < .05; ‡, P < .01 SL vs. SD (t test, n = 4–5).
