Fig. 6 Expression characteristics of SiPRR37 gene under different photo-thermal combinational treatments A: the effect of different photoperiods on SiPRR37 gene under low temperature condition; B: the effect of different temperatures on SiPRR37 gene under short-day condition; C: the effect of different temperatures on SiPRR37 gene under long-day condition; D: the effect of different photoperiods on SiPRR37 gene under high temperature condition. Long day: 6:00-21:00 light, 0:00-6:00 and 21:00-0:00 dark; Short day: 6:00-15:00 light, 0:00-6:00 and 15:00-0:00 dark. LTSD: low temperature short day; LTLD: low temperature long day; HTSD: high temperature short day; HTLD: high temperature long day. Different uppercase and lowercase letters above the bar represent significant difference at the 0.01 and 0.05 probability levels, respectively.
