Abstract:
Taking ‘Weike No.3’yellow-skin watermelon as materials，the effects of photosynthetic bacteria on photosynthesis and antioxidant enzyme activities in leaves were studied by foliage sparaying method.The results showed that,spraying 1×109-4×109 CFU/mL PSB on leaves of watermelon decreased the decomposition of chlorophyll to alleciate the damage of photosystem and antioxidant enzyme system，effectively protect the membrane system under low temperature stress，greatly improve the resistance of watermelon.The optimal concentration to spray on leaves of watermelon was 4×109 CFU/mL PSB，but 8.0×109 CFU/mL PSB would be toxic to watermelon seedlings.
