In this study, mangrove seedlings Kandelia obovata were firstly introduced to Zhoushan in Eastern China at 29° 93′ N from Xuwen in South China at 20° 34′ N in April 2016. In order to analyze ecophysiological differences of K. obovata seedlings domesticated in Zhoushan, the growth status and antioxidant system of K. obovata exposed to natural low temperature were studied through situ measurements. The results showed that K. obovata seedlings introduced artificially to Zhoushan grew slowly when subjected to natural cold stress. The chlorophyll contents exhibited a decreased tendency. In addition, 2-butanol and 2,3-butanediol were firstly found in K. obovata after being moved to Zhoushan, which are specific substances produced by K. obovata under low-temperature stress. Moreover, there was a synergistic competition mechanism in the antioxidant enzyme system in K. obovata, in which superoxide dismutase (SOD) would convert oxygen radicals to hydrogen peroxide, and then catalase (CAT) and peroxidase (POD) could work together to remove hydrogen peroxide. This study provides a foundation for better understanding of the response of mangroves to natural low temperature at high latitudes.
