Physiological and biochemical responses of two precious Carpinus species to high-concentration NO2 stress and their natural recovery

Abstract Carpinus betulus and Carpinus putoensis are precious species in the world. Studies on the ecosystem function of the two species are rare. This study investigated the physiological and biochemical responses of C. betulus and C. putoensis to NO2 stress and their natural recovery. C. betulus a...
