In this paper, the relationships between package types, storage way, storage time as well as stroage conditions of bare-root seedlings and dehydration degree were studed the relationships between dehydration degree and physiological-biochemical indices such as peroxidase(POD), catalase(CAT), polyphenol oxidase(PPO),malonyl-diadehyde(MDA), the conductivity value, the resistance value as well as the moisture content were determined the experiments were performed using dehydration degree, planting method and t...
