The aim was to study exogenous GB on cold resistance of Phoebe microphylla. Taking one-year-old Phoebe microphylla seedlings as materials, effects of different concentrations (50. 100. 150 mmol•L-1) exogenous GB on cold resistance of Phoebe microphylla under low temperature. Under low temperature stress, foliar spraying of different concentrations GB significantly decreased malonaldehyde (MDA) content, Relative conductivity, and increased chlorophyll, Soluble protein, Soluble sugar, peroxidase (POD), superoxide dismutase (SOD) activities in Phoebe microphylla. Among 3 kinds of GB concentrations, 150 mmol•L-1 GB was the best for Phoebe microphylla on cold resistance. A certain concentration GB preprocessing mitigates the harm of low temperature stress on Phoebe microphylla seedling, and improves their ability of cold resistance.
