Abstract
Glycine betaine(GB)is an important compatible solute that is associated with stress tolerance in plants under low-temperature stress.To investigate the effect of exogenous GB on the physiological indexes of Zoysia japonica under low-temperature stress,GB at 0,50,100,and 150mmol/L was applied as a foliar spray to‘Qingdao',aZ.japonica cultivar,before transferring the plants to growth chambers.The plants were grown under average temperatures of 8℃/2℃(day/night)for 28 days in the low-temperature treatment,and under average temperatures of 28℃/24℃(day/night)in the control.Exogenous GB alleviated the loss of turf quality and chlorophyll content,and reduced the increase in electrolyte leakage and malondialdehyde content in Z.japonica under low-temperature stress.Exogenous GB increased the activities of superoxide dismutase,peroxidase,catalase,and ascorbate peroxidase,leading to lower H2O2 and O2·-contents.Also,exogenous GB enhanced the osmotic adjustment capacity of the plants by increasing the concentrations of proline and soluble protein.These results indicated that exogenous GB enhanced the resistance of Z.japonicato low-temperature stress,and 100mmol/L exogenous GB was the most effective concentration.
