To study the effects of Salicylic acid(SA)on physiological indexes of Rhododendron hybridumunder low temperature stress,the seedlings of cultivar of Fenhong were pretreated with Salicylic acid of different concentration(0.3、0.5、1.0、1.5、2.0 mmol·L-1),with spraying water as the control.and the physiological indexes changes of Rhododendron hybridum under low temperature at 0℃ for 4days were observed.The results showed that SA solution of different concentration could improve the chilling tolerance of seedlings,among which the 0.5 mmol·L-1 solution was the best.
