title: [Effect of abscisic acid on physiological characteristics in Lonicera macranthoides seedlings under salt stress].
abstract: OBJECTIVE
  To improve salt resistance of Lonicera macranthoides seedlings and provide reference for its cultivation of salt tolerance.
  
  
  METHODS
  Pretreatment of seedlings with abscisic acid (ABA) of different concentrations were used to study the effect of ABA on their physiological and biochemical characteristics under 200 mmol/L NaCl for 7 days.
  
  
  RESULTS
  Exogenous ABA significantly decreased the content of malondialdehyde (MDA), increased the contents of chlorophyll, soluble sugar, soluble protein and activities of protected enzymes such as peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD).
  
  
  CONCLUSIONS
  It is proposed that exogenous ABA as chemical activator can induce salt resistance and decrease alleviate damage degree of salt stress of Lonicera macranthoides seedlings in a dose-dependent manner.
