    • Abstract
  • The effects of exogenous Spd on NO3--N,NH4+-N,Pro contents and NR activity of salt stressed leaves and roots of cucumber seedlings in hydroponic culture were studied.The results showed that exogenous Spd could reduce salt-stress-induced increase of NH4+-N,Pro contents and reduce decrease of NO3--N contents and NR activity,and salt tolerant cucumber was less affected than salt sensitive cucumber.It is indicated that exogenous Spd could alleviate salt stress on cucumber seedlings.
