Mitigation of salinity stress in cucumber seedlings by exogenous hydrogen sulfide.

This research hypothesized that tolerance of cucumber seedlings to salinity stress could be increased by hydrogen sulfide (HS) treatments. In pot experiments, the cucumber seedlings were exposed to three levels of salt stress (0, 50 and 100 mM NaCl), and NaHS as HS donor was foliar applied to the cucumber seedlings at five different doses (0, 25, 50, 75 and 100 µM). The effects of the treatments on cucumber seedlings were tested with plant growth properties as well as physiological and biochemical analyses.
