Among abiotic
stresses salinity is the most detrimental factor in limiting crop productivity. In this study, the effect of
different sodium chloride (NaCl) concentrations (0, 50, 100, 150, 200, 250 mM)
on growth and physiological parameters of Pistacia
lentiscus L. seedlings raised in in vitro condition for 4 weeks was
investigated. For this purpose the seeds of Lentisk were germinated in
Murashige and Skoog, (1962) basal mediums containing different NaCl
concentrations. The morphological, physiological and biochemical changes that
occurred in the seedlings were measured and recorded after exposure to salt
stress. These results show that visible
leaf damage of Lentisk seedlings are affected by high salt
concentrations. High salinity concentrations significantly reduce root and stem
lengths, relative water content (RWC), total chlorophyll, Cl-a, Cl-b and
carotenoid values after the culture periods. At 250 mM salt concentration, root
and stem growth were found to be completely stopped. The parameters over the
50 mM salt concentrations caused in decrease in the activity of the antioxidant
enzyme peroxidase (POD).
