| Abstract: | The role of acetylsalicylic acid (0, 1 and 10 μM) pre-treatment in amelioration of salt and osmotic stress in a wild species
of potato (Solanum stoloniferum) was investigated. We compared the effects of iso-osmotic concentrations of polyethylene glycol 6000 (15 %) and NaCl (80
mM) on the physiological responses of this species in explants grown in the liquid Murashige and Skoog medium. Both salt and
drought reduced shoot growth parameters, photosynthetic pigment contents and increased lipid peroxidation, electrolyte leakage,
H2O2 content and lipoxygenase activity. The effect of NaCl was more severe than that of polyethylene glycol. Salinity also increased
Na+ content and decreased K+ content and K+/Na+ ratio. Under both stresses, the activities of superoxide dismutase, guaiacol peroxidase, ascorbate peroxidase, catalase and
glutathione reductase enzymes were increased. Acetylsalicylic acid pre-treatment alleviated the adverse effects of both stresses
on all parameters measured. |
