Abiotic and biotic stresses both decrease quality and quantity of cultivated plants. We compared responses
of Cucumis sativus L. cvs Sardes and Beith alpha which were treated with 50 or 100 mM NaCl
and/or infected by Pseudoperospora cubensis Berk. and Curt. Rostov.. Both cultivars were affected
remarkably when fungus infectionwas combined with salt stress however; cv Sardes was found out to be
relatively tolerant with sustainable growth performance, better leaf water status and lower lipid peroxidation
levels under this condition. This relative tolerance could be related to the fine tuning of the
activities of the antioxidative enzymes and proline levels.
