Abstract
The response of cucumber plants (Cucumis sativus L) to salinity at four salinity concentrations (2.5, 4.5, 6.5 and 8.5 mS cm-1) was studied.
The fresh and dry weight of the root and shoot were significantly reduced with increasing nutrient solution salinity, while the dry matter percentage was increased.
The root:shoot ratio was not affected.
Total yield was significantly reduced when salinity increased.
Plant water uptake and relative water content were significantly reduced at high salinity condition.
Plant water potential was decreased with increasing salinity levels.
Similarly, the transpiration rate and stomatal conductance were reduced by increasing salinity.
The photosynthetic rate was unaffected by salinity.
Ca and K% in the dry matter of the root and leaves were decreased while the Cl and Na% were increased with increasing nutrient solution salinity.
