Salt Tolerance of Three Muskmelon Cultivars1

Abstract
The salt tolerance of 3 muskmelon cultivars (Cucumis melo L. cv. Top Mark, PMR 45, and Hale's Best) was determined in plots artificially salinized with NaCl and CaCl2. Marketable yield, total dry weight, vine dry weight, and total fruit weight of all cultivars decreased with increasing salinity. ‘Top Mark’, the highest yielding cultivar at low salinity, yielded least at high salinity. ‘PMR 45’ was the least affected with increasing salinity. Na and Cl in the leaves and fruit and % soluble solids in the fruit all increased with increasing salinity levels.
