Abstract

Melon cultivars that are sensitive and tolerant to salinity were reciprocally grafted and
plants were grown under salinity and control conditions in the glasshouse. Growing culture
was vermiculite and plants were irrigated by the complete nutrient solution. Thirty days old
melon plants, grafted and ungrafted were subjected to salinity stress during 25 days with
100mM NaCI. Some physiological parameters were investigated. Grafting on the tolerant
melon increased the responses of the sensitive melon to salinity in comparison to the
ungrafted one. The shoot fresh weight and leaf area were increased by 27%, leaf water
potential was increased by 65%, leaf membrane injury index was decreased by 13 and
stomatal conductance was increased by 18%. Other parameters like chlorophyll content, leaf
temperature, mineral content (Na, K, Ca, and Cl) of the leaf and root, antioxidative enzyme
activities were also investigated. All results were discussed in the meeting in Portugal.
