The differential response of graft combinations between two mango rootstock cultivars ('13-1' and 'Turpentine') to NaCl salinity (0 and 30 mM NaCl added) was assessed. Two growth-flushes long cuttings were rooted and then grafted reciprocally to raise four graft combinations between the two rootstocks. Non-grafted cuttings were also tested. CO2 assimilation and transpiration decreased in all graft combinations during salinization. The strongest reduction was found in the combination 'Turpentine' grafted on '13-1' as a rootstock. Also the strongest reduction in shoot growth and the highest Cl- contents in leaves were found in this graft combination, indicating that '13-1' as a rootstock was not able to protect the salt-sensitive scion 'Turpentine'. '13-1' as a scion was able to maintain a significantly higher K+/Na+ ratio in the leaves, while as a rootstock it had no such effect on the scion.
