Abstract
Uniform-size, six-month old seedlings of seven mango (Mangiferaindica L.) rootstocks, namely Moovandan, Bappakai, Nekkare, Kurukkan, Olour, Terpentine, and Chandrakaran, were treated with tap water containing 0, 50, 100, and 150 mM NaCl at four days interval for 40 days. NaCl stress caused a reduction in K+, Ca2+, Mg2+, Zn2+, and Fe2+ concentrations in all rootstocks; however, it increased the accumulation of Mn2+ and Cu2+ in tissues. Based on the nutrient status up and down in rootstocks, it could be said that salinity tolerance is found in the following order: Olour>Terpentine>Kurukkan>Nekkare>Bappakai>Moovandan>Chandrakaran.
