Abstract : The effects of using saline water (1.1 mixture of NaCl and Na2SO4; 0, 0.1, 0.2 or 0.4%) as irrigation water and Cycocel [chlormequat] (3 sprays each at 50 ppm) on growth and uptake of some elements by Taimour and Alphonso mango seedlings were investigated during 1994-95 in Egypt. Increasing salinity reduced all growth characters (height, number of leaves, leaf area and stem thickness) and caused adverse effects on the uptake of N, P, K, Ca, Mg, Zn and Fe. Taimour and Alphonso exhibited similar sensitivities to salinity. Salinity at levels of >0.2% adversely influenced the uptake of nutrients. Cycocel treatment effectively alleviated the adverse effects of salinity.
