Abstract
Mango is one of the most important tropical fruits in Iran and salinity is an important problem to mango production in ‘Hormozgan’ province and other mango growing areas in Iran. At present experiment the effects of saline irrigation water of different sodium chloride concentration on vegetative growth and ion content of mango was evaluated. Treatments comprised two type of cultivars (‘Sendry’ and ‘Charak’) and four water irrigation salinity regimes (1.5, 3.0, 4.5 or 6.0 ds/m). Results showed that salinity significantly decreased shoot and root dry weight, water content and increased root/ shoot dry weight ratio. Salinity significantly increased the sodium and chloride ions in shoot or roots and decreased the potassium content in roots. Also, salinity decreased the potassium/ sodium ratio in roots and shoots. The results demonstrated that ‘Sendry’ cultivar was slightly more tolerant to salinity than ‘Charak’.
