Effect of water salinity stress on dates biometric and biochemical characteristics

Abstract

The problem of water irrigationin palm groves led us to conduct this study based on the comparison of the quality of dates Deglet Nour and Ghars from two farming systems in the region of El Oued according to thesaline water irrigation degree. Salt stress in El Ghout causes in both varieties a regression of biometric characteristics, pH, EC, water content and dry matter, while total sugars are high. The dates of the farm are more voluminous, less acidic, with high ash content, dry matter and high electrical conductivity. According to standards Algerian of date classification reveals that the characteristics of Deglet Nour dates of El Ghout are more damaged by increasing the water salinity. The two varieties of the farm have better characteristics than those of El'Ghout. It's also appears that saline water irrigation improves the sugar content of dates
