1. EFFECT OF SALINITY ON VINES AND WINES BEN AMI BRAVDO The Hebrew University of Jerusalem

3. THE CAUSES OF SOIL SALINITY HIGH CONCENTRATIONS OF SALTS IN IRRIGATION WATER OR FERTILIZER INSUFFICIENT IRRIGATION TO LEACH SALT OUT OF THE ROOT ZONE POOR SOIL STRUCTURE THAT LIMITS DRAINAGE OR LEACHING OF SALTS OUT OF THE ROOT ZONE NON UNIFORM WATER APPLICATION ACROSS THE IRRIGATED AREA, RESULTING IN LOCALIZED PATHCHES OF INADEQCUATE LEACHING SALINATION OF THE ROOT ZONE BY HIGH WATER TABLES WHICH MAY BRING SALTS FROM OTHER AREAS OR FROM SOIL THE BELOW

4. AUSTRALIAN SOURCES SENSITIVE TO MODERATELY SENSITIVE 3.6dS/m OWN ROOTS –V.VINIFERAe.g. SULTANA,SHIRAZ,CHARDONNAY MODERATELY TOLERANT TO TOLERANT 6.6 dS/m ROOTSTOCKS: e.g. RAMSEY, 1103 PAULSEN, 140 RUGGERI, 101-14, RUPESTRIS ST. GEORGE
