Consequences of Nacl Salinity on Growth and Ion Accumulation in Selected Strawberry Cutivars

Abstract

Salt-tolerance of some strawberry cultivars was examined using frigo plants grown in hydroponics. The cultivars 'Tioga' and 'Rapella' were more salt-tolerant than strawberry cultivars 'Camarosa', 'Sweet Charlie', 'Dermarvel', 'Tudla', 'Northester' and 'Douglas'. Vegetative growth in these cultivars was better compared to strawberry cultivars 'Elvira', 'Aiko', 'Camarosa', 'Sweet Charlie', 'Dermarvel', 'Tudla', 'Northester' and 'Douglas' under 100 mM NaCI treatment. Considering vegetative growth parameters, cvs 'Dermarvel', 'Douglas' and 'Camarosa'. Generally, Na accumulation caused by NaCl was higher in sensitive cultivars than in tolerant cultivars. The Ca/Na and K/Na ratios were larger in tolerant cultivars. Malondialdehyde contents of all cultivars increased due to NaCl. Nevertheless, no relationship between malondialdehyde content and salt tolerance of cultivars could be determined.
