Salinity Effect on Concentration, Uptake, and Relative Translocation of Mineral Nutrients in Four Olive Cultivars

The aim of this greenhouse study was to investigate the distribution of some ions in four olive cultivars, (Olea europaea L., cvs. 'Zard', 'Conservolea', 'Manzanila', and 'Mission') under saline conditions. One-year old olive seedlings were planted in the plas...

Description
Summary:The aim of this greenhouse study was to investigate the distribution of some ions in four olive cultivars, (Olea europaea L., cvs. 'Zard', 'Conservolea', 'Manzanila', and 'Mission') under saline conditions. One-year old olive seedlings were planted in the plastic pots contained 1:1 sand: perlite medium and irrigated with one-half strength Hoagland's No. 1 nutrient solution. A completely randomized design with factorially arranged treatments and four replications was used. Four salinity treatments [0, 40, 80, and 120 mM sodium chloride (NaCl)] were used during 100 days. At harvest, shoot and root dry matter yield as well as concentration of mineral nutrients was separately determined in root, apical and basal leaves. There was significant (P < 0.05) difference among cultivars in concentration, uptake, and relative translocation of sodium (Na), chloride (Cl), and potassium (K) in different plant tissues. 'Conservolea' cultivar had the highest Na and Cl and the lowest K concentration in apical and basal leaves. In all cultivars, with increasing salinity, the tissue concentration of Na and Cl increased while the K concentration decreased. The results showed that under saline conditions, the distribution of mineral nutrients in olive depends on both plant cultivar and the ion of interest.
