EFFECTS OF SODIUM CHLORIDE, KINETIN AND CYCOCEL ON ACCUMULATION OF SOME ELEMENTS IN OLIVE (OLEA EUROPAEA L. "DEZFUV")

Salinity is a limiting factor for plant growth and crop production. A study was conducted to determine the salt tolerance of olive (Olea europaea L. "Dezful") and its effects as combined with application of kinetin and cycocel plant growth regulators on Na, K, and Cl distribution. The experiment was carried out in a completely randomized design with factorial arrangements with four replications. Accumulation of Na, K. and Cl in aerial parts and roots of plants were determined. The results indicated that increasing salinity level caused an increase in Na and Cl but a decrease in K/Na ratio. Sodim concentration was higher in the roots whereas Cl accumulation was higher in aerial parts. Application of 250 mg 1-1 kinetin at the 200 mM salinity level increased Na concentration of leaves. Application of cycocel (1000 mg 1-1) decreased Na accumulation in roots. The decrease was statistically singnificant (P<0.05) at 100 mM salinity level.
