Article Info Received : 02.03.2017 Accepted : 23.05.2017 In this study the effect of salt stress on the concentrations of nitrogen (N) and phosphorus (P) in the leaves and the roots of two strawberry (Fragaria vesca L.) cultivars (Camarosa and Sweet Charlie) was investigated on cold stored bare-rooted seedlings grown in buckets filled with coarse sand. The treatments consisting of no-NaCl control, 1760, 2400, and 3040 mg L -1 of NaCl in half-strength Hoagland nutrient solution were applied to the plants for six months. During the experiment, leaf and root sampling were performed two times with five months interval. Roots and leaves of the plants were analyzed for Na, Cl, N and P. Analysis of variance (ANOVA) procedures was performed in Three Factors Completely Randomized Design for plant analysis results. Additionally orthogonal comparison was applied to the significant salinity effects. Cultivar and sampling time affected N, P, Na and Cl concentrations of the roots significantly. Cultivarsampling time and sampling time-salinity interactions were significant for the N, P and Na concentrations of the roots. Salinity solely affected Cl concentrations of the roots significantly. All the treatments affected the concentrations of P, Na and Cl of the leaves significantly. The N concentrations of the leaves were affected significantly by only sampling time. Cultivar-salinity and sampling time-salinity interactions were found significant in the leaf N concentrations of the plants. The results show that the cultivars probably have different strategies in arrangement of N and P composition under salinity.

In order to investigate the effect of salt stress on mineral nutrients, one year-old olive (Olea europaea L. cv. Gemlik) seedlings were exposed to increasing levels of NaCl salinity (4 dS m-1 , 8 dS m-1 and 12 dS m-1 , respectively) in pot culture and Na, K, Ca, Mg, N, P, Cl, Fe, Mn, Zn concentrations, ratios of K/Na and (K+Ca+Mg)/Na of the plants were ascertained. Sodium and Cl concentrations of plant parts increased with the salinity and the level in the aerial parts of the plants were lower than that of root. Salinity led to a general decrease in K concentrations in the all organs with the exception of subsoil trunk. Calcium concentrations of the plant parts decreased significantly by salinity with the exception of roots and subsoil trunk. Salinity affected Mg concentrations only in trunk and leaves. Treatments significantly decreased the ratios of K/Na and (K+Ca+Mg)/Na of all the plant organs. Compared to control application the highest salinity level (12 dS m-1) decreased the N concentrations of all the plant organs statistically except roots. Similarly salinity increased the concentrations of P in all plant parts except trunks compared to control treatment. Concentrations of all the micronutrients detected in the study were found lower in aerial parts than the roots.
