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.
Cultivar-sampling 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.
