In this study, 500, 1000 and 1500 mg l-1 salt
applications in Kabarla and Gloria cultivars of
strawberry
in solid media culture were performed along with Hoagland
nutrient solution. In the experiment, some vegetative growth
and chemical changes were determined in the plants to which
salt (NaCl) was applied compared with the control. At the
end of the experiment, it was observed that Kabarla cultivar
grew better under saline conditions compared to Gloria. It
was observed that vegetative growth was generally
restricted, depending on the increase in salt applications.
Especially, damages on leaves became significant. It was
determined that the increased salt doses affected
chlorophyll and
malondialdehyde levels, but these values were not sufficient
to determine salt-tolerant cultivars. It was found that Na+
ion
accumulation on root, crown and leaves of the plant and ion
accumulation ratios of
K+/Na+
and Ca2+/Na+ had significant effects
on tolerance to saline conditions.
Higher
Na+
ion
accumulation and ion accumulation ratios of
K+/Na+
and Ca2+/Na+ were obtained in case of
Kabarla, which was understood to grow better under saline
conditions. These values stayed lower in case of Gloria.
