Özet

In this study, 500, 1000 and 1500 mg I-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.
