Changes of Some Macro- and Micronutrients Accumulations of Strawberries Plants (Fragaria X Ananassa Dutch L.) Under Salt Stress
(Asian Journal of Chemistry, 2009) Yilmaz, Hudai; Yildiz, Kenan; Kina, Arzu; Oguz, H. Ibrahim
In this study, gloria and kabarla strawberry varieties plants are taken for trial at solid medium culture. During the development, Hoaglan solution is added salt (NaCl) doses of 0 (control), 500, 1000,1500 mg L-1. At the end of the trial, all plant parts above the soil level (aerial parts) are used for the determination of macro (N, P, K, Ca, Mg) and micro (Mn, Zn, Cu, Fe, B) elements, At the analysis done, it was determined that both of the varieties are affected from the salt stress and the accumulation levels change according to the salt doses. It was observed that the kabarla variety with the development characteristics is more tolerable to salt stress when compared with the gloria variety. It was observed that the salt applications on kabarla variety caused an increase in the accumulation of N, Ca and Mn and the accumulation of other elements led to a decrease. In the gloria variety, the increasing salt doses led to a decrease in the accumulation of all the elements whereas at the elements Zn, Fe and B in the 500 mg L-1 application which is the lowest water dose, an increase with respect to the control was determined. In the gloria variety, increase of Zn, Fe and B at 500 mg mg L-1 salt dose turned to a decrease again after the increase in the following doses.
The Influence of Nacl Salinity on Some Vegetative and Chemical Changes of Strawberries (Fragaria X Ananssa L.)
(Academic Journals, 2008) Yilmaz, Hudai; Kina, Arzu
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.
