NaCl Stresinin Bazı Armut ve Ayva Anaçlarının Yaprak Bakır, Bor, Çinko, Demir ve Mangan İçeriklerine Etkisi.

Salinity is one of the most important abiotic stress factors limiting the productivity in higher plants. The nutrition imbalance in plants that exposed to salinity caused deterioration of cell integrity which leads to the impairment of metabolic functions that are vital for plants. The research was carried out repeatedly for two years. In 18 liter pots pear (OHxF 97, OHxF 333, Fox 11) and quince (BA 29) rootstocks were stressed which containing control, 20 mM, 40 mM and 80 mM NaCl. At the end of study the changes of Fe, Cu, Mn Zn and B elements that occur in leaves together with salt stress were investigated. According to the results of the research, Fe, Cu, Mn, Zn and microelement contents in different pear and quince rootstocks under NaCl stress varied over the years depending on the rootstocks and salt concentration. Especially in plants exposed to heavy NaCl stress (80 mM), it was observed that the existing changes were more clear. Compared to the two-year average, the total microelements intake decreased by approximately 6% in saline conditions. It was determined that the intake of B element decreased under salt stress in both years. Our results showed that Fox 11 and BA 29 rootstocks in Fe and Mn uptake; Fox 11 rootstock in Zn and Cu uptake, and OHxF 97 and OHxF 333 rootstocks in B uptake were noted. In general, Fox 11 and BA 29 rootstocks were found to remove more micronutrients from the soil. [ABSTRACT FROM AUTHOR]
