“…The dry materials were ground and were digested via the dry digestion method. The concentrations of copper (Cu 2+ ), manganese (Mn 2+ ), iron (Fe 2+ ), zinc (Zn 2+ ), calcium (Ca 2+ ), magnesium (Mg 2+ ), potassium (K + ), phosphorus (P) and sodium (Na + ) were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) (Torun et al 2013 ). After determining the ion concentrations, the K + /Na + and Ca 2+ /Na + ratios were calculated.…”

Salinity is one of most significant environmental stresses. Marigold is moderately tolerant to salinity stress. Therefore, in this study, the fresh weights of roots and shoots, rootFW/shootFW ratio, moisture content of shoots, micronutrient and macronutrient concentrations and ratios of K+/Na+ and Ca2+/Na+ in the roots and shoots of marigold were determined under salinity stress. Five salinity treatments (0, 50, 100, 150, and 200 mM NaCl) were maintained. In the current study, salinity affected the biomass of marigold. An increase of more than 100 mM in salt concentrations significantly reduced the shoot fresh weight. Increasing salinity stress increased the ratios of rootFW/shootFW, which were more significant under high salt levels (150 and 200 mM NaCl). Wet basis moisture contents of the shoots were reduced when salinity stress increased above 100 mM. In this study, salinity stress affected micronutrient and macronutrient uptake. Increases in the salt concentration and decreases in the concentration of Cu2+ and Zn2+ in the roots and Mn2+ and Fe2+ in the shoots were significant. Based on an increase in salinity stress, while the Ca2+, Mg2+, and Na+ concentrations increased, the K+ concentration decreased in the roots and shoots. Moreover, the K+/Na+ and Ca2+/Na+ ratios of the roots and shoots were significantly lower than those of the control in all of the salinity treatments. As a result, under increasing salinity stress, the Ca2+, Mg2+, K+, and Na+ uptakes in marigold were significant, revealing the effects of stress.

“…Various plant species respond differently to Fe deficiency in soils (Vose 1982;Awad et al 1994;Tagliavini & Rombola 2001;Chen et al 2018). Cultivated strawberries, Fragaria × ananassa Duch., are among the most sensitive species to Fe-deficiency (Álvarez-Fernández et al 2006;Pestana et al 2011;Alkan Torun et al 2013, 2014. Several studies have reported varied response of large number of strawberry cultivars to Fe deficiency in different growth mediums (Alkan Torun et al 2013, 2014Kafkas et al 2007;Gama et al 2016).…”

Cultivated strawberry has been developed from hybridization between Fragaria chiloensis and F. virginiana. The progenitor species exhibit significant genetic diversity. Growth attributes of progenitor species and their responses to several stress factors have been studied. However, iron-deficiency tolerance (FeDT) of different species have merely been tested under hydroponic conditions. This study evaluated FeDT of 23 genotypes belonging to super-seed collection under hydroponic conditions. Two genotypes (one Fe-deficiency tolerant and one sensitive) were selected from screening experiment and their physiological and morphological mechanisms playing role in FeDT were determined. Plant parameters associated with FeDT, i.e., pH of the growth medium, root Fe reductase activity, total and active Fe concentration of shoot were recorded. The Fe-efficiency of strawberry subspecies varied between 51% and 98%. Fe efficiency values also varied among subspecies. AukeLake and RCP37 belonging to F. chiloensis were highly resistant and sensitive to Fe-deficiency, respectively based on Fe efficiency values. A highly significant relationship was observed between Fe concentration and FeDT of the genotypes. Acidification of nutrient solution and root Fe reductase activity were closely related to high shoot iron concentration. Our findings indicated existence of a close relationship between root uptake and root to shoot translocation of Fe, which ultimately contribute greatly to FeDT among tested strawberry genotypes.
