Article Citation - WoS: 1Citation - Scopus: 1Genetic Diversity and Population Structure of Faba Bean (vicia Faba) From Turkey(American Society for Horticultural Science, 2016) Göl, Şurhan; Doğanlar, Sami; Frary, AnneFaba bean (Vicia faba L.) is an important food and feed legume because of the nutritional value of its seed protein and starch content, good biomass, and high efficiency nitrogen fixation.This study analyzed the molecular genetic diversity and population structure of 101 Turkish faba bean accessions using simple sequence repeat (SSR) markers.A total of 32 SSR markers yielded 281 loci of which 277 (98.6%) were polymorphic.Mean dissimilarity between genotypes was 0.355, a relatively high value which was expected given faba bean’s large genome and limited breeding history.According to the results, faba bean individuals grouped into three main clusters based on both distance matrix (neighbor-joining algorithm) and model-based (population structure) clustering analyses.Clustering was not correlated with seed size or origin within Turkey.Six cultivars were included in the analysis and showed high genetic diversity compared with the landraces, as expected, given the fact that at least some of the cultivars were bred by hybridization.A total of 47 individuals were selected for the core collection to represent the diversity of Turkish faba bean germplasm.This core set encompasses material adapted to all growing regions and should be a priority for morphological characterization. © 2016, American Society for Horticultural Science.All rights reserved.Article Citation - WoS: 6Citation - Scopus: 8Growth and Uptake of Sodium and Potassium in Broad Bean (vicia Faba L.) Under Salinity Stress(Taylor and Francis Ltd., 2011) Bulut, Fatma; Akıncı, Şener; Eroğlu, Ahmet EminVicia faba L. (broad bean or faba bean), a food crop of worldwide importance, is moderately tolerant of saline conditions, such as are increasingly common in Mediterranean countries and in Turkey. Our objective was to determine the influence of two salinity levels [50 and 100 mM sodium chloride (NaCl)] and two potassium salts, potassium nitrate (KNO3) (N1 and N2) or potassium acetate (CH3COOK) (A1 and A2), on the development of seedlings of two cultivars of broad bean (cvs. Eresen 87 and Filiz 99) grown in pots of perlite under controlled greenhouse conditions. Flame photometer (FP) analysis of tissues from roots, stems, and leaves of 3-month-old seedlings showed significant differences in growth, internodal length, and potassium (K+)/sodium (Na+) ratios. The FP analyses revealed that Na+ was the ion most responsible for inhibition of growth parameters seen in both cultivars and salt treatments. K+ contents were consistently higher in cv. Filiz 99 than in cv. Eresen 87. Possible correlations between these data and the tolerance to salinity of these cultivars are discussed.Article Citation - WoS: 11Citation - Scopus: 15Effects of Humic Acid on Root Development and Nutrient Uptake of Vicia Faba L. (broad Bean) Seedlings Grown Under Aluminum Toxicity(Taylor and Francis Ltd., 2015) Büyükkeskin, Tamer; Akıncı, Şener; Eroğlu, Ahmet EminInteractions of humic acid with development and uptake by seedlings of Vicia faba L., (cv. Eresen 87) grown in conditions of aluminium toxicity have been investigated in pot experiments in a controlled greenhouse environment. The objective of the study was to investigate whether humic acid moderates aluminum toxicity. The seedlings were treated with solutions of aluminum chloride (AlCl3) prepared in Hoagland control nutrient solution (HO) and 50 and100 μM and humic acid + Hoagland (HA) solutions, respectively. The 50 and100 μM HA solutions increased root fresh (RFW) and dry (RDW) weights, where the RFW differed significantly from controls (HO) after statistical evaluation by NCSS (NCSS, Kaysville, Utah) with two-sample T-test range at the 5% level. The results of the current experiment suggested that humic acid had suppressed or counteracted the toxic effect of aluminum (Al3+) on both main and lateral root growth. Humic acid seems to block the effect of Al3+ on nutrient uptake, as tested by atomic absorption spectrophotometry (AAS) and flame photometery (FP). Al3+ content in the roots was significantly decreased by 219% in 50-μM HA and by 49% in 100-μM HA treatments respectively. Potassium (K+), sodium (Na+), and iron (Fe3+) were recorded as the other elements taken up in the greatest amounts among the tested nutrients, in addition to Al3+. Humic acid increased the contents of Na+, K+, manganese (Mn2+), and zinc (Zn2+) significantly in both concentrations of HA treatment compared to controls. The Fe3+ content in the roots decreased, in both treatments of HA, application by 252% and 32% respectively. The reduction in the former was significant.
