    Biochemical Diversity and Antioxidant Potential of Wild Chives (Allium Schoenoprasum L.) Accessions
    (Academic Press, 2025) Cakmakci, O.; Sensoy, S.; Eroğlu, H.
    This study investigated the biochemical diversity of chive (Allium schoenoprasum L.) accessions collected from Van Province, Türkiye, and compared them with selected Allium species (Allium vineale, Allium schoenoprasum var. sibiricum, and Allium tuberosum). The analyses focused on key biochemical traits, including total phenolic content, antioxidant capacity, radical scavenging activity, activities of antioxidant enzymes (superoxide dismutase, catalase, and ascorbate peroxidase), lipid peroxidation, and phenolic compound profiles (quercetin, myricetin, rutin, chlorogenic acid, and quinic acid). Significant biochemical variability was detected among the A. schoenoprasum accessions. Notably, accession A6 exhibited the highest total phenolic content (61.2 g GAE kg-1) and antioxidant capacity (139.89 mmol Trolox equivalents kg-1). Accession A2 showed the greatest superoxide dismutase (24.63 U g-1 FW) and catalase (25.66 U g-1 FW) activities, whereas accession A3 was distinguished by its elevated myricetin concentration. Higher rutin contents were observed in accessions A1 and A2. Hierarchical cluster analysis revealed that A. schoenoprasum accessions formed a distinct cluster, with A. vineale grouping more closely with them than with the other Allium species. Correlation analysis demonstrated strong positive associations between total phenolic content, antioxidant capacity, and individual flavonoid concentrations. Overall, these results highlight the substantial genetic potential of wild A. schoenoprasum accessions from Van Province as valuable genetic resources for Allium breeding programs and as promising natural antioxidant sources for food and pharmaceutical industries. © Articles by the authors; Licensee UASVM and SHST, Cluj-Napoca, Romania.

    Growth Performance of 'granny Smith' and 'fuji Cultivars Grafted Onto Dwarf Rootstocks: a Preliminary Study in Eastern Anatolia
    (Academic Press, 2011) Oǧuz, H.I.; Mtaş, T.; Muradoǧlu, F.
    This study was carried out to determine the growth performance of 'Granny Smith' and 'Fuji' apple varieties, which are widley grown in Turkey, grafted to dwarf rootstocks within their initial two years under continental ecological conditions of the Van Region in East Anatolia. In the first year, the vegetative characters of the cultivars were measured, whereas the yield and the growth rate were both determined in the second year. The yields of 'Granny Smith' and 'Fuji' varieties were 2.38 and 3.88 kg, with average fruit weights of 173.71 g and 136.76 g, respectively. The concentrations of soluble solids, an important quality attribute, were 11.2% and 12.9% for 'Granny Smith' and 'Fuji', respectively. Titratable acidity, which indicates the maturity of the fruit and specifies the market suitability, was found to be 0.37% in 'Granny Smith' and 0.52% in 'Fuji'. Although some properties differed between these cultivars, the firmness of both cultivars was the same, with a value of 6.6 libre. Although both varieties have a double sigmoid vegetative growth, 'Granny Smith's vegetative growth was relatively better than that of 'Fuji', whereas 'Fuji' had a higher productivity. However, for precise evaluation of yields, the period of economical production is required. Preliminary results of morphological, phenological, and pomological tests showed that the varieties 'Granny Smith' and 'Fuji' grafted onto dwarf rootstocks have a potential for increased production in the Van region of Eastern Turkey.
