Bread Wheat Responds Salt Stress Better Than Einkorn Wheat Does During Germination, Di̇dem Aslan, Nusret Zenci̇rci̇, Murat Etöz, Bülent Ordu, Sara Bataw
Turkish Journal of Agriculture and Forestry
Salt stress during germination degenerates crop establishment and declines yield in wheat (Triticum subsp.). Against salt (NaCl) stress, we investigated 12 bread (Triticum aestivum L.) and 10 einkorn wheat (T. monococcum subsp. monococcum) entries for germination rate, germinating power, coleoptile length, shoot length, root length, shoot/root length ratio, root fresh weight, root dry weight, and root fresh/dry weigh ratio. An effective blocking in variance analysis improved statistical significance and differentiation between germination stages and wheat entries. Salt total and salt ranking tolerance indices grouped the wheat entries into tolerant (Bayraktar 2000, Gerek 79, İkizce 96, Gün 91, Demir 2000, and …
