Salinity Tolerance During Germination and Seedling Growth of Some Lentil (Lens culinaris Medic.) Cultivars

Abstract

Present research was conducted to determine effects of salt concentrations on emergence and seedling development of lentil varieties. Trials were made during the year of 2013 on the laboratory and greenhouse of Selcuk University, Agricultural Faculty. Emergency trial was set up according to “Randomized Plots Design” by two factors and four replications; greenhouse trial was also set up according to “Randomized Plots Design” by two factors and three replications. The lentil varieties; Altın Toprak, Fırat-87, Kafkas, Malazgirt-89, Meyvesi-2001, Seyran-96, Sultan-I, Çağıl, Çiftçi and Özbek were used as material for both of the trials. Effects of the five doses of salt concentrations [0 (control), 30 mM, 60 mM, 90 mM and 120 mM] on the ratio of emergency, speed of emergency, average time for emergency, index of sensibility, length of shoot and root, fresh weight of shoot and root, dry weight of shoot and root, index of salt tolerance were evaluated. Responses of the lentil varieties for salt concentrations were differed. Comparing to the control, all of the investigated characteristics on the lentil genotypes showed significant reduction by depending on the increasing salt level. According to the effects of salt application, the lentil varieties Malazgirt-89, Fırat-87 and Çiftçi were the most tolerance by view of plant dry weights while the lentil varieties Özbek and Seyran-97 were the most sensitive. Consequently, the lentil varieties Malazgirt-89, Fırat-87 and Çiftçi showed high tolerance ratio for the salt application.
