    Effect of Salt Stress on Some Growth and Physiological Parameters of Peanut (Arachis Hypogea L.) Varieties
    (Centenary University, 2021) Yolcı, M.S.; Tunçtürk, R.; Tunçtürk, M.
    In this study, the effects of salt stress (0, 100, 200 mM NaCl) on some growth and physiological parameters of peanut (Arachis hypogea L.) cultivars (Arıoğlu-2003 and Gazipaşa) were investigated. The experiment was carried out as a factorial experiment based on completely randomized design with 3 replicates under controlled growth chamber. As a result of the research; The effect of salt stress on shoot length, root fresh and dry weight was statistically insignificant. Increasing salt concentrations, while increasing ion leakage in leaf tissues, leaf temperature and malonyldialdehyde (MDA) level, it decreased other growth and physiological parameters. In the study; maximum root length (29.2 cm), shoot fresh weight (8.67 g), shoot dry weight (2.88 g), relative water content in leaf tissues (56.6%), membrane resistance index in leaf tissues (79.7%), leaf area (17.6%) and chlorophyll ratio (66.3) were obtained from control (0 mM NaCl) applications, while the highest ion leakage in leaf tissues (61.4%), leaf temperature (19.3 0C) and MDA level (0.464 nmol g-1) were determined from 200 mM NaCl applications. In addition, statistically significant differences were found among the varieties on other parameters except shoot length, root fresh and dry weight, and it was determined that Gazipaşa peanut variety was partially more resistant to salt stress than Arıoğlu-2003 variety. © 2021, Centenary University.
