Effect of calcium applications on ion accumulation in different organs of pepper plant under salt stress

Abstract

The present study was carried out in a climate chamber and water culture of physiology laboratory of Van Yüzüncü Yıl University, Faculty of Agriculture, Department of Horticulture. Demre pepper varieties are used in the study of different levels of calcium (Ca) morphological and biochemical effects of pepper plants under salt stress were investigated. The study was carried out in 16/8 hour light / dark photoperiod, 25 oC and % 70 humid climate chamber in controlled conditions. In order to determine the biochemical changes occurring in stressed plants, the amount of ions Na, K, Ca, Cl in root, stem and leaves of plants and Ca/Na ratio were determined. The accumulation of Na and Cl ions was found to decrease in root, stem and leaves as the dose of Ca increased. It can be said that increasing doses of Ca applications under salt stress are partially effective in reducing the negative effects of salt.
