Mineral Composition of Leaves and Fruits of Some Promising Jujube (Zizyphus jujuba Miller) Genotypes

Abstract

The mineral compositions of leaves and fruits of the 4 selected promising jujube genotypes were investigated. Nitrogen, potassium, calcium and magnesium for leaves and nitrogen, potassium and calcium for fruit were major macroelements in promising jujube genotypes and represented about 98 and 93 % of the total mineral content, respectively. Other minerals were also detected in appreciable amount in leaves and fruits. Significant differences were observed for each individual mineral between genotypes except for the sodium content in leaves and manganese content in fruits. Generally, it was determined that jujube genotypes have high content of the minerals. Jujube genotypes are rich based on calcium, potassium, magnesium, sodium and phosphorus.
