It was aimed to investigate effect of water salinity on M.M. 106 and Pyrus communis rootstocks to the response of the nutritional status. In this regard nutritional status (leaf, N, P, K, Ca, Mg, Fe, Mn, Zn and Na contents) in response to the included treatments of experiments were investigated. Data obtained revealed that the interaction between soil kind; salinity levels; sodium adsorption ratio and chloride level (Cl: SO4 ratio) was obviously detected. Regarding to leaf mineral composition, the irrigated M.M.106 and Pyrus communis rootstocks transplants grown in sandy soil with the highest concentration saline solution (6000 ppm) of higher SAR (6) and Cl: SO4 ratio had the richest leaves in their Ca and Na contents associated with the least levels of N, P, K, Mg, Fe, Mn and Zn. The trend took the other way around with control (continuously irrigated transplants with tap water) followed by those supplied with 2000 ppm saline solution of lower SAR (3) and lower Cl: SO4 ratio where the least values of leaf Ca and Na contents with the higher N, P, K, Mg, Fe, Mn and Zn contents were recorded especially M.M.106 and Pyrus communis rootstocks transplants grown in clay soil. |
