Effect of Some Selected Candidate Wild Plum Rootstocks on Uptake of Some Macro Nutrients of Apricot Varieties

Abstract

This study was conducted at East Mediterranean Transitional Zone Agricultural Research Institute between 2013 and 2015 to determine some macro nutrient contents of apricot varieties grafted on some wild plum genotypes collected by selection from natural environment of Kahramanmaraş. In the study, Myrobolan 29C and GF 677 standard plum rootstocks were used as controls with a total of 9 selected clone rootstock specimens; three from Prunus spinosa, Prunus domestica and Prunus divaricata as rootstocks; and Hacıhaliloğlu, Kabaaşı and Hasanbey apricot varieties were used as grafting material. As a result of the research; it was found that the total nitrogen content of apricot leaves varied between 2.43-3.02%, the phosphorus contents varied between 0.13-0.18%, the potassium contents varied between 2.21-3.20%, the calcium contents varied between 1.67-1.98% and the magnesium contents varied between 0.29-0.54%. It has been determined that these values obtained are in accordance with the reference values and, there is no deficiency in the apricot plants due to the plant nutrients examined.
