Abstract
This investigation was carried out in 1997 and 1998 seasons on 2 and 3-year old Washington Navel orange. Valencia orange and Balady mandarin budlings on five Citrus rootstocks namely; C.volkameriana, Troyer citrange, Rangpur lime, Cleopatra mandarin and sour orange grown at the Experimental Farm of Sakha Agricultural Research Station, Kafr EI-Sheikh. Egypt where the soil is slightly saline alkaline clayey soil. The evaluation results indicated that Valencia, Washington Navel oranges and Balady mandarin as scion varieties on C'.volkaneriana and Rangpur lime rootstocks are characterized by: Higher leaf concentrations of N, K, Ca, Mg, Fe, and Zn, lower C N, N/K and higher K Na ratio compared to other rootstocks while, leaf P and Mn showed no consistent trend. Moreover, these rootstocks had higher ability to reduce Na- and CI absorption and its accumulation in leaves of the three scion varieties in contrast to the other rootstocks. Also, they had the least values of leaf miners infection. Generally, the five tested rootstocks could be descendingly arranged due to their effects on these characters of the three scion varieties (WO, VO and BM) under this study conditions as follow: (VM & RL), (TC & SO) and finally (CM). Accordingly, both rootstocks (VM & RL) may be considered as suitable substitutes for sour orange in Egypt. This evaluation couid be of great value for nurserymen and citrus growers. It help growers to select the right rootstock for the desired variety in a given area.
