Abstract
This investigation was carried out on Valencia orange (Citrus sinensis L. Osbeck) trees budded on three citrus rootstocks in a private orchard at El-Bostan, El-Behiera Governorate during two successive seasons of 2005 and 2006.The considered rootstocks were: Volkamer lemon (Citrus volkameriana, Tan & Pasq.), Rangpur lime ( Citrus limonia Osbeck ) and Sour orange (Citrus aurantium linn.).
The data revealed that Valencia orange grafted on Volkamer lemon produced the highest trees with more canopy diameter, volume, trunk circumference of rootstock and scion than those obtained from trees budded on Rangpur lime or Sour orange. Furthermore, trees grafted on Volkamer lemon gave a longer shoots with more number of leaves per shoot and leaf area than those obtained from Rangpur lime or Sour orange rootstocks.
Valencia orange trees budded on Volkamer lemon gave higher yield and fruit weight than trees budded on Rangpur lime or Sour orange. Whereas, trees budded on Sour orange presented a lower yield with higher SSC and total acidity than those obtained from Valencia orange fruits budded on Rangpur lime or Volkamer lemon. Whereas, Rangpur lime produced fruits with higher Vitamin C in fruit juice than the other rootstocks.
