We studied the effects of interstocks in dwarfing properties and photosynthesis ratio during the growth period. Combinations were set up by grafting ‘Navelina’ orange (N) and ‘Kütdiken’ lemon (K) cultivars grafted on sour orange; and, Flying Dragon trifoliate (FD), Citrumelo 1452 (C), Star Ruby grapefruit (SR), Rubidoux trifoliate (R) were used as interstock. Experimental plants were grown in controlled greenhouses. Rootstock, interstock and scion stem diameters and sprout growth were measured following grafting on a monthly bases. Aboveground parts of plants, leaf and root dry weight, number of leaves, leaf area, photosynthesis rate and transpiration ratio were determined on plants at four periods (July 06, October 06, January 07 and April 07). The greatest dwarfness effect determined at final measurement of various grafting combinations was at FD interstock for ‘Naveline’ orange and at R interstock for ‘Kütdiken’ lemon. The highest dry weight of aboveground parts of plants for both cultivars was determined at C interstock combinations and control, whereas lowest values were determined at SR interstock combinations. The photosyhthesis rate was highest in summer period. The photosynthesis rate was highest at ‘Navelina’ cultivar having dwarfing effect at N/FD/SO and N/SR/SO combinations while the highest photosynthesis rate for ‘Kütdiken’ was achieved at K/C/SO combinations, which has no dwarfing effect
