بررسی و انتخاب مناسبترین فاصله کاشت پرتقال رقم تامسون ناول بر روی پایه فلایینگ دراگون

Flying Dragon is a dwarfing citrus rootstock and use of this rootstock in high density can increase yield. This study was established to answer the question ; What is the best distancees between trees to rech the highest performance? As a Completely Randomised Block Design. The study consists of 4 tretments ( 22ا , 2ا3 , 2ا4 & 2ا5 ) and 3 replications. Each treatment conclude 9 trees. All rootstocks were propagated by cutting to have enough uniformity. Produced rootstocks under mist system in june 1998 were budded with Thomson Navel orange scions in spring 1999. Trees were planted according to the designed treatments in early spring 2000. Vegetative parameters consist of : canopy volume , stem diameter at 10 centimeter bove bud union and height of trees were measured to 3 years. Data were analysed by MSTATC software. Results shows no significant differences between treatments for any ofmeasured parameters.
