This study was carried out in AL Swaida nursery during 2009 and 2010
seasons to study effect of time and grafting high are on the growth strength of
apple cultivars: Golden delicious، Stark rimson, Starking delicious. Results
showed that Golden de
licious preponderated on the other cultivars in diameter
average (9.06 mm) at 3cm above the grafting area (5cm above soil level). The
study also confirmed that Starking delicious showed significant superiority(p
<0.05) in term of growth strength on the other two cultivars when grafting was
carried at 5cm and 20cm above soil level and the best of leaf area (2862،89cm2)
was observed at 20 cm above the soil level when grafting took place in 31 of
August.
