Effect of time and grafting high area on the growth strength of apple cultivars: Golden Stark rimso and Starking delicious،delicious

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 delicious 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.
