تعیین مناسبترین زمان و روش پیوند برای چیکو روی پایه کرول در استان هرمزگان

The experiment was carried out for 2 years (April 2001- June2003) at Minab Agricultural Research Station to find the most suitable grafting time and method for Chiku (Achras sapota L.) onto Kerul (Manilkara hexandra L.) seedlings under Hormozgan condition .The RCBD was used with 2 factors, 12 times on the 15th and 30ieth of each month from Farvardin 15th to Ordibehesht 30ieth and Shahrivar 15th to Azar 30ieth as the first factor and 2 methods of grafting including inarching and veneer as second factor in 3 replication. The percentage of graft sprouting(callus production and apical bud sprouting) and graft success (good union with growth)were measured after 90 and 180 days respectively. There were significant differences (L=5%, Dunmrt) between inarching (68.45%) and veneer (78.32%) on graft sprouting and no significant differences on graft succes, 63.66% and 61.71% respectively. The best times for inarching is Farvardin 15th, Farvardin 30ieth and Shahrivar 15th and for veneer is Farvardin 15th (93.40%succ.) , Farvardin 30ieth, Shahrivar 30ieth and Mehr 15th.
