Abstract
This study was carried out for two successive seasons (2013&2014) in a private vineyard located at Aga – Dakahlia Governrate to evaluate the efficiency of some new alternatives on dormancy breaking of Flame Seedless grapevines. The chosen vines were 5 years old, grown in a clay loam soil, spaced at 2x2.5m , irrigated by flood irrigation system .The vines were pruned during the second week of January for the two seasons of the study to obtain bud load of 72 buds/vine (6 canes x 12 buds/cane)and sprayed on the third week of January by phosphoric acid 2%, sulphoric acid 2%, potassium nitrate 5%, potassium hydroxid 1%, zinc sulfate3%, urea10%, H2O2 1%, dormex 4% and mineral oil7%. The result show that all treatments hastened the beginning of bud burst and significantly shortened the duration of bud burst rather than the control treatment. Dormex at 4% was most effective as it gave about 95% bud burst.
