EFFECT of SOME DORMANCY BREAKING AGENTS ON BUD BEHAVIOUR , VEGETATIVE GROWTH , FRUIT SET AND YIELD OF " CANINO " APRICOT.
"Canino" apricot (Prunus armeniaca L.) fruiting trees were sprayed with different bud dormancy breaking compounds on January 20th at different concentrations. Dormex (hydrogen cyanamide) was sprayed at 1,2 and 3% eash alone , zinc sulphate at 5% and urea at 6% alone or combined with 3% mineral oil.All Dormex concentrations alone or combined with mineral oil increased floral and vegetative bud opening and increased retained fruits and yield as compared with the untreated trees. Moreover, total indoles and total free amino acids in shoot buds were increased by all treatments compared with the control.The highest values were obtained by using Dormex at 3% followed by Dormex at 2% . Also , all experimental treatments increased leaf content of nitrogen(N) , phosphorus(P) and potassium(K) comparing with the control , especially in treatments of Dormex 3% followed by Dormex 3% + mineral oil 3% ; however , urea at 6% alone or mixed by mineral oil 3% did not have reliable effect .The most effective treatment was spraying Dormex at 3% alone , which gave the highest percentage of opend floral and vegetative buds and the highest yield (kg/tree) .
