| Abstract: | The effects of urea and calcium chloride and their combinations on qualitative and quantitative characteristics of pomegranate fruits were studied over 2 years. Aqueous solutions of urea at 0%, 0.5%, 1% and 2% and calcium chloride at 0%, 2% and 4% were applied on two branches of pomegranate (Punica granatum L. cv Malase-Yazdi) at full bloom (FB) and 1 month after full bloom (1MAFB) stages. Urea at concentrations of 1% and 2% significantly increased aril size, fruit length and diameter. Calcium chloride at concentrations of 2% and 4% significantly increased average fruit weight and ascorbic acid (AA) content. Both urea and calcium chloride increased soluble solid content (SSC) at all of the used concentrations. In the first time of spraying, higher level of treatments reduced titratable acidity (TA), but the second time of spraying did not significantly affect the TA. |
