| Abstract | ||||
| This study was carried out during 2018 and 2019 seasons to investigate the effects of foliar spraying six chemical compounds on some vegetative growth, yield, physical, and chemical characters of the berries. The examined compounds were GA3 at 10 ppm, hydrogen peroxide (H2O2) at 10 mM, salicylic acid at 5%, Mepiquat chloride at 200 ppm, micronutrients (A compound of Fe, Zn, Mn, Mo and B) at 0.1%, and free amino acids at 0.1% sprayed three times during the season. Grapevines treated with either compound increased growth, yield, and fruit quality compared to the control treatment. The best chemical compounds on some vegetative growth characters were GA3, followed by micronutrients, H2O2, and salicylic acid. As for the yield and cluster weight and dimensions, the best of chemical compounds was salicylic acid which significantly surpassed the remaining treatments, followed by micronutrients then Mepiquat chloride (MC) and free amino acids. The corresponding increment percentage for these treatments were found to be 48.24, 33.30, 25.59, and 24.51 % over the control, respectively. The results of the current study suggested that spraying three times with salicylic acid at 5% recorded the best results concerning productivity and quality parameters. | ||||
