| Abstract | ||||
| THIS STUDY was carried out during 2013 and 2014 seasons to test the effect of spraying royal jelly, arginine or tryptophane each at 0.025 to 0.1% three times on growth , plant pigments, leaf N, P, K and Mg, yield and fruit quality of Superior grapevines.Three sprays of royal jelly, arginine, tryptophane each at 0.025 to 0.1% resulted in an obvious promotion on all growth traits, plant pigments and leaf content of N, P, K and Mg , yield as well as physical and chemical characteristics of the berries relative to the control treatment. The promotion was materially related to the increase in concentrations of the three stimulants. Increasing concentration from each stimulant from 0.05 to 0.1% had no significant promotion on these characters. The best results were obtained due to using royal jelly, arginine and tryptophane, in descending order. Carrying out three sprays of royal jelly at 0.05% to Superior grapevines resulted in the best results with regard to yield and quality of the berries. | ||||
