To study the role of Ethanol and Acetaldehyde treatments on the yield and berries quality of three grapevines cultivars, recently introduced to Egypt, a field experiment was designed and implemented. The present experiment involved spraying the grapevines with Ethanol at 3%, 6%, and 9%, and Acetaldehyde at 0.5%, 1.0%, and 1.5% on the yield and berry physical and chemical characteristics of the Superior, Red Globe, and Early Sweet cultivars grown in loamy clay soil, under the conditions of Minia Governorate conditions. The obtained results showed that, spraying the vines of the three cultivars with ethanol and acetaldehyde significantly enhanced the yield/vine, berry physical properties, and berry chemical properties. Specifically, the results indicated that spraying the three cultivars with 9% Ethanol had the greatest impact on yield, while spraying the three cultivars with 1.5% Acetaldehyde was the most effective in improving the physical and chemical characteristics of the berry.
