The current study focused on the effect of spraying someplant secondary metabolic byproducts, namely. ethanol andacetaldehyde, as well as their potential use as growth promoters and toimprove vegetative growth, nutritional status, and productivity of threegrape cultivars recently introduced and adapted to the Egyptian climate(Superior, Red Globe, and Early Sweet cvs.). Three concentrations ofeach material were used. Ethanol at 3. 6, and 9% and Acetaldehyde at0.5, 1.0, and 1.5%. The obtained results showed that spraying Ethanolshows more effective rather than spraying Acetaldehyde in thisrespect. Spraying Ethanol at 9% presented the best results. Under theconditions of cultivation in clay soils in Minia Governorate and similarconditions, we recommend by spraying the Superior, Red Globe andEarly Sweet cultivars three times during the season with Ethanol at 9%in order to improve growth, nutritional status and yield quantity.
