Sweet potato (Ipomoea batatas L.) is an important food crop around the world, being cultivated in more than 100 countries as the crop can be a rich source of energy and have been recognized as healthy foods because of their significant content of phytonutrients. In recent years, the use of bioregulators in sustainable agriculture has been growing because it leads to higher content of nutrients in the plant tissues and positive metabolic changes. It appears that using abscisic acid in controlling the mechanisms of plant evolution is a good alternative for an ecologic agriculture given that recent studies on the mechanism of the abscisic acid action have shown its great importance as a bioregulator for plants. The objective of this work was to to study the influence of the abscisic acid treatment on some quality characteristics of sweet potato. For this purpose abscisic acid solutions in different concentrations were used as foliar treatments on sweet potato leaves and comparative results concerning some morphological and biochemical changes in the tuberous roots were studied. The experiment was conducted starting with the first leaves appearance until the harvesting of the roots, while determination of the sugars and proteins content were made on the tuberous root harvested in the maturity stage.
