Inhibition of potato tuber sprouting: a review of the methods employed

Abstract

The potato is a tuberous plant cultivated around the world, its tubers can be conserved for a long time, after having been harvested and without losing its parameters of quality, consumption and processing. There are several treatments that allow delay the appearance of outbreaks as the use of plant hormones these are; abscisic acid, gibberellic acid, Índole acetic acid, ethylene and cytokinins that intervene in the physiological phases of the seed tuber, especially in the dormancy process. External agents such as Chlorpropham, maleic acid hydrazide, essential oils and tannins also play an important role in the inhibition of outbreaks. The plants elabórate compounds that are used to regúlate different physiological processes, among them the one of the generation of shoots, that is why the obtaining of vegetal extracts and the study of their active compounds help to the reduction of the use of chemical products among them the walnut extract that by its compounds alkaloids, flavonoids, coumarins and anthroquinines that are in different parts of the tree block the metabolic and hormonal processes of the tuber allowing to decrease the active growth of the shoots and lengthen the dormancy process. The objective of this article is to review some of the treatments that are used to lengthen the sprouting process of potato seed tubers.
