Tomato is one of the most important food plants in the world,and its demand is continuously increasing being necessary to extend the commercial period and diminish the postharvest losses.When tomato is stored at low temperatures, it suffers chilling injurycausing economic and effort loss (Kader, 1986). Many studies have been carried in order to understand the mechanism by which this physiological disorder is generated, but many aspects need to be clarified yet. Otherwise, it is clear that the chilling injury depends upon many factors including cultivar, preharvest conditions and chilling temperature-time combination. Tomato cv. “Micro-Tom”is a dwarf tomato widely used as a laboratory model that combines the benefits of studying a specie with economic importance with the short life cycle and small size suitable for a biological model bringing basic and applied sciences together. In addition, tomato
