Due to the problems presented by the tempered climate fruit trees -in particular the case of apple trees- under the presence of benign winters it becomes necessary the usage of forced production techniques that diminish the effects caused by the lack of cold. In this work a new methodology named pulsing was evaluated. Two stimulating products for bud breaking were applied, the first one Revent (Thidiazuron) and the second one Dormex (Hydrogenated Cianamida), in addition to a defoliant experimental product of the com pany GBM (Copper Fulvate); using different doses, as well as 2 dates of application of individual and combined products. The studied variables were: percentage of bud breaking and the yield, finding highly significant differences between treatments. On the basis of the obtained results, the best applications increase the bud breaking between 183 % and 245 %. For the yield, the increases ranked from 517 % to 884 %, as compared with the commercial witness, used traditionally in the region of Arteaga, Coah., México.
