Propuesta de estrategia para la sincronización de la floración entre progenitores de caña de azúcar en el centro de Cuba.

The poor flowering and the differences in the date of exit of the flower in commercial varieties of sugar cane at Guayos's locality make hard the realization of crossbreedings, which is why objective of this work is to propose a strategy that it enable to increase them. Several experiments, that they executed themselves in areas of the seat of the National Center of Hybridization, located in Guayos got on for it and included two dates of plantation, two dose of fertilizers, two methods of sheets, use of irrigation and Ethrel in the inductive stage and Fitomás-E, in the stage after inductive of the flower. You used a control with the methodology in use of handling of the flower for this locality for all of the cases, and they measured the bloomed varieties, intensity of flowering and date or days to start of flowering, the one with which an analysis of variance was used and when it was significant the stockings through Tukey's proof compared . As a result it was found that flowering increased in with use irrigation, than the Fitomás-E you advanced the date of exit of the flower, in the meantime than July's and January's plantations, the cut of sheets, the application of Ethrel and of fertilizers, you delay it. These combined results can be used to enlarge the time of flowering and served as base stops a strategy that it enables proposes the quantity of crossbreedings at Guayos's locality increasing.
