| description | Tomato and potato crops are agricultural products of great importance worldwide due to their nutritional and industrial value. The distribution of photoassimilates in the sink organs of these crops depends to a great extent on the metabolism and partition of carbon generated in the photosynthetic processes, on the dynamics of both of the source and sink organs as the activity of enzymes linked to the metabolism of sugars and environmental and nutritional conditions. The objective of this paper was to review and discuss current knowledge of the distribution of photoassimilates in the sink organs and factors that can affect this mechanism in the tomato and potato crops. Based on information collected in recent research and review articles, it is reported that around 80% or 90% of the photoassimilates produced in the source organs in tomato and potato crops are transported or translocated to the sink organs of commercial interest (fruits and tubers). Both source/sink imbalance, as well as water stress and nutritional deficiencies, especially nitrogen and potassium significantly affect the distribution of photoassimilates. In contrast to the effects of the quality of light, it can improve the loading of photoassimilates in the sink organs and improve quality attributes of these such as increases in the size and concentration of sugars. However, more research is still needed to corroborate this effect, especially under field or greenhouse conditions in tropical regions. |

Los cultivos de tomate y papa son productos agrícolas de gran importancia a nivel mundial por su valor nutricional e industrial. La distribución de fotoasimilados en los órganos vertederos de estos cultivos depende en gran medida del metabolismo y partición de carbono generado en los procesos fotosintéticos, en la dinámica tanto de los órganos fuente y vertedero como en la actividad de enzimas vinculadas al metabolismo de azúcares, así como factores ambientales y nutricionales. Basado en esto, el objetivo de este documento fue revisar y discutir sobre el conocimiento actual de la distribución de los fotoasimilados en los órganos vertederos y los factores que pueden afectar este mecanismo en los cultivos de tomate y papa. De acuerdo con la información recopilada en artículos de investigación y de revisión recientes, se reporta que alrededor del 80% o 90% de los fotoasimilados producidos en los órganos fuentes en los cultivos de tomate y papa son transportados o translocados hacia los órganos vertederos de interés comercial (frutos y tubérculos). Tanto el desbalance en fuente/vertedero, así como el estrés hídrico y nutricional, en especial, deficiencias de nitrógeno y potasio afectan significativamente la distribución y transporte de los fotoasimilados. En contraste con los efectos de la calidad de la luz puede mejorar la carga de fotoasimilados en los órganos vertederos y mejorar atributos de la calidad como aumento en el tamaño de los frutos y concentración de azucares. Sin embargo, aún faltan más investigaciones que corrobore este efecto bajo condiciones de campo o en invernadero en las condiciones del trópico.
