          Abstract

          El precio de la tuna se reduce significativamente durante agosto y septiembre en el Norte-Centro de México debido a que la cosecha se concentra principalmente en esos meses. El retraso de la cosecha es una alternativa para solucionar este problema y fue el objetivo de esta investigación. Se usaron árboles de nopal tunero del cv. Cristalina de cuatro años de edad. Los tratamientos fueron: 1) dejar el desarrollo normal del primer flujo vegetativo y reproductivo y se consideró como testigo, y 2) inducir un segundo flujo vegetativo y reproductivo. El segundo tratamiento retrasó la cosecha por 45 días, e incrementó el peso y la firmeza del fruto, pero el rendimiento se redujo en un 65% comparado con el testigo. Después de cuatro semanas en almacenamiento, la firmeza y la concentración de materia fueron significativamente mayores en los frutos obtenidos fuera de temporada. No obstante la respuesta positiva del cv. Cristalina al retraso de la cosecha, se requieren estudios adicionales en diferentes ambientes y cultivares de nopal tunero con alto valor comercial.

          Translated abstract

          Cactus pear fruit prices drop significantly during August and September in North-Central Mexico because harvest peak is concentrated on those months. Harvest delay is an option to alleviate this problem and it was the aim of the research conducted. Four-year-old cactus pear trees cv. Cristalina were used in this trial. The treatments were: 1) leaving the normal development of the first vegetative and reproductive flux, which was considered as control, and 2) inducing a second vegetative and reproductive flux. The second treatment set back the harvest by 45 days, increased weight and flesh firmness of fruit, but yield was reduced by 65% compared with control. After four weeks in storage, flesh firmness and dry mass concentration were higher in out of season fruits. It is possible to delay the harvest period of the cv. Cristalina, however, additional research work is needed under different environments and other cactus pear cultivars with high commercial value.
