          Abstract

          Resumen La demanda de frutas exóticas, entre ellas la uchuva, se ha venido incrementando debido a sus excelentes propiedades nutricionales y sus altos contenidos de vitaminas A, B y C y de minerales como el calcio, el hierro y el fósforo, ideales para fortalecer el sistema inmunitario. Los frutos de la uchuva tienden a rajarse, por lo que debe suministrárseles agua en cantidades adecuadas. No se conoce el efecto de dicho riego bajo condiciones de invernadero, por lo que se evaluó su manejo en el marco de un diseño completamente al azar utilizando cuatro láminas de riego (0,7, 0,9, 1,1 y 1,3 de la evaporación del tanque de clase A) y nueve repeticiones, es decir, 36 unidades experimentales. Las plantas se cultivaron en materas de 20 L con sustrato de turba rubia. Con la lámina de riego de 1,3 se obtuvo el mayor número de frutos y la mayor producción por planta a partir de la tercera recolección quincenal en el ciclo de las cosechas. La producción en invernadero fue menor cuando las plantas se sometieron a estrés hídrico (láminas de riego de 0,7 y 0,9) y debido a las altas temperaturas bajo cubierta. En las últimas cosechas la cantidad de frutos pequeños fue la más abundante. La relación entre cáliz y fruto aumentó conforme avanzó el ciclo de las cosechas. Independientemente de la lámina de riego, cuanto mayor era el tamaño del fruto, mayor la incidencia del rajado.

          Abstract The demand for exotic fruits has been increasing due to their excellent nutritional properties. One of these is the Cape gooseberry, which has high contents of vitamins A, B, and C, as well as minerals such as calcium, iron, and phosphorous, ideal for strengthening the immune system. Cape gooseberry fruits tend to crack and, therefore, they must have an adequate supply of water. However, the effect of water supply on their production in greenhouse conditions during the harvest periods is not well known. Given the importance of irrigation management to produce Cape gooseberries, we used four irrigation levels in a completely randomized design (0.7, 0.9, 1.1, or 1.3 of the evaporation of a class A tank) with nine repetitions representing 36 experimental units. Plants were grown in 20 L pots using blonde peat as a substrate. The irrigation level of 1.3 generated the highest number of fruits and the highest production per plant as from the third biweekly harvest. The production decreased when the plants were subjected to water stress (water levels of 0.7 and 0.9) under the high temperatures of protected cultivation. In the last harvests, small fruits were the most abundant. The calyx/fruit ratio increased as the harvest cycles progressed. Regardless of the irrigation level, the larger the fruit, the greater the incidence of its cracking.

          Climate resilient crops for improving global food security and safety.

          Food security and the protection of the environment are urgent issues for global society, particularly with the uncertainties of climate change. Changing climate is predicted to have a wide range of negative impacts on plant physiology metabolism, soil fertility and carbon sequestration, microbial activity and diversity that will limit plant growth and productivity, and ultimately food production. Ensuring global food security and food safety will require an intensive research effort across the food chain, starting with crop production and the nutritional quality of the food products. Much uncertainty remains concerning the resilience of plants, soils, and associated microbes to climate change. Intensive efforts are currently underway to improve crop yields with lower input requirements and enhance the sustainability of yield through improved biotic and abiotic stress tolerance traits. In addition, significant efforts are focused on gaining a better understanding of the root/soil interface and associated microbiomes, as well as enhancing soil properties.
