“…The pH of tomatoes stored at 7 and 22 °C did not significantly changed (p > 0.05); while at 37 °C, the pH was increased (p < 0.05). Gómez and Camelo (2002) reported that during the storage of tomatoes in controlled atmosphere (12 °C), the pH slightly increased. In general, the titratable acidity was 0.3 ± 0.0% (citric acid), and was under the reported by other researchers, like Wold et al (2004); they informed a titratable acidity of 0.44-0.77%.…”

Tomato is one of the most important crops at worldwide; however, much of the production is lost during the postharvest due to the inadequate storage conditions. The aim of this study was to evaluate the effects of different postharvest conditions on some quality and bioactive parameters of tomatoes. Tomatoes Roma VF variety were stored at three temperature (7, 22, and 37 °C) to evaluate some physicochemical characteristics (pH, total soluble solids, titratable acidity, color, and firmness) and bioactive compounds (vitamin C, lycopene, carotenoids, and antioxidant activity) during five days; time in which tomato change from physiological to edible maturity. The a color parameter increased significantly (p < 0.05) at the storage temperature of 22 and 37 °C. The firmness was higher in tomato stored at 7 °C after 5 days, while at 37 °C the firmness decrease in 8%. Tomatoes stored at 22 °C showed a decrease of chlorophyll a and b, reaching the maximum lycopene (31.7 ± 1.5 mg/kg fresh weight) and carotenoids contents (118.7 ± 0.1 μg/100 g fresh weight), while at 7 and 37 °C the chlorophyll a did not change during the storage. However, the vitamin C was higher in tomatoes stored at 7 and 37 °C. The antioxidant activity remains constant during the time of storage, regardless the temperature. The storage temperature of 22 °C not affected significantly (p < 0.05) the color and firmness of tomatoes, at the same temperature, the bioactive compounds (carotenoid, vitamin C, and antioxidant activity) presented highly correlated with the developments of the red color.

“…Of the soluble solids, approximately 60% are sugars, mainly glucose and fructose (Gómez and Camelo, 2002), since the plant is highly necessary an adequate supply of these, nutrition and management are very important to achieve this goal (Reuscher et al, 2014). Among other important factors, nutrition is essential for an adequate concentration of °Brix in marketable fruits.…”

“…El sistema de riego utilizado fue por goteo automatizado, entre planta y planta se colocó un gotero autocompensado cuyo gasto es de 3 L h -1 unido a un distribuidor de cuatro postharvest handling, Gómez and Camelo (2002) and even fruit coatings Amaya et al (2009). Likewise, the content of lycopene in tomato fruit is important because it is a carotenoid that, because of its antioxidant capacity, protects cells from oxidation by the free radicals present in the body, which helps prevent diseases such as cancer, cardiovascular problems and accelerated aging (Ordoñez et al, 2009).…”

“…It is important to note that variations between quality in tomato fruits are due to many factors such as: the production system regarding hydroponics and soil, Arana et al (2006); Casierra and Aguilar (2008);genotype, Hernandez et al(2013); López et al (2015), the dose in the potassium nutrition, Bugarin et al(2002a); Ramírez et al (2011); the organically or mineral fertilizer, Cano et al(2004), Rodríguez et al (2009);Márquez et al (2013): foliar applications of organic compounds, Arteaga et al (2006); Terry and Ruiz (2010); climate regarding planting season, Gaspar et al (2012); irrigation, Fortes et al (2013), de compuestos orgánicos, Arteaga et al (2006); Terry y Ruiz (2010; el clima respecto a temporada de siembra, Gaspar et al (2012), el riego, Fortes et al (2013), el manejo postcosecha, Gómez y Camelo (2002) e incluso los recubrimientos al fruto Amaya et al (2009). De igual manera es importante el contenido de licopeno en fruto de tomate debido a que es un carotenoide que por su capacidad antioxidante protege a las células de la oxidación por los radicales libres presentes en el organismo, lo que ayuda a prevenir enfermedades como el cáncer, problemas cardiovasculares y envejecimiento acelerado (Ordoñez et al, 2009).…”

ResumenEl rendimiento y calidad en la producción de tomate es de suma importancia para los productores que se dedican a esta actividad. El objetivo de esta investigación fue el estudio del efecto de fertilizantes foliares en el incremento del rendimiento y parámetros de calidad de tomate (Solanum lycopersicum Mill.) en condiciones de hidroponia bajo invernadero. Durante 2015, se realizó un experimento en un invernadero del Posgrado en Hidrociencias del Colegio de Postgraduados-Campus Montecillo bajo un diseño bifactorial con dos híbridos de tomate indeterminado tipo Saladette "Cid" y "Azhura" y tres fertilizantes foliares comerciales foligral ® , nutri K-80 ® y nutri humus ® y un testigo. Así se generaron ocho tratamientos con cuatro repeticiones. El sistema de riego fue por goteo para fertirrigación con solución Steiner a una conductividad máxima de 2.5 dS m -1. Se cuantificó el consumo hídrico durante el ciclo de cultivo, se evaluaron el rendimiento total y algunas variables de calidad como: el contenido de solidos solubles (°Brix), licopeno y potasio en fruto. El consumo hídrico estimado en el experimento fue alto y la eficiencia del uso del agua fue baja. No se presentaron diferencias significativas entre los dos genotipos evaluados; sin embargo, la aplicación AbstractThe yield and quality in the production of tomatoes is of paramount importance for the producers that dedicate themselves to this activity. The aim of this research was to study the effect of foliar fertilizers on increasing yield and quality parameters of tomato (Solanum lycopersicum Mill.) under hydroponics in greenhouses. During 2015, an experiment was carried out in a greenhouse of the Posgraduate in Hydrosciences of the College of Postgraduates-Montecillo Campus under a bifactorial design with two indeterminate tomatoes type Saladette "Cid" and "Azhura" and three commercial leaf fertilizers foligral ® , nutri K-80 ® and nutri humus ® and a witness. Thus eight treatments were generated with four replicates. The irrigation system was drip fertigation with Steiner solution for a maximum conductivity of 2.5 dS m -1 . The water consumption was quantified during the growing cycle, the total yield and some quality variables were evaluated as the content of soluble solids (°Brix), lycopene and potassium in fruit. The water consumption estimated in the experiment was high and the water use efficiency was low. There were no significant differences between the two genotypes evaluated; however, the application of foliar fertilizers IntroducciónEl cultivo de tomate es una hortaliza que se cultiva en grandes extensiones, de las cuales se obtienen importantes volúmenes de producción y que además participa de manera importante en la economía internacional, aspecto que no podría lograrse sin calidad del fruto; lograda en gran forma mediante la correcta nutrición y en particular por la aplicación de fuentes potásicas al cultivo. En el año 2013 se generó un valor de $8 803 millones de dólares en el comercio internacional de tomate; mismo del que México part...
