El objetivo fue determinar el contenido de compuestos bioactivos en el fruto del chile de agua (Capsicum annuum L.), cultivado en macrotúneles con diferentes materiales de cubierta. Plántulas de chile de agua del genotipo &#8220;Ejutla&#8221; fueron cultivadas con acolchado plástico y fertirriego, en macrotúneles con cubiertas de plástico transparente, plástico verde y malla blanca. Cada cubierta correspondió a un tratamiento y el cultivo a cielo abierto fue el testigo. Se utilizó un diseño experimental completamente al azar con tres repeticiones. Las variables respuesta fueron a) climáticas: temperatura, humedad relativa y radiación fotosintéticamente activa integrada (RFAI); b) compuestos bioactivos: fenoles totales, flavonoides y capacidad antioxidante. La temperatura diurna, nocturna y humedad relativa bajo plástico verde aumentaron 28.0, 6.7 y 0.5 % con respecto a campo abierto. La RFAI en campo abierto superó en 28.3 % a los materiales de cubierta. El plástico verde incrementó significativamente la concentración de fenoles totales y capacidad antioxidante, superando al testigo en 489.1 y 39.0 %, respectivamente. La concentración de flavonoides totales de los frutos cultivados en campo abierto fue mayor en al menos 47 % a los materiales de cubierta evaluados. La concentración de fenoles de los frutos de chile de agua y la capacidad antioxidante se incrementan cuando se cultivan en macrotúneles con cubierta de plástico verde.]]></p></abstract>

The objective of this research was to determine the content of bioactive compounds into the fruit of the &#8220;Chile de agua&#8221; (Capsicum annuum L.), grown under macro tunnels with different cover materials. Seedlings of the &#8220;Ejutla&#8221; genotype were planted in soil with plastic mulch and fertigation under macro tunnels using transparent and green plastic covers, and white mesh. Each cover corresponded to a treatment, and the open-air cultivation was the control. The response variables were grouped into a) climatic: temperature, relative humidity and Integrated Photosynthetically Active Radiation (IPAR); b) bioactive compounds: total phenols, flavonoids and antioxidant capacity. The daytime and nighttime temperatures and relative humidity under green plastic cover increased 28.0, 6.7 and 0.5 % with respect to the control. The IPAR in open-air cultivation exceeded the cover materials by 28.3 %. The green plastic significantly increased the concentration of total phenols and antioxidant capacity by 489.1 and 39.0 % with respect to the control. The concentration of total flavonoids of the fruits grown in open-air cultivation was greater than at least 47 % to the cover materials evaluated. The phenols concentration of &#8220;Chile de agua&#8221; fruits and their antioxidant capacity increased when they are grown in macro tunnels with green plastic covers.]]></p></abstract>
