Resumen


El estudio se realizó para determinar el efecto de la intensidad de la caída de los racimos en las características de las avellanas, los compuestos bioactivos y la composición de ácidos grasos en cultivares de avellanas Tombul, Palaz y Kalınkara. La caída del racimo afectó significativamente a la composición de bioactivos y ácidos grasos, mientras que no afectó a las características de la avellana. A medida que aumentaba la intensidad de la caída de los racimos, aumentaban los compuestos bioactivos en todos los cultivares. La fuerte intensidad de caída de los racimos determinó que los fenoles totales, los flavonoides totales y la actividad antioxidante fueran más altos. Excepto para el cultivar Kalınkara, con un bajo contenido de ácido linoleico, un alto contenido de los ácidos oleico y esteárico se determinó en una ligera intensidad de caída de racimos. A medida que aumentaba la intensidad de la caída de los racimos, aumentaba el ácido palmítico. El análisis de componentes principales mostró que la intensidad de caída leve e intermedia generalmente se agrupaba con la longitud del grano, los ácidos oleico, linoleico, esteárico, palmitoleico, 11-eicosenoico y araquídico. En contraste, la intensidad fuerte se agrupó con el peso de la avellana y el grano, la proporción del grano, el ancho del grano, el grosor del grano, el tamaño del grano, los compuestos bioactivos y el ácido palmítico. Como resultado, la composición de compuestos bioactivos y ácidos grasos, que es eficaz para la salud humana, se vio significativamente afectada por la intensidad de la caída del grupo.
