Efectos del ácido salicílico en tratamientos pre-cosecha en la calidad del fruto del Finger Lime y su conservación durante el almacenamiento en frío

Abstract

Finger lime (Citrus australasica) es una fruta cítrica exótica poco cultivada en la cuenca mediterránea, por lo tanto, se requieren estrategias que mejoren su adaptación y productividad. Así pues, el objetivo de este trabajo fue evaluar el efecto de tratamientos pre-cosecha con ácido salicílico (AS) a distintas concentraciones (1, 5 y 10 mM) sobre la calidad del finger lime en el momento de la recolección y durante 21 días de conservación refrigerada. Los tratamientos con AS 5 y 10 mM lograron reducir significativamente las pérdidas de peso, la tasa de respiración e incrementaron la firmeza en el momento de la recolección y tras la conservación refrigerada. Además, en los frutos tratados con AS 5 mM se observó una disminución en los sólidos solubles totales y un aumento en la acidez titulable. En cuanto al contenido en fenoles totales y actividad antioxidante total en los frutos tratados con AS 5 mM aumentaron durante la conservación refrigerada. Finalmente, se observó un incremento en el contenido en carotenoides totales en los frutos tratados con AS 5 y 10 en el momento de la recolección. Por lo tanto, los tratamientos pre-cosecha con AS 5 mM podrían ser una estrategia interesante para mantener la calidad del finger lime en post-cosecha.

Finger lime (Citrus australasica) is an exotic citrus fruit not much cultivated in the Mediterranean area, thus this crop requires strategies to enhance its adaptation and yield. Therefore, the aim of this study was to evaluate the effect of pre-harvest treatments with salicylic acid (SA) at different concentrations (1, 5, and 10 mM) on the finger lime quality at harvest and during 21 days of cold storage. Fruits treated with 5 and 10 mM SA showed a decrease in weight loss and respiration rate, meanwhile firmness was increased. Besides, in fruits treated with 5 mM SA were observed a decrease in total soluble solids and an increase in titratable acidity compared to control ones. Also, total phenolic content and total antioxidant activity were increased in fruits treated with 5 mM SA after 21 days of cold storage. Finally, total carotenoid content was increased at harvest in fruits treated with 5 and 10 mM SA. Therefore, pre-harvest treatments with 5 mM SA could be an interesting strategy to maintain the post-harvest fruit quality of finger lime.
