- ... Water stress differently affects yield and fruit quality in processing tomato, usually depressing crop productivity and improving the overall quality of fruits. These effects are well known but there is still a lack of information on water stress effects upon some endogenous enzymatic activities which can be considered as markers of fruit spoilage. Within them, pectinases and oxidases are the majo ...

- ... Flesh browning caused by mechanical damage is one of the most important disorders during shelf-life of persimmon 'Rojo Brillante', which is an astringent cultivar. Our previous studies have shown that browning manifestation is influenced by the level of astringency of the fruit; the present work studies the implication of polyphenol oxidase activity and total antioxidant capacity. Astringent and n ...
