Mechanical stress of kiwifruit is of major importance since it is directly related to fruit quality and postharvest losses. However, the role of mechanical stress in kiwifruit postharvest metabolism remains poorly explored. The present work characterizes the impact of mechanical stress, applied as compression forces (147.1 N), in 'Hay-ward' kiwifru...

Fruit is constantly challenged by wounding events, inducing accelerated ripening and irreversible metabolic changes. However, cognate mechanisms that regulate this process are little known. To expand our knowledge of ripening metabolism induced by wounding, an artificial-wound global transcriptome investigation combined with metabolite profiling st...

The possible role of an early calcium application via sprays (0.25, 0.5 and 1M CaCl 2) on dormant buds to improve sweet cherry (cv. Ferrovia) fruit quality at harvest was investigated. Fruit quality characteristics were also investigated in response to the age of spurs, the ripening stage, and their interactions. Results indicate that calcium enter...

Sweet cherries, Prunus avium L. (Rosaceae), are gaining importance due to their perenniallity and nutritional attributes beneficial for human health. Interestingly, sweet cherry cultivars exhibit a wide range of phenotypic diversity in important agronomic traits, such as flowering time and defense reactions against pathogens. In this study, whole-g...

The im­pact of ul­tra­vi­o­let-C (UV–C) ir­ra­di­a­tion on sweet cherry fruit was stud­ied. Fol­low­ing har­vest, fruits (cv. Sweet­heart) were ex­posed to dif­fer­ent doses of UV-C (0, 1.2, 3.0 or 6.0 kJ m−2) and then cold stored (0 °C) for 10 days. Treat­ments with UV-C de­layed most ripen­ing fea­tures and re­duced pit­ting symp­toms, par­tic­u­...
