MORALES PEREZ, Aaran Aquilino; FRANCO-MORA, Omar; CASTANEDA-VILDOLZOLA, Álvaro  e  MORALES-ROSALES, Edgar Jesús. Effect of resveratrol in cherimoyas under a transport simulation. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.1, pp.127-132. ISSN 2007-0934.

Once harvested, the cherimoya fruit matures for consumption in 3 to 7 days; during this period, it softens and is damaged by the post-harvest handling and transport. Resveratrol (RVS) has been shown to reduce the ratio of softening for cherimoyas. In this paper, in order to minimize the damages due to post-harvest handling and transport, 0 or 1.6 mm of RVS was applied to cherimoya ‘Fino de Jete’ at 8 or 15 days before harvest (DBH). Post-harvest handling and transport was simulated and the fruits were stored at room temperature (RT) between 15 and 20 oC. After 15 days of storage, the fruits treated with 1.6 mm of RVS at 15 DBH showed less (p< 0.05) dehydration (7.4%); the kinetics of the fresh weight was not different when 0 or 1.6 mm of RVS were applied at 8 DBH. With a dose of 1.6 mm of RVS, there was a decrease (p< 0.05) in the loss of fruit firmness (7.5 and 5.7%) and in the loss of skin firmness (9 and 3%) for both dates of application with regard to the control.
