Increased Temperatures Promote Fruit Enlargement Through Cellular and Transcriptomic Changes in Raspberries (Rubus idaeus L.) cv. Heritage

Jesús Hernández-Urrieta, Sebastián García, Lamia Estait, Francisca Aguilar et autres

Climate change is expected to increase temperatures in agricultural producing regions, potentially affecting fruit development and quality. To date, the molecular responses of raspberry fruits to moderate warming under field conditions have not been explored. In this paper, raspberry plants (Rubus idaeus …

Physiological, Productive, and Soil Rhizospheric Microbiota Responses of ‘Santina’ Cherry Trees to Regulated Deficit Irrigation Applied After Harvest

Tamara Alvear, Macarena Gerding, Richard M. Bastías, Carolina Contreras et autres

Chile, the leading exporter of cherries (Prunus avium L.) in the southern hemisphere, faces sustained variations in precipitation patterns and high evaporative demand in its productive areas. The low availability of water during the period of highest environmental demand makes it essential …

Late Water Deficits Improve Intrinsic Water Use Efficiency, Fruit Maturity, and Acceptability in Yellow-Fleshed Kiwifruit cv. Soreli

Arturo Calderón-Orellana, Mauricio Calderón-Orellana, Catalina Atenas, Carolina Contreras et autres

Water scarcity poses a significant threat to kiwifruit production, especially in Mediterranean climates. This study investigated the impact of late-season regulated deficit irrigation (RDI) on water use efficiency and fruit quality of yellow-fleshed kiwifruit (Actinidia chinensis cv. Soreli) over two seasons in …

Calcium Allocation to the Tree Canopy and the Edible Part of Sweet Cherry Fruit Is Hindered by Boron Soil Deficiency

Claudia Bonomelli, Gerardo Arredondo, Adriana Nario, Pamela Artacho et autres

Calcium (Ca) and Boron (B) are structural components of the cell wall with limited phloem mobility. The absorption, movement, and distribution of these two nutrients have a greater effect on leaves than on fruits since their transport is dependent on transpiration flow. …

Influence of preharvest environmental conditions and postharvest relative humidity on the appearance of orange peel disorder in sweet cherry during fruit development and storage

Francisca Coye, Arturo Calderón-Orellana, Juan Pablo Zóffoli, Carolina Contreras

Orange peel, a physiological disorder, has been reported in Chilean sweet cherries (Prunus avium (L.) L.) after 35-45 d under modified atmosphere packaging (MAP).The ontogeny of the disorder is unknown, and preharvest factors have not been thoroughly investigated.This study involved two experiments …

Aroma Compounds Are Responsible for an Herbaceous Off-Flavor in the Sweet Cherry (Prunus avium L.) cv. Regina during Fruit Development

Juan David Villavicencio Romero, Juan Pablo Zóffoli, Anne Plotto, Carolina Contreras

An herbaceous/grassy-like flavor has been reported by Chilean producers of Regina sweet cherry. There are no previous academic reports related to this flavor occurrence. Sweet cherries from five phenological stages were collected from six orchards with high herbaceous flavor incidence spanning Chilean …
