This study aimed to follow up the in orchard physiological ripening evolution of Luizet apricots using visible and near infrared spectroscopy. The potential of development of a decision support tool for the harvest of Luizet dedicated to distillation was assessed with non-destructive measurements on fruits harvested every day. Physicochemical parameters evolved as expected on the trees, showing increasing soluble solids content and ground color and decreasing firmness and acidity. The visible spectroscopy (DA-meter) allowed to predict harvest date with a precision of one day and near infrared spectroscopy (Phazir) with a precision of three days. Both portable devices allowed good monitoring of fruit ripening on the trees and can be considered as reliable decision support tools for optimal harvest time of Luizet dedicated to distillation.
