Abstract
This work deepens the physiological knowledge of “Prunus salicina” Lindl. cv Angeleno, a fruit tree with great economic importance in Extremadura, susceptible to improvements in the management of irrigation strategies and of which, at present, there is little bibliography about its water behavior and its response to periods of deficit. A first study of the water behavior of this cultivar served to establish the hydric indicators with best fit to it. Throughout eight years of study three irrigation strategies have been established in a plantation of “Prunus salicina” Lindl. Angeleno: a control strategy replacing the crop water needs, a controlled deficit irrigation strategy that has been validated in other stone fruit tres and a third strategy adapted to the ecophysiological behavior of the cultivar thanks to a previous study on the same plantation. In all treatments, the response of the tree to periods of stress and the repercussions on production, final size and quality of the fruit were studied. The work carried out in this document represents an advance in the knowledge of the physiological behavior of the Japanese plum tree cv 'Angleno and the development of the fruit, making it possible to manage more efficiently the irrigation strategies designed for this cultivar, offering better use of water without reducing production (kg ha‾¹) or the final size of the fruit.
