| description | <i>Prunus</i> species are important crops in temperate regions. In these regions, drought periods are predicted to occur more frequently due to climate change. In this sense, to reduce the impact of climate warming, obtaining new tolerant/resistant cultivars and rootstocks is a mandatory goal in <i>Prunus</i> breeding. Therefore, the current study assembled three <i>Prunus</i> species including almond, (<i>P. dulcis</i> Mill D.A. Webb), apricot (<i>P. armeniaca</i> L.) and peach (<i>P. persica</i> L.) to model the temporal effects of drought. A hybrid peach × almond and a wild almond-relative species <i>Prunus webbii</i> were also included in the study. Physiological traits associated with photosynthetic activity, leaf water status, and chlorophyll content were assessed under three watering treatments. Results showed that effects of time, genotype, and treatment interact significantly in all traits. In addition, results confirmed that <i>P. webbii</i> have a greater tolerance to drought than commercial rootstocks. However, “Real Fino” apricot showed the fastest recovery after re-irrigation while being one of the most affected cultivars. In addition, from the better response to these watering treatments by the almond genotypes, two different trends were observed after re-irrigation treatment that clearly differentiate the response of the almond cultivar “Garrigue” from the rest of <i>Prunus</i> genotypes. A better characterization of the short-term drought response in <i>Prunus</i>, an accurate and more efficient evaluation of the genotype effect was obtained from the use of mixed models considering appropriate variance–covariance structures. Although the advantages of these approaches are rarely used in <i>Prunus</i> breeding, these methodologies should be undertaken in the future by breeders to increase efficiency in developing new breeding materials. |
