“…In addition, there are modeling reports on the redistribution of soil water in P. salicina crops through the HYDRUS-2D model, which provides information on the amount of water required according to seasonality, cultivar, and soil water balance (Jovanovic et al, 2023). A 50% deficit irrigation regime based on the daily water requirements of the crop (ETc) in different varieties of P. salicina (including 'Santa Rosa') caused a decrease in the yield and fresh weight of the fruit, leaf area, stomatal density, chlorophyll concentration, and stomatal conductance (Hamdani et al, 2022;Hamdani, Hssaini, Bouda, Charafi et al, 2023).…”

The Japanese plum tree is of great importance in the productive development of Colombian fruit growers due to its nutritional contribution to human health, its great adaptability in the tropical highlands, and its good yields. This review presents the current investigative state of physiology of this plant and its management in tropical highlands, including aspects such as its ecophysiology, forced production, gas exchange, flowering, pollination, and fruit development. In Colombia, Japanese plum production systems are adapted between 1,670 and 2,900 m a.s.l., average solar brightness of 1,400 h per year, 12 h photoperiods, temperatures between 14 and 20°C during the day and 6 and 8°C during the night, and rainfall between 700 and 1,600 mm per year. Under these conditions, management can be implemented to produce cyclical crops of the Japanese plum. This management consists of the selection of varieties with low chilling requirement, chemical defoliation, proper fertilization, fruit and green pruning, and the application of chemical substances that promote the breaking of flower buds. Flowering and pollination require a high specificity so that they do not present incompatibility. The growth and development of the fruit requires 1,538 degree days until harvest. This review indicates the great adaptability, management, and production of Japanese plum in the Colombian high tropics.

“…Adaptation strategies are being developed and implemented (Hill et al, 1998). In Morocco, among the manifestations of these disturbances is the increase in the mean temperature largely highlighted at its effect on the spatial distribution of plant species (Wahid et al, 2007;Hamdani et al, 2023). Rosaceae are among the arboricultural species that are very affected by these temperature increases, especially in winter.…”

The date of endodormancy release and chill requirements of twenty-eight plum cultivars (Prunus domestica L. and Prunus salicina Lindl) growing in a collection at the experimental station of the National Institute of Agricultural Research of Meknes (Morocco) were determined according to three models namely the Chilling Hours model (in Chilling Hours, CH), the Utah model (in Chill Units, CU) and the Dynamic model (in Chill Portions, CP). In this regard, the forcing tests were conducted out on floral buds of all plum cultivars in order to follow the weight of buds in field and under controlled climate conditions. The heat requirements calculation was based on counting the Growing Hours Degree between the endodormancy release date determined by forcing tests and the flowering dates observed in field for each cultivar. Significant differences were revealed in chill and heat requirements between the plum cultivars studied, ranging from 336 to 522 CH, 645 to 1,046 CU, 37.5 to 55.93 CP and 6,618 to 9,673 GDH according to Chilling Hours, Utah, Dynamic and GDH models, respectively. In addition, the results showed great variability between cultivars according to their dormancy levels, ranging from low chill and heat cultivars (INRA-PR38, INRA-PR40 and Santa Rosa) to highest ones (Stanley, Prune d’Ente, Monglobe and Fortune), which generated differences in the dates of endodormancy release and flowering process. Correlations between chill requirements, heat requirements and flowering dates have been established since cultivars with low chill requirements (also low heat requirements) have earlier endodormancy release and flowering dates in comparison to those showed high chill requirements. The results obtained in this investigation constitute a basis to improve knowledge of the plum species cultivated under Moroccan climate conditions and make it possible to determine the most appropriate cultivation areas for these cultivars, given the current and future climate change.

Knowledge about the genetic potential of wild Prunus species is important for recognizing gene pools in germplasm and developing effective strategies for germplasm conservation and breeding. In this study, cultivated sweet cherry (Prunus avium L.) and relative wild Cereus subgenus genotypes belonging to P. microcarpa Boiss and P. incana (Pall.) Batsch. species were assayed in controlled drought conditions performing an integrated morphological, physiological, genomic and transcriptomic analysis of the stress response. These analyses were performed under well-watered and water-deficient conditions analysing morphology of leaves, gas exchange parameters and chlorophyll content differently affected by drought, especially under long-term water deficiency. From a genomic point of view, these genotypes were characterized using simple sequence repeat (SSR) markers. Finally, in the analysis of the transcriptional responses, drought tolerance candidate genes were analysed by quantitative PCR (qPCR). From a morphological point of view, P. microcarpa showed less leaf area, height and diameter in comparison to P. incana and mainly P. avium. The highest rate of photosynthesis in genotypes differently was observed in the control treatment and the lowest rate viewed during stress. The analysed genes showed different responses to drought in the genotypes, and more detailed analysis techniques to explain the molecular mechanisms of drought tolerance are needed in these genotypes. Our results provide a significant contribution to the understanding of how P. incana and P. microcarpa respond to drought stress, which may help to explain molecular and physiological mechanisms associated with the response to the drought of cherries. Additionally, these results show that wild cherries can be considered as a genetic source of drought resistance in breeding programs.
