Phenological Stages of the Species Jacaranda mimosifolia D. Don. According to the Extended Bbch Scale

The jacaranda (Jacaranda mimosifolia D. Don.) is a species with a prominent role in urban gardening and to which new uses are increasingly being found, such as timber production or the production of antioxidant compounds for the medical industry. In this article we study the environmental conditions of the western Mediterranean, such as temperature, in order to make a phenological description of the species due to the growing interest in its cultivation and to find out how these conditions affect its development. Its phenology has been classified based on the extended BBCH, establishing ten stages and assigning them a digit. These describe bud dormancy, bud burst and leaf growth, inflorescence emergence, flowering, fruit set, fruit ripening and leaf senescence. Within each of the seven stages, sub-stages are defined with a second digit. All the phenological stages observed have been described, assigning photographs to those most representative of the annual cycle of the species. In order to know how each phenological stage has developed according to temperature, the thermal integral has been calculated from the thermal data obtained. Knowledge of the phenology of the species allows us to know its adaptation and the viability of its cultivation in the latitudes studied, as well as its possible response to other geoclimatic environments.
