Phenological Stages of the Species Jacaranda mimosifolia D. Don. According to the Extended BBCH Scale
Ignacio Gandía-Ventura, Isabel López-Cortés, Borja Velàzquez-Martí

TL;DR
This study describes the seasonal growth stages of the jacaranda tree in Mediterranean climates using a standardized scale and calculates the heat needed for its annual cycle.
Contribution
The study provides the first detailed phenological description of Jacaranda mimosifolia using the BBCH scale and quantifies its thermal requirements.
Findings
Jacaranda completes its annual cycle after accumulating about 3800 growing degree-days (GDD).
Thirty-nine secondary stages were identified across seven principal growth stages using the BBCH scale.
The phenological framework aids in improving management practices for jacaranda in Mediterranean climates.
Abstract
Jacaranda mimosifolia D. Don. is a popular ornamental tree widely planted in Mediterranean cities for its attractive foliage and purple flowers. However, its seasonal development has never been formally described under these environmental conditions. In this study, we monitored jacaranda trees throughout the year and identified their main growth phases using the standardized BBCH phenological scale. We also calculated the amount of heat required for the species to progress from winter dormancy to leaf fall, known as growing degree-days (GDD). Our results show that jacaranda completes its annual cycle after accumulating about 3800 GDD, indicating that it grows successfully in Mediterranean climates. This information can help improve management practices in ornamental plantings and support decisions regarding the potential use of jacaranda in experimental or agroforestry cultivation…
