A temporal shift in resource allocation facilitates flowering before leaf out and spring vessel maturation in precocious species.
Jessica A SavagePublished in: American journal of botany (2019)
A shift in the timing of resource allocation in precocious flowering plants allowed them to flower before the production of mature vessels and minimized the significance of seasonal changes in vascular function to their flowering phenology. The low investment required to complete floral development in the spring when the plant vascular system is often compromised could explain why flowers can emerge before leaf out.
