phenology
Phenology is the study of recurring biological events in plant life cycles—such as flowering, fruiting, and germination—and how these events are timed in response to seasonal and climatic conditions. This research is essential to plant science because phenological patterns directly influence reproduction, ecosystem interactions, and the critical timing between plants and their pollinators and seed dispersers. Understanding phenology is vital for predicting how plants will respond to environmental changes and climate variability.
