Plant phenology is the study of the timing of key lifecycle events in plants, such as flowering, leaf emergence, and fruit ripening. This field of research focuses on how these events are influenced by environmental factors such as temperature, precipitation, and day length. Understanding plant phenology is important for predicting the impacts of climate change on plant populations and ecosystems, as well as for informing agricultural practices and natural resource management. Researchers in plant phenology often use observational data, experimental manipulations, and modeling approaches to study the timing of plant life cycle events.
