Topic 9 - Leaf energy budgets
Essential elements from Topic 9:
Here, we expand on the essential microclimate concepts necessary for you to understand how leaves interact with their surrounding physical environments in ways that influence leaf temperature, metabolisms, and growth.
1. Leaves interact with their physical environment through mass and energy exchange. One consequence of this interaction is the determination of leaf temperature, with cascading effects on growth, metabolism, respiration, and transpiration.
2. In this topic we explore the leaf energy budget and the mechanisms that plants have in place to couple leaves to their physical environment.
3. We then discuss the leaf adaptations that plants have to influence their leaf energy budgets, modulating leaf temperatures and transpiration and also avoiding lethal leaf temperatures.
