Leaf traits refer to the physical and chemical characteristics of a plant's leaves that influence its function and performance. These traits can include leaf size, shape, thickness, color, texture, and chemical composition such as nutrient levels or defense compounds. Researchers study leaf traits to understand how plants interact with their environment, respond to changes in climate, and compete with other species. Leaf traits can also be used to predict plant productivity, carbon sequestration, and ecosystem dynamics. Studying leaf traits can provide valuable insights into plant adaptation and evolution, as well as help in monitoring and managing ecosystems.
