Plant Water Relations and Carbon Dynamics

When light strikes a leaf, part of the light spectrum is reflected towards the observer. Plant reflectance is governed by leaf surface properties and internal structure, as well as by the concentration and distribution of biochemical components, and thus remote analysis of reflected light can be used to assess both the biomass and the physiological status of a plant. Such assessment is of great value for applications such as determining the extent to which vegetation is stressed or at risk from fire.
