Road dust induced increase of leaf temperature


Eller, Benno M, Road dust induced increase of leaf temperature: .


Only a minor part of the absorbed global radiation by plant leaves is used in photosynthesis. The rest is converted into sensible heat influencing energy balance and temperature of leaves. Dust cover on leaves increases their absorptivity and an increase of leaf temperature influencing productivity of the plants is to be expected. Spectral properties and temperatures of leaves covered with road dust and identical but clean leaves were measured. Absorptivity of dusty leaves is more than doubled for the waverange 700 to 1350 nm. Temperatures of dusty leaves are 2 to 4�C higher than those of clean leaves. Absorbed incident global radiation was calculated in order to discover which waverange of incident radiation caused the temperature [...]
