Leaf absorptances of Mohave and Sonoran desert plants
Oecologia, 1981Leaf absorptances to solar radiation in the 400-700 nm (photosynthetically useful wavelengths) are presented for a diversity of species in the Mohave and Sonoran Deserts of North America. As a life form shrubs are shown to have the widest range of absorptance, with perennial herbs and cacti exhibiting a smaller range, and very little variation in leaf ...
