Leaf 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 absorptances among trees and annuals. The measurement of leaf absorptance at 625 nm is shown to be the same as the leaf absorptance to solar radiation over the 400-700 nm. Over a wide range of species and absorptances, the total solar leaf absorptance (400-3,000 nm) is shown to be closely related to the 400-700 nm leaf absorptance.
本文给出了北美莫哈韦沙漠和索诺兰沙漠多种植物叶片在400 - 700纳米（光合有效波长）范围内对太阳辐射的吸收率。作为一种生活型，灌木的吸收率范围最广，多年生草本植物和仙人掌的吸收率范围较小，树木和一年生植物的叶片吸收率变化很小。结果表明，在625纳米处测量的叶片吸收率与400 - 700纳米范围内叶片对太阳辐射的吸收率相同。在广泛的物种和吸收率范围内，叶片对太阳辐射的总吸收率（400 - 3000纳米）与400 - 700纳米的叶片吸收率密切相关。
