- ... Partial destruction of ozone in the earth's upper atmosphere (stratosphere) will increase levels of ultraviolet (UV) radiation that reach the earth's surface; consequently, plants could be exposed to harmful amounts of UV-B radiation (280 to 320 nm). The objective of our research was to characterize the reflectance, transmittance, and absorptance of UV-B radiation by leaf epidermises. Accordingly, ...

- ... Cotton plants (Gossypium hirsutum L.) were grown in the growth chamber, greenhouse, and field to study effects of leaf matttration on spectral properties, water content, and thickness of single leaves. In the 500- to 750-nm region and at 1,650 and 2,200 nm, leaf age had a variable effect on reflectance. Over the 750- to 1,350-nm wavelength interval (WLI), leaf reflectance was a maximum at node 8, ...
