Abstract:
... 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, ...
