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, ...

Abstract:
... Selection of crops with a high water use efficiency (a low transpiration ratio, TR) is one approach to water conservation in semi-arid regions. The TR is the ratio of the amount of transpiration to dry weight gain. In a greenhouse experiment, unstressed agave (Agave americana L.) and corn (Zea mays L.) had TRs of 114 and 133, respectively. Under stress, the TR of corn increased to 166, but remaine ...

Abstract:
... Analysis of saponins by thin layer chromatography (TLC) is reported. The solvent system was n-butanol:water:acetic acid (84:14:7). Detection of saponins on the TLC plates after development and air-drying was done by immersion in a suspension of sheep erythrocytes, followed by washing off the excess blood on the plate surface. Saponins appeared as white spots against a pink background. The protocol ...
