Conteúdo: | GUAYULE used water for the first two years in response to soil water availability and environmental demands at Mesa, Arizona. Evapotranspirations for three cultivars from May 1981 through December 1982, averaged 3000, 2410, 1720, 1470, and 1520 mm (118, 95, 80, 68, 58, and 60 in.) in decreasing order of water applications for six irrigation treatments. Plant canopy temperatures as measured by an infrared thermometer showed a progressive increase in stress behavior as irrigation water applications decreased. Plant temperatures as high as 8 graus C (14 grausF) above air temperatures were record during the summer months on the dry treatment without plant death whereas, plant temperatures on thewet treatment were seldon more than 1 graus (1.8 graus F)above air temperature. Rubber yields were significantly higher on the wetter than drier treatments because of the greater biomass on the on the wetter treatments. Although guayule can withstand long periods of drought, optimum production will not be achieved in a short period without using an extremely wet irrigation schedule.
