Abstract

Studies conducted near Bernardo, New Mexico, from 1962 to 1964 involved the influence of environment on weekly shoot growth and carbohydrate storage in roots and stems of undisturbed saltcedar (Tamarix pentandra Pall.) and of regrowth (plants regrown from having been mowed the previous winter). Environmental variables were air and soil temperatures, relative humidity, wind, solar radiation, barometric pressure, evaporation from a free-water surface, depth to water table, and water quality. No variable or combination of variables could be used to predict accurately the maximum shoot growth period or the minimum carbohydrate storage. An analysis of the individual weekly growth patterns of plants showed considerable week-to-week variation in the rate of growth. Wide variations in total carbohydrate storage in roots and stems within weeks also were evident, and probably reflected the variation in growth.
