Abstract

A phenological study of Acacia berlandieri, A. minuata, A. rigidula, A. schaffneri, and Chloroleucon ebano was conducted at three sites in the lower Rio Grande Valley of Texas from July 1998 to August 1999. Flowering in Acacia species occurred between January and April 1999, and was influenced by precipitation only in A. minuata . The timing of flowering appears to be influenced by the amount of time needed for fruit maturation. Precipitation, photoperiod, and temperature influenced the timing of fruiting in all species except A. berlandieri . Shoot elongation and leaf maturation in Acacia species were positively correlated with temperature and photoperiod.
