AB The root distribution of Peltophorum was investigated after two years of pruning (twice a year) at three different heights (25, 50 and 75cm). Pruning height had a marked effect on the number of branch roots originating from the stem base. Possibilities are discussed for manipulating the tree so as to form a root distribution pattern desirable foe alley cropping.
