Abstract

Vegetative rescue needs to be better studied, especially in tropical native species, especially on species of commercial interest such as Anadenanthera peregrina . We aimed to know the influence of the season and tree size on trunk girdling in a pure and uneven age population of A. peregrina. The population was divided into six diametrical categories varying from 5 to 30 cm in diameter at breast height (DBH), and the girdling happened in two seasons, autumn and spring. The design was in randomized blocks with six replicates with a plant per plot. The girdling was efficient for the vegetative rescue of A. peregrina. The size of the trees influenced the number of trees that sprout and the average number of shoots per tree. The season influence how fast the shoots appear, the number of trees that sprouted, and the number of shoots per tree. The girdling of the trunk on A. peregrina trees shows a higher potential for vegetative propagation when carried out in May (autumn) in trees with up to 25 cm of DBH.
