Phytotoxic Activity of <i>Myrciaria cuspidata</i> O. Berg, a Dominant Myrtaceae Woodland Tree Native of Brazil.

ABSTRACT: Limited phytodiversity and regeneration rates occur in some of the southern Brazilian formations known as the Myrtacean Woodlands. Data on phytotoxicity, chemical composition, and allelopathic potential of Myrciaria cuspidata O. Berg, a dominant species in such woodlands, is missing. In this study, both the chemical composition and phytotoxic activity of an aqueous extract (AE) from M. cuspidata leaves were investigated. Target plants were the model species Lactuca sativa L. and the weed Bidens pilosa L. Germination rates, seedling growth, and phenotypic responses of target species were assessed following AE application to determine the inhibitory capacity of M. cuspidata leaf extract. Germination of L. sativa was reduced and delayed in the presenc
