Abstract Pavonia cymbalaria A. St.-Hil. & Naudin (Malvaceae) is a native species of the southern mountains in the Province of Buenos Aires. Its morphological characteristics become it as a potential candidate for ornamental use. Crop requirements and seed germination were evaluated for this species in this study. Different treatments were applied to 640 mericarps: removal of carpel residues, mechanical scarification or exposition of mericarps and nude seeds to cold conditions. An untreated control was used for each of these treatments. Germination only occurred on nude seeds; this implies the existence of an extrinsic dormancy imposed by the… More >
