Plântulas e sementes de macrófitas aquáticas de lagoas do Pantanal Sul-Mato-Grossense

Abstract

Seedlings and seeds of aquatic macrophytes from ponds of the Pantanal of Mato Grosso do Sul. Seeds and seedlings are important for re-colonization and stabilize flooded areas. Currently, no systematized data is available for seedlings, seeds, and other diaspores of aquatic macrophyte species from seasonally flooded areas of the Pantanal. We developed a guide describing the morphology and the propagation strategies of diaspores and seedlings, some of which are described for the first time. Plants, seedlings and seeds were collected in ponds from the Pantanal subregion called Abobral. Plates include morphological and taxonomic data of 24 species, distributed in 14 families: Alismataceae (3 spp.), Araceae (1), Polygonaceae (3), Pontederiaceae (3), Cyperaceae (1), Lentibulariaceae (2), Nymphaeaceae (3), Onagraceae (2), Cabombaceae (1), Cannaceae (1), Hydrocharitaceae (1), Marantaceae (1), Plantaginaceae (1) and Rubiaceae (1). This sampling contemplates all life forms of macrophytes. While some species presented mainly vegetative propagation, such as stolon, fragmentation and sprouting, others also developed fruits.
