Ruderal plants in the Plateau Conquistense, Bahia and its importance.

Abstract

This paper presented a checklist and characterized the importance of ruderal flora of Farm David Santos (FDS) in Vitória da Conquista - BA. In this area we collected, herborized and deposited in HUESVC the herbaceous and shrub plants, which were then categorized as to its type of importance. The results show that 124 species were found in 89 subtended genera in 27 families. The families with highest species richness were Asteraceae with 19 spp. and Fabaceae with 16 spp. The FDS area can be considered median rich in species. The vegetation type that contributed the greatest number of species was the disturbed forest (capoeira) with 65 species, Evidence points that possibly the species Acanthospermum australe, Bidens pilosa, Chamaecrista rotundifolia, Diodia teres, Emilia sonchifolia, Mollugo verticillata, Portulaca oleracea, Sida rhombifolia, S. spinosa, S. planicaulis are potentially weeds to the Conquistense Plateau region. As regards the importance of the species, most were considered positively importance, though not exclusively. It is suggested that for improving utilization of ruderal plants are needed, incentives for research on ecological interactions, infestation capacity and detection varieties with usable features, domestication strategies based on genetic improvement, exploring knowledge of ruderal plants uses and discloses them, and, finally, establish strategies to exploit the potential of ruderal species incorporating them into the agricultural system, rather than just fight them.
