Descripción

A phytosociological analysis was carried out in Ourinhos, São Paulo State, Brazil, in order to evaluate the weed community behavior prevalent in P. notatum Flügge turfgrass, recently installed through sowing. Four evaluations were accomplished, between March and May (2007), after turfgrass and weeds emergence. Through the analysis, 23 weed species were identified, distributed in nine families, pointing out the number of species per family for Poaceae and Malvaceae. The Sida glaziovii (Malvaceae), Cyperus flavus (Cyperaceae), Cyperus rotundus (Cyperaceae), Chamaecrista rotundifolia (Leguminosae), and Cynodon dactylon (Poaceae) species showed the highest relative frequencies; S. glaziovii, Chamaesyce hyrta (Euphorbiaceae), C. flavus, Crotalaria lanceolata (Leguminosae), Sida cordifolia (Malvaceae), and Sida spinosa (Malvaceae) the highest abundance level; and S. glaziovii > C. flavus > C. rotundus > C. rotundifolia > C. dactylon the highest importance value index (IVI).
