Scarified (H2SO4 for five minutes) and intact (untreated) seeds of Panicum maximum were subjected to several osmoconditioning treatments in different experiments using PEG 6000 solution (288 g litre-1) at 15, 20 and 25 degrees C over 7-28 days. Osmoconditioning for more than 14 days reduced mean germination time (T50) and final germination percentage. The best results were obtained after a 7-day imbibition at 15 and 25 degrees C for scarified and intact seeds, respectively.
