|metadata.revistascielo.dc.description:||This work aimed to verify the effects of biostimulant doses, applied through seeds, on faveiro (Dimorphandra mollis Benth.) seeds and seedlings vigor. Seeds were previously sulfuric acid scarified in two consecutive years experiments. On 2006 August (first experiment) seeds were submitted on Stimulate®: 0; 3.5; 7.0; 10.5 and 14 mL.0.5 Kg-1 doses (first experiment); and seeds picked in August, 2007, were Stimulate:0; 15; 20 and 25 mL.0.5Kg-1 of seeds treated (second experiment). After the biostimulant treatment seeds were sowed in cells trays containing 1:1 (v:v) distroferric red latosol + plantmax®. The effect of different Stimulate® doses on Dimorphandra mollis seeds collected in different years were evaluated on the emergency percentage, speed emergency index, root length, aerial part height and dry seedling weight. It was conducted on entirely casualized with four repetitions of 25 seeds each treatment. The 14 mL (2006 lot) and 15 mL (2007 lot) 0.5Kg-1 of seeds doses provided larger percentage (50% and 66%, respectively) and speed emergency indexes (0.67 and 0.9 respectively). The 20 mL.0.5Kg-1 of seeds dose treatment favored the aerial part length, but it didn't influenced the other Dimorphandra mollis seedlings vigor indexes.|
