Abstract
http://dx.doi.org/10.5902/198050987565
Rapid and uniform germination of seeds followed by prompt emergence are highly desirable characteristics for the production of seedlings. The aim of this study was to identify sowing positions and types of substrate most likely to the seed germination process and growth of seedlings of Schizolobium parahyba (Vell.) Blake. To germinate the seeds, they were placed in the following positions in relation to the bottom of the furrow in the substrate: hilum uppermost, hilum at the bottom, supported on one side, seed on edge with its sides parallel to the walls of the bag. Three substrates were used: commercial plantmax substrate (control), pine sawdust and sand. The substrates were fully randomized in a 4 x 3 factorial design (four seed positions and three substrates), with four replications of 20 seeds. The parameters evaluated were: the percentage of emergence, the after emergence seedling deaths, the first-count test, the emergence speed index, and the seedling aerial part length. It was concluded that all the seed positions in pine sawdust sowing offer the more favorable conditions for the germination process and seedling growth of Schizolobium parahyba.
