Effect of submersion on the percentage germination (number of germinating seeds in relation to the total number of seeds) and MGT for seeds of eight tree species of Central Amazonian floodplains. Non-submerged seeds were placed on moistened double-layered filter paper. Submerged seeds were kept in 300 mL distilled water (water column of ∼3 cm). In both treatments, four replicates of 25 seeds each were used, except P. glomerata in which four replicates of 15 seeds each were used. Data expressed as mean ± standard error. Bold values indicate that non-submerged and submerged seeds differed significantly (P < 0.05) according to the REML test.
