Table 5.
Shoot length, number of leaves and biomass distribution in Amazonian and Cerrado plants of Genipa americana and Guazuma ulmifolia that were kept in well-watered conditions after being subjected to 30 days of flooding (waterlogging or complete submersion). Each cell is the mean ± standard error of five harvested plants taken 30 days after the start of the well-watered conditions. Different uppercase letters within the same column indicate significant differences between Amazonian and Cerrado plants, while different lowercase letters within the same row indicate significant differences across the three hydric conditions.
