| Abstract: | Periodic flooding of trees in tropical floodplains and reservoirs where water levels fluctuate is a common phenomenon. The alternating terrestrial and aquatic periods with advancing and receding floods poses a variety of constraints to the plants growing in this habitat. If flooding is recurrent before the plants recover from previous flooding, injuries will accumulate and serious damage may occur. Therefore, when assessing plant resistance to flooding, it is important to consider the ability of plants to r... |
