RESUMO:

In Brazil, located in the Midwest region, the Pantanal, being the largest floodplain in the world, annually faces considerable degradation due to human activities, mainly due to fires and deforestation. Faced with this reality, ecological restoration emerges as an essential measure to recover these ecosystems in balance. A promising approach to assist in the mitigation of these areas is with the use of local native species, therefore, a species that is widely found and well adapted to these areas, from the Fabaceae family is the Inga vera Willd., known as Ingá-Banana, due to its abundance and adaptation to these places with seasonal flooding and play a significant role in reforestation and the recovery of degraded riparian forests. Considering the importance of restoring flooded wetlands and through harm reduction approaches, the objective of this study was to evaluate which sowing method favors the highest emergence rate, in addition to investigating the effect of the hydrological cycle on germination, emergence and survival of I. vera seedlings. The experiment was carried out in the Pantanal, in Cáceres – MT, covering different environments carried out throughout the years 2022 and 2023. The quantitative evaluations carried out included germination experiments with weekly observations over 13 to 18 weeks, as well as a flooding experiment in plots created with different levels to simulate the water cycle of the Pantanal, monitored for 07 months. The data collected allowed for static analyses, including the calculation of the average time of emergence, percentage of emergence, time of submersion and percentage of survival. We obtained satisfactory results, with no occurrence of 0% seed emergence. Direct sowing in moist soil, without long periods of submersion, proved to be more efficient, while the direct sowing method in a pit, this one with or without litter, stood out as the most effective for restoration, ensuring the safe development and growth of seedlings. In addition, areas with levels below 3.0 m in relation to the river level were identified as unsuitable for transplanting seedlings of this species, as it cannot withstand long periods of flooding.
