The aim of this study was to evaluate the growth and carbohydrate\udpartitioning in seedlings of Sebastiania membranifolia in response to flooding. Seeds\udwere germinated in BOD type chamber at 25 ºC, on moistened germitest paper. The\udseedlings were acclimatized for 20 days in a growth chamber and then transplanted into\udpolypropylene bags containing substrate consisting of sand , manure and soil (1:1:1), and\udtransferred to a greenhouse protected with 50% shading for 40 days. At the end of this\udperiod three treatments were established: control (well watered), root flooded and\udcompletely flooded. The flooding was accomplished by placing the bags containing the\udplants individually in buckets with greater capacity. The evaluations were conducted at\udintervals of 12 days for a total period of 36 days, with four replicates for each treatment\udand evaluation period. The number of leaves, branches, stem height and dry weight of\udthese parts, increased linearly in control plants over the period analyzed. For the flooded\udroots treatment, these parameters increased only until the 24th day, and in completely\udflooded plants, in general, this stress did not allow the growth of plants. The content of\udtotal soluble sugars, reducing sugars and starch were significantly lower in completely\udflooded plants, both in the leaves and in the roots. Root flooded plants had significant starch\udreduction in the roots, with values of the last measurement equal to those observed in\udcompletely flooded plants. These results suggest that S. membranifolia may be a promising\udspecies for revegetation of depleted areas subject to intermittent flooding
