摘要

The allocation of resources in Schizolobium parahyba was analyzed measuring the total soluble sugars, starch levels and biomass. After breaking dormancy, 200 seeds were sown in substrate composed of rice rind and sand (1:1). Ten seedlings were collected to measure the soluble sugar and starch level and ten were used to measure the fresh biomass (MF) and dry biomass (MS) on the 7, 14, 21, 28, 35 and 42 days after germination (DAG). The seeds showed a 94.5% germination rate. The total soluble sugar levels were greater in roots, stems and epicotyls. The cotyledons had the greatest starch level because they are the store organs of this plant. The increase of MF is directly proportional to the increment of total soluble sugars and. The relation between biomass, total soluble sugar and starch have shown the mobilization of the store from cotyledons to the other structures of the plant while the reduction of biomass and sugars of cotyledons result in an increase of biomass in epicotyls, stems and roots of the seedling.
