A cultura da cebola ocupa o segundo lugar entre as hortaliças quanto ao valor bruto da produção em Santa Catarina, constituindo-se em importante produto na economia estadual. Alem disto, a produção local tem poupado significativo volume de divisas ao pais ao mesmo tempo em que ocupa mão-de-obra no inverno gerando rendas para cerca de 17.000 pequenos produtores catarinenses. As atuais recomendações de fertilizantes para cebola em Santa Catarina tem caráter preliminar e foram derivadas, principalmente, de revisão bibliográfica (EMBRATER/EMBRAPA 1979). Uma vez que os fertilizantes constituem componente significativo no custo de produção da cebola, tornou-se necessário realizar pesquisa visando aperfeiçoar as recomendações em vigor, com enfase particular no aspecto econômico da adubação. |

Garcinia brasiliensis (Mart.) is a native Amazonian tree cultivated throughout Brazil. This plant can tolerate flooding or submergence for several days, during certain periods of the year. The morphophysiological changes of G. brasiliensis (Mart.) seedlings were assessed that may favor their survival in flooded environments. Seedlings with six fully expanded leaves were placed in tanks so that their roots were submerged for 90 days. Antioxidant enzymatic activity and the contents of H2O2, soluble sugar, starch, and amino acid of the roots were evaluated on six harvesting occasions. At the end of the experiment, the dry mass and root morphology of the seedlings were determined. Flooding lead to a decrease in dry mass of roots and aboveground parts, as well as root length (58%), surface area (51%) and volume (43%), especially of roots with smaller diameter. The roots of the flooded seedlings presented thicker exodermis and greater xylem number, thicker phloem and fewer xylem fibers. There was a small amount of aerenchyma in the roots and hypertrophied lenticels were detected at the base of the stem. Superoxide dismutase activity was significantly higher in flooded roots at all harvesting times, and ascorbate peroxidase and catalase activities were highest during the last two harvestings. H2O2 content increased after 40 and 55 days of flooding, followed by a drastic decrease. After 70 and 90 days of flooding there was an expressive increase in soluble sugars, and at 90 days, a reduction in starch content. No differences were observed in amino acid content.
