ABSTRACT
Aiming at evaluating genotype influence on the concentration of protein and oil, immature seeds of cultivars CD 202 and CD 206 were removed from the mother-plant, in the stage R5, and were grown in vitro, in a liquid culture medium which contained 20, 40 and 60 mM of glutamine, during eight days. Afterwards, the concentrations of oil and protein were compared to the contents of the seeds cultivated in vivo. With a higher availability of glutamine for the seed, there was an increase of protein content. The genotypes were statistically different as far as the protein concentration was concerned,which confirmed that the genotype had influence on the concentration of protein in the seed. Oil and protein concentrations were inversely related when a variation of glutamine concentration occurred.
RESUMO
Com o objetivo de avaliar a influência do genótipo sobre as concentrações de proteína e óleo, sementes imaturas das cultivares de soja CD 202 e CD 206 foram retiradas da planta mãe no estádio R5, cultivadas in vitro em meio de cultura líquido por oito dias, contendo 20, 40 e 60 mM de glutamina. Depois disso, as concentrações de óleo e proteína foram comparadas com as das sementes que continuaram seu desenvolvimento in vivo. Com a maior disponibilidade de glutamina para a semente, houve um aumento do conteúdo protéico nas sementes. Quanto às concentrações de proteína, os genótipos foram estatisticamente diferentes, levando a afirmar a sua influência na concentração de proteína na semente. As concentrações de proteína e óleo foram inversamente relacionadas quando variou a concentração de glutamina.
