Os resultados deste trabalho confirmam que a mobilização dos lipídios e das proteínas de reserva ocorre de forma coordenada durante o crescimento pós- germinativo inicial em girassol, corroborando a hipótese de que a aplicação externa de fontes de carbono (sacarose) e nitrogênio (L-glutamina) é capaz de atrasar a mobilização dessas reservas nutritivas de forma cruzada. Além disso, considerando as mudanças nos padrões de mobilização das reservas e a partição dos seus produtos, proporcionadas pela aplicação externa de diferentes reguladores do crescimento, é evidente que os efeitos dos metabólitos e dos hormônios devem envolver, pelo menos em parte, mecanismos de ação distintos.
