RESUMO

Foram analisados os constituintes principais de sementes dos cultivares Santa-Rosa, IAC-3 e UFV-1 de soja, armazenadas por doze meses em condições ambientes.
Ao final do armazenamento, os teores de extrato etéreo e de açúcares solúveis totais aumentaram, ao contrário do teor de polissacarídeos, viabilidade e vigor das sementes, que diminuíram.


SUMMARY

Chemical analyses were made on seeds of cultivars Santa-Rosa, IAC-1 and UFV-1 which were stored for 12 months under normal storage conditions. The percentage of ether extract and total sugar increased with time of storage, whereas, the percentage of polysaccharides, seed germination and vigor decreased.
