Abstract

Abstract

The seed coat of mature soybean [Glycine max (L.) Merr.I has natural openings the micropyle and pits (pores). To determine when pits appeared during development of the seed coal scanning electron microscopic studies were made at weekly intervals after pollination. Pits appeared in the two accessions studied at about growth stage R7 (beginning maturity), 7 to 14 days before R8 (full maturity). micropyle developed before pollination and usually was an open structure. However, in ‘Union’, a micropylar plug was observed at 3 weeks after pollination. The micropyle was a well defined natural opening in the seedcoat from before pollination to maturity, whereas seed coat pits only began to form as the seed began to desiccate.
