Morphology and ultrastructure of maternal seed tissues of soybean in relation to the import of photosynthate [Route of photosynthate transport]

Cytological observations were made on developing seeds of soybean (Glycine max (L.) Merr. "Amosy 71") using scanning and transmission electron microscopy and light microscopy. Attention was focused on the maternal tissues of the seed coat and embryo sac. An hypothesis of photosynthate impo...

Description
Summary:Cytological observations were made on developing seeds of soybean (Glycine max (L.) Merr. "Amosy 71") using scanning and transmission electron microscopy and light microscopy. Attention was focused on the maternal tissues of the seed coat and embryo sac. An hypothesis of photosynthate import, unloading, and movement to the embryo is presented based on the results of these studies.
