Resumen
The present work reports on certain structural aspects of seeds of Kochia scoparia (L.) Schrader. Different stages of embryonic development are studies with the finding that mainly on the ontogeny of the vascular system. A study is made of the transition area. According to analysis of the development of the seeds it is possible to infer the initial existence of three separate vascular systems in the seedling, that later contact. A study is made of the developmental mode of the secondary vascular system of the stem and the sequential activity of the several meristems. The asynchrony appears as an important functional characteristic.
