Abstract

There are few embryological reports on wild legumes and even fewer on their seminal appendages. There are no existing studies on the complete ontogeny of these appendages in ONOBRYCHIS viciaefolia. In this work megasporogenesis, megagametogenesisand aril ontogeny were studied in ONOBRYCHIS viciaefolia.The OVULE ontogenesis and the megasporogenesis events in ONOBRYCHIS viciaefolia. were studied with light microscopy. The primordium is tetra-zonate and gives rise to an anatropous OVULE. The archesporium may consist of one or more archesporial cells, but only one of them undergoes meiosis, forming a linear shaped tetrad. Normally, only a single MEGASPORE is functional, which is located in the chalazal position, while the others degenerate very soon. Theyoung OVULE is hemianatropous but the mature one is anatropous, crassinucellar, and bitegmic; integuments form a zigzagmicropyle. A 7-celled embryo-sac is formed corresponding to thePolygonum type.
