Megasporogenesis and megagametophyte development in ten species of Oxalis

Mostrar todas las versiones(2)

Ovule morphology, megasporogenesis and megagametogenesis of ten species of Oxalis were examined. The ovule is anatropous, bitegmic and the integuments form a zig-zag micropyle. The type of female gametophyte development is variable in the studied species. The majority of them have a monosporic Polyg...
