Micromorphology and anatomy of fruit in Iris pseudacorus L.

Based on the suggestion that flower and fruit are integrally evolving structures, we aimed to reveal floral traits persisting in structure Iris pseudacorus, a widely distributed riparian species Ukraine. We intended compare results with other studied previously constancy of micromorphological features interior structure. revealed exomorphological peculiarities fruiting ovary using model vertical zonality gynoecium, vascular anatomy, general anatomy wall. In I. presence three zones: short synascidiate zone, long symplicate zone bearing uniseriate seeds, hemisymplicate located beak. The system is composed dorsal, septal, ventral veins. Each dorsal veins divides radially into outer tepal trace, stamen carpellary bundle, while each septal vein tangentially bundles inner trace. Paired enter from its bottom supply ovules seeds. exocarp polygonal cells thickened cellulose walls. endocarp uniseriate, unlignified, live prosenchymal cells, which elongated tangentially. parenchymatous mesocarp, great number secretory canals tannin-like content occur. dehiscence valves proceeded by both slits. Dorsal slits formed along grooves provided small-celled tissue surrounding sutures carpels provides fruit. Hence, pseudacorus comparable species. Our investigation confirmed zonality, placentation, gynoecium can be appropriately estimated stage because structural components ovary, developed at pre-anthetic phase, persist
