Última Anatomy of the developing fruit of Metrodorea nigra A. St.-Hil. (Rutaceae) BABT Souza,Luiz Antonio de; Rosa,Sônia Maciel da; Moscheta,Ismar Sebastião. The pericarp and seed in development of Metrodorea nigra were investigated structurally.The flowers and fruits in different stages of maturation were fixed in FAA 50 and cross-and longitudinally sectioned, according to usual techniques. The differentiated epicarp was represented by the periderm of subepidermal origin. The mesocarp was parenchymatous. The endocarp was sclerenchymatous and originated from the meristematic action of the inner epidermis of the ovary. The seed was endotestal and originated from an anatropous, bitegmic and crassinucellate ovule. The nucellus and the endosperm occurred in small quantity in the mature seed. The embryo was straight with thick cotyledons. The seed and the endocarp were ejected in the autochory process. The fruit was...

(Rutaceae) BABT Souza,Luiz A. de; Moscheta,Ismar S.; Mourão,Káthia S. M.; Rosa,Sonia M. da. Studies on the morphology and anatomy of the flower and anthesis of Metrodorea nigra St. Hill. (Rutaceae) showed perfect flowers, which occurred in panicle. The peak of the flowering was August and September. The anthesis was diurnal and the species presented protandrous flowers. The green sepals and the red petals presented papillose epidermis with stomata and parenchymatic mesophyll. The tetrasporangiate anther presented a papillose epidermis too, endothecium cells with secondary parietal thickenings, two middle layers and binucleate tapetum. The only pistil presented an ovary wall with nectariferous tissue and a meristematic ventral epidermis, a solid style and an inconspicuous stigma. The ovules were anatropous, bitegmic and crassinucelate and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Metrodorea nigra; Rutaceae; Blossom; Anthesis; Protandry; Flower structure.
