Floral development in Potamogeton (Potamogetonaceae, Alismatales) with emphasis on gynoecial features
(Elsevier B.V., 2012-07-01)
The floral developmental patterns and carpel morphologies of Potamogeton illinoensis Morong, P. polygonus Cham. et Schltdl and P. pusillus L were investigated under light (LM) and scanning electron microscopes (SEM) to ...

Gynoecium with carpel dimorphism in Tricomaria usillo, comparison with other genera of the Carolus clade (Malpighiaceae)
(Springer Wien, 2019-04-05)
We analyzed the gynoecium morphology and anatomy of Tricomaria usillo in young and mature flowers from diverse populations in order to analyze the differentiation of structure and function of the parts of the carpel. We ...
Floral vasculature and its variation for carpellary supply in Anthurium (Araceae, Alismatales)
(2017-01-01)
Introduction and Aims. Anthurium is the largest genus of Araceae, with 950 species distributed in the neotropics. Despite the great diversity of the genus, the knowledge of its floral vasculature is based on observations ...
Floral development of the Ornithocephalus clade (Oncidiinae, Orchidaceae): The origin of the tabula infrastigmatica, gynostemium appendices and labellar callus
(2021-04-01)
The Ornithocephalus clade comprises small epiphytes distributed in 12 genera and c. 120 species. Their flowers have complex structures, the homologies of which are difficult to interpret. Through ontogenetic studies, we ...
Contribuições à taxonomia do complexo Chascolytrum subaristatum (Lam.) Desv. x Chascolytrum erectum (Lam.) Desv. (Poaceae, Pooideae, Poeae, Calothecinae)
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em AgrobiologiaCentro de Ciências Naturais e Exatas, 2023-02-09)
Despite a general morphological distinction within the Calothecinae subtribe, the taxonomy of
Chascolytrum is still challenging. The understanding of species in the genus has been
hampered, mainly, by the overlapping of ...
The importance of the period immediately preceding anthesis for grain weight determination in wheat
(Springer, 2001-05)
Although individual grain weight is an important source of variation for grain yield, there is still poor understanding of the causes determining final grain weight. Almost all studies conducted for understanding the ...
