ELUCIDATING ENIGMATIC FLORAL ISSUES IN COPAIFERA LANGSDORFFII DESF. (LEGUMINOSAE, CAESALPINIOIDEAE)
(UNIV CHICAGO PRESS, 2010)
This study focuses on the floral development of Copaifera langsdorffii to elucidate uncertain features in its floral morphology, such as the tetramerous calyx, lack of petals, blackened anthers and their supposed sterility, ...
Floral development in the tribe Cedreleae (Meliaceae, sub-family Swietenioideae): Cedrela and Toona
(OXFORD UNIV PRESS, 2008)
Background and Aims Floral development of Cedrela and Toona, the genera comprising the basal tribe Cedreleae of the sub-family Swietenioideae of Meliaceae, is described. The focus was on three endangered, ecologically and ...
A influência da morfologia e da biologia floral no sucesso reprodutivo do adubo verde Crotalaria juncea L. (Leguminosae, Papilionoideae)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Agricultura e Ambiente (Campus ARARAS)Câmpus Araras, 2017-02-06)
The pollination is a fundamental ecosystem function for the plants development, including the reproductive success. In Crotalaria juncea L., it is verified that the flowers have distinct anthers morphs and fillets length, ...
Floral development and vascularization help to explain merism evolution in Paepalanthus (Eriocaulaceae, Poales)
Background. Flowers in Eriocaulaceae, a monocot family that is highly diversified in Brazil, are generally trimerous, but dimerous flowers occur in Paepalanthus and a few other genera. The floral merism in an evolutionary ...
Foliar damage modifies floral attractiveness to pollinators in Alstroemeria exerens
Pollination is a requisite for sexual reproduction in plants and its success may determine the reproductive output of individuals. Pollinator preference for some floral designs or displays that are lacking or poorly developed ...
COMPARATIVE FLORAL ANATOMY AND DEVELOPMENT IN NEOTROPICAL LAURACEAE
(Univ Chicago Press, 2016-09-01)
Premise of research. The pantropical magnoliid family Lauraceae has an extensive macrofossil record that dates back to the Early Cretaceous. However, flower anatomy among extant species is relatively poorly known. We ...
