Growth and production of Heliconia under different light conditions
; Ono, Elizabeth Orika; ; ; ; ; (Semina:Ciencias Agrarias, 2017) [Artigo]
The use of shading screens of different colors can change the spectral quality of radiation and, as a consequence, the growth and production of crop plants. The aim of this study was to evaluate aspects of the growth, ... -
Floral biology, nectar secretion pattern and fruit set of a threatened Bignoniaceae tree from Brazilian tropical forest
Souza, Camila Vaz; ; Machado, Silvia Rodrigues ; Guimarães, Elza (Flora: Morphology, Distribution, Functional Ecology of Plants, 2017) [Artigo]
Zeyheria tuberculosa, a Bignoniaceae tree that occurs in a broad latitudinal range in Brazilian forests, is a threatened species of seasonal tropical forest. It is crucial to enhance the knowledge on this species’ floral ... -
Effect of mutualistic and antagonistic bees on floral resources and pollination of a savanna shrub
Quinalha, Marília Monteiro; Nogueira, Anselmo ; Ferreira, Gisela ; Guimarães, Elza (Flora: Morphology, Distribution, Functional Ecology of Plants, 2017) [Artigo]
Since Darwin, cheaters have been described in plant-pollinator mutualisms. Bignoniaceae species have a wide interaction network with floral visitors, and most of those interactions are established with cheaters. Thus, our ... -

; Martins, Dagoberto; Rodella, Roberto Antonio ; ; (Semina:Ciencias Agrarias, 2016) [Artigo]
The aim of this work was to evaluate the selectivity of herbicides applied in post-emergence on Zoysia japonica Steud (Poaceae) and determine associations with the leaf anatomy of this grass. The experimental design was ... -
Morphology, secretion composition, and ecological aspects of stipular colleters in Rubiaceae species from tropical forest and savanna
Tresmondi, Fernanda; ; Guimarães, Elza ; Machado, Silvia Rodrigues (Science of Nature, 2015) [Artigo]
Colleters are secretory structures that produce and release mucilage or a mucilage-resin mixture protecting meristems and young structures against desiccation, herbivores, and pathogens. The secretions may vary in colleters ... -
