Growth, morphological, metabolic and photosynthetic responses of clones of eucalyptus to glyphosate
Cerveira Junior, Wilson Roberto; Costa, Yanna Karoline Santos da ; Carbonari, Caio Antonio ; ; Alves, Pedro Luis da Costa Aguiar ; Carvalho, Leonardo Bianco de (Forest Ecology and Management, 2020) [Artigo]
We hypothesized that eucalyptus has clone-dependent responses to glyphosate, and such differential responses might be associated with morphological, metabolic and/or photosynthetic changes. Experiments were carried out ... -
Response of Corn Seedlings (Zea mays L.) to Different Concentrations of Nitrogen in Absence and Presence of Silicon
da Silva, Edson Santos; de Mello Prado, Renato ; ; ; dos Santos, Durvalina Maria M. (Silicon, 2020) [Artigo]
Corn plants are highly demanding of nitrogen and the application of silicon has been studied because it minimizes stress from different natures, and for the better utilization of some nutrients by the plants. Thus, the ... -

At maximum vegetative growth, sprays with fungicide to control Asian rust (Phakopsora pachyrhizi Sydow and P. Sydow) should reach high canopy penetration and plant coverage. Therefore, the central objective of this study ... -
Additions to the knowledge of the pollen morphology of some Fabaceae from Cerrado forest patches of Brazil
Soares, Eduardo Lopes; ; Gasparino, Eduardo Custódio (Palynology, 2020) [Artigo]
This study presents the pollen morphology of 11 Brazilian native species and one variety of Caesalpinioideae and Detarioideae (Fabaceae) from forest patches of São Paulo, Brazil. The aim of this research is to expand the ... -
Silicon application induces changes C:N:P stoichiometry and enhances stoichiometric homeostasis of sorghum and sunflower plants under salt stress
Calero Hurtado, Alexander; Chiconato, Denise Aparecida ; Prado, Renato de Mello ; Sousa Junior, Gilmar da Silveira ; Olivera Viciedo, Dilier ; (Saudi Journal of Biological Sciences, 2020) [Artigo]
Beneficial effects of silicon (Si) on growth have been observed in some plant species, reportedly due to stoichiometric changes of C, N, and P. However, little is known about the effects on the stoichiometric relationships ... -
Size at onset of sexual maturity in macrobrachium amazonicum (Heller, 1862) phenotypes: An integrative approach
Paschoal, Lucas R. P.; Zara, Fernando J. (Anais da Academia Brasileira de Ciencias, 2020) [Artigo]
The size at the onset of sexual maturity (SOM) was determined in four hololimnetic populations of Macrobrachium amazonicum using morphometric, physiological and functional criteria. Male prawns from two populations analyzed ... -
Phenological diversity of maprounea guianensis (euphorbiaceae) in humid and dry neotropical forests
; ; ; ; Rossatto, Davi R.; ; (Australian Journal of Botany, 2020) [Artigo]
Phenological diversity, seasonality and leaf longevity may affect leaf habits, reflecting plant responses to environmental conditions. Maprounea guianensis Aubl. is a widespread species in Brazil that is associated with ... -

Aluminum-induced stomatal closure is related to low root hydraulic conductance and high ABA accumulation
Gavassi, Marina Alves; ; ; Silva, Giselle Schwab ; Carvalho, Rogério Falleiros ; Habermann, Gustavo (Environmental and Experimental Botany, 2020) [Artigo]
