Does thermal time for germination vary among populations of a tree legume (Peltophorum dubium)?

Braz. j. biol; 76 (3), 2016
Abstract Few works report the use of degree-days (DD) – used in crops to predict events and schedule management activities – to describe the germination of tropical trees. The cardinal temperatures (base, optimum and ceiling temperature) for germination of the species may vary depending on th...

Insect galls of Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ)

Braz. j. biol; 76 (3), 2016
Abstract Thirty-one morphotypes of insect galls and two flower damages were found on 16 families, 22 genera and 24 plant species in Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ). Fabaceae and Myrtaceae were the plant families with the greatest richness of insect galls (4 and 6 morphotype...

Evaluación de la actividad antiproliferativa de extractos metanólicos de plantas de la familia leguminosae
Evaluation of the antiproliferative activity of methanolic extracts of plants from the Leguminosae family

Rev. cuba. plantas med; 21 (3), 2016
Introducción: la familia Leguminosae es rica en isoflavonoides y puede tener efecto anticáncer. Las especies panameñas de esta familia no han sido estudiadas para explorar su potencial en los cánceres de mamas y próstata, dos principales causas de mortalidad en la población adulta panameña. Objeti...

Seed colour affects light and temperature requirements during germination in two Lotus species (Fabaceae) of the Arabian subtropical deserts

Rev. biol. trop; 64 (2), 2016
AbstractHeterogeneity in seeds mostly occurs due to physiological, environmental and genetic factors, and these could affect seed dormancy and germination. Therefore, the aim of our study was to assess the effect of seed colour on germination behavior. For this, both light and temperature requirements we...

Resource allocation in Copaifera langsdorffii (Fabaceae): how supra-annual fruiting affects plant traits and herbivory?

Rev. biol. trop; 64 (2), 2016
AbstractPlants have limited resources to invest in reproduction, vegetative growth and defense against herbivorous. Trade-off in resources allocation promotes changes in plant traits that may affect higher trophic levels. In this study, we evaluated the trade-off effect between years of high and low frui...

SSR genetic diversity assessment of popular pigeonpea varieties in Malawi reveals unique fingerprints

Electron. j. biotechnol; 19 (3), 2016
Background: Pigeonpea (Cajanus cajan (L.) Millsp.) is a drought tolerant legume of the Fabaceae family and the only cultivated species in the genus Cajanus. It is mainly cultivated in the semi-arid tropics of Asia and Oceania, Africa and America. In Malawi, it is grown as a source of food and income and ...

Hambúrgueres adicionados de farinha de alfarroba (Ceratonia siliqua) como antioxidante natura
Hamburgers added carob flour (Ceratonia siliqua) as a natural antioxidant

Hig. aliment; 30 (252/253), 2016
Este trabalho teve como objetivo avaliar a adição da farinha de alfarroba como antioxidante em hambúrgueres. Foram elaboradas quatro formulações de hambúrgueres: controle, com 0,1% de antioxidante sintético (BHT) e duas com farinha de alfarroba (2% e 4%), respectivamente. Foram realizadas análise...

Anthelmintic activity of Leucaena leucocephala protein extracts on Haemonchus contortus

Abstract The objective of this study was to evaluate the effects of protein extracts obtained from the plant Leucaena leucocephala on the nematode parasite Haemonchus contortus. The seeds, shell and cotyledon of L. leucocephala were separated and their proteins extracted using a sodium phosphate buffer, ...

Seed predation food web, nutrient availability, and impact on the seed germination of Senegalia tenuifolia (Fabaceae)

Rev. biol. trop; 63 (4), 2015
Abstract:Food web studies, which include qualitative and quantitative information about species interactions for all trophic levels in a specific community, are important tools to characterize the community structure, and to understand the role of species interaction in natural communities. With this aim...

Plantas medicinais como alternativa terapêutica para aumento da resistência imunológica

The immune system modulation in disease prevention and treatment has been the subject of interest for many years, so that many studies have emphasized the immunomodulatory drugs research, especially from natural origin. So, in order to provide a current information source, this paper presents a review of...
