Source-sink manipulations in Coffea arabica L. and its effect on growth of shoots and root system Manipulação da relação fonte-dreno em Coffea arabica L. e seu efeito no crescimento da parte aérea e do sistema radicular

Ciência e Agrotecnologia, 2011
This paper investigated changes in growth and carbohydrate content of shoots and root systems in response to source-sink manipulation in field-grown coffee trees. The source-sink manipulations were carried out using manual de-fruiting. Two plots of trees

Genetic diversity among coffee tree progenies Big Coffee VL based on growth traits and production

Genetics and Molecular Research, 2016
In a coffee plantation of a coffee 'Acaiá' cultivar (Coffea arabica), on the Midwest of Minas Gerais in Capitólio city, a different kind of coffee tree was found (1989), possibly due to a mutation. It presented larger leaves and grains than those of conventional coffee trees and was named as "Big Coffee VL." The aim of this study was to estimate the ...

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Tree diversity on sustainably certified and conventional coffee farms in Central America [PDF]

, 2015
Shade coffee agroforestry systems have the potential to support biodiversity. Sustainable certification of coffee has been promoted as a means to provide incentives to maintain these systems, but as yet there is little evidence if this is effective.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Economical–epidemiological analysis of the coffee trees rust pandemic

Chaos: An Interdisciplinary Journal of Nonlinear Science
Coffee leaf rust is a prevalent botanical disease that causes a worldwide reduction in coffee supply and its quality, leading to immense economic losses. While several pandemic intervention policies (PIPs) for tackling this rust pandemic are commercially available, they seem to provide only partial epidemiological relief for farmers.
