Comparative effect of coffee robusta and coffee arabica (Qahwa) on memory and attention
Metabolic Brain Disease, 2018The comparative effects of coffee robusta and coffee arabica (Qahwa) on different attention and memory related assignments were measured in a double-blind study of 300 healthy young adult women who were randomly assigned to one of three different drinks: Group I (coffee robusta sachet dissolved in 100 ml of hot water): Group II (coffee arabica): and ...

Molecular Breeding in Coffee (Coffea Arabica L.)
2000The cultivated coffee Coffea arabica L. (2n=4x=44) is an allotetraploid species native to Africa, containing two diploid genomes that originated from two different diploid wild ancestors (2n=2x=22), C. canephora and C. eugenioides or ecotypes related to those species (Lashermes et al., 1999).

Arabica Coffee Production in Kenya: An Overview
Outlook on Agriculture, 1986Coffee is of basic importance to the Kenyan economy, producing about 30 per cent of the total foreign exchange earnings. In the 1960s severe losses from coffee berry disease led to the launching of an intensive breeding programme that has resulted in a new cultivar which is disease resistant, high yielding, and compact in growth and produces good ...

Developing varieties of Arabica coffee
2018About 60% of the annual world coffee production is harvested from Arabica (Coffea arabica) coffee, with the remainder harvested from Robusta (C. canephora) coffee. The former is superior in beverage quality, but more expensive to cultivate. The demand for quality coffees is steadily increasing, but anticipated climate change may jeopardize the ...

Lipoxygenase Distribution in Coffee ( Coffea arabica L.) Berries
Journal of Agricultural and Food Chemistry, 2007In this paper lipoxygenase (LOX) presence was investigated in coffee berries to determine its involvement in lipid degradative metabolism of plants grown in organic and conventional cultivations. An immunochemical analysis has evidenced a ca. 80 kDa protein, cross-reacting with an anti-LOX antibody, only in the pulp fraction of berries obtained from ...
