Coffee (Coffea arabica L.)

2014
Coffee (Coffea sp.) is a perennial plant widely cultivated in many tropical countries. It is a cash crop for millions of small farmers in these areas. As for other tree species, coffee has long breeding cycles, which makes conventional breeding programs time-consuming.

Lipoxygenase Distribution in Coffee ( Coffea arabica L.) Berries

Journal of Agricultural and Food Chemistry, 2007
In 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 ...

Cafe Arabica Coffea arabica L.

2018
Somatic embryogenesis is a technique that has been used in Central America for the multiplication of Coffea arabica F1 hybrids since its creation. The coffee breeding program for Central America—PROMECAFE (1992–2006)–was implemented with the participation of CATIE, CIRAD and the coffee institutes in the region.

Endophytic bacteria inCoffea arabica L.

Journal of Basic Microbiology, 2005
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative.

Ethylene-induced fruit ripening in arabica coffee (Coffea arabica L.)

Australian Journal of Experimental Agriculture, 1992
The effects of ethephon on arabica coffee (Coffea arabica L.) were tested in experiments conducted over 2 years in North Queensland. Rates tested were 0, 125, 250, 500, 750, 1000, 1500, and 2000 mgkg, applied when 15-20% (early treatment) or 45-50% (late treatment) of fruit were coloured.

Microsatellites in Coffea Arabica L.

2000
DNA polymorphism has became a widespread tool in biotechnology; in fact, they are frequently used for a number of technical approaches as, for example, in agronomic traits identification, variety characterisation, and marker-assisted breeding programmes.

Molecular Breeding in Coffee (Coffea Arabica L.)

2000
The 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).

Evaluation of Arabica Coffee (Coffea arabica L.) Genotypes for Biometrical Traits

Madras Agricultural Journal, 2013
An experiment on arabica coffee (Coffea arabica L.) genotypes for biometrical traits evaluation was carried out at Chettalli in Karnataka during the period 2004 - 2007 to study the variation in the vegetative and yield component traits. Eighty five genotypes exhibited significant variation for all the traits in three seasons of the study.
