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).

Latent Infection in Coffea arabica L.

Nature, 1948
PROF. S. R. BOSE‘S article1 dealing with the occurrence of Phomopsis casuarince F. Tassi throughout the tissues of Casuarina equisetifolia Forst. prompts me to record some observations made in 1940 and 1941 on the presence of various fungi in the tissues of Arabic coffee (Coffea arabica L.).

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.

Histology of somatic embryogenesis in Coffea arabica L.

Biologia, 2018
The objective of this study was to characterize the histodifferentiation of somatic embryogenesis obtained from leaf explants of C. arabica. Therefore, we histologically analyzed the respective stages of the process: leaf segments at 0, 4, 7, 15 and 30 days of cultivation, Type 1 primary calli (primary calli with embryogenic competence) and 2 (primary ...

Water movement in coffee seedlings (Coffea arabica L.)

Oecologia, 1977
Various resistances through the soil-plant-atmosphere continuum were measured in order to find which resistance is mainly responsible for the low leaf water potential reported in coffee plants, especially when water supply is plentiful. Roots appeared to offer a major resistance in this pathway. At least under the experimental conditions mentioned here
