Yunnan Coffea arabica L.

2021
As one of the three most popular drinks in the world, coffee is one of the commercial crops being researched in depth for its chemical components and bioactivities. In the past few years, Yunnan Coffea arabica (YAC) became an important agricultural crop, which has been developed rapidly, and the planting area has now reached 120,000 hectares.

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.

Linkage in Coffea arabica

Nature, 1961
THE anormalis factor (Am Am) of Coffea arabica affects the size of the plant, its branching habit and its leaves, flowers, fruits and seeds. The internodes of the branches are shorter than in the typica variety, taken as standard. The leaves are extremely abnormal, often almost palmate and of various sizes.

Shade adaptation of photosynthesis in Coffea arabica

Photosynthesis Research, 1984
The effect of irradiance on the rate of net photosynthesis was measured for mature leaves of coffee grown under five levels of radiation from 100% to 5% daylight. The rate of light-saturated photosynthesis per unit leaf area (PNmax) increased from 2 μmol CO2 m(-2) s(-1) under 5% daylight to 4.4 μmol CO2 m(-2) s(-1) under 100% daylight.

A novel type of somatic embryogenesis in Coffea arabica

Plant Cell Reports, 1992
A novel type of somatic embryogenesis characterized by an efficient and highly synchronized embryo formation was observed in embryogenic callus of Coffea arabica initiated on Murashige and Skoog medium containing kinetin (4 mg/l) and 2,4-D (1 mg/l). It occurs in suspension and goes along with the suppression of "High Frequency Somatic Embryo Induction"

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).

Phenotypic analysis of Coffea arabica accessions from Ethiopia: Contribution to the undestanding of Coffea arabica diversity [PDF]

open access: possible, 2008
As a consequence of Coffea arabica domestication process, the genetic diversity of cultivated genotypes of this species is extremely restricted. According to this observation, FAO organized, in 1964-1965, surveys of spontaneous and subspontaneous genotypes in the main center of origin (Ethiopia).

Standardization of homeopathic Coffea arabica (Coffea cruda) and Coffea tosta matrix tinctures

Pharmaceutical Chemistry Journal, 2008
Methods of standardization and quality control of homeopathic matrix tinctures of Coffea arabica and Coffea tosta obtained using green and roasted coffee beans are described. They include the organoleptic characteristics, qualitative reactions, TLC, quantitative estimation of caffeine and total phenolcarboxylic acids (calculated as caffeic acid ...
