RNA-Seq analysis and de novo transcriptome assembly of Coffea arabica and Coffea eugenioides : P0068 [PDF]

, 2013
Coffee is one of the most important agricultural commodites in the world. Coffea arabica, an allotetraploid from a recent hybridization of two diploid species (C.canephora and C.eugenioides) is responsible for 70% of world commercial production.

Methane Emissions From Flame Curtain Pyrolysis (Kon‐Tiki)

GCB Bioenergy, Volume 18, Issue 4, April 2026.
Flame curtain pyrolysis enables decentralized biochar production, but its net climate benefit depends on the magnitude of methane emissions caused during production. Methane emissions were below 5 g CH4 kg−1 biochar for dry feedstocks but increased for moist feedstocks. Pyrolysis emitted less methane than open burning of wheat straw. ABSTRACT Pyrogenic

Sensory Perception of Visually Impaired People Focused on Descriptive Sensory Analysis of Cosmetic Products

Journal of Sensory Studies, Volume 41, Issue 2, April 2026.
ABSTRACT Some researchers suggest visually impaired people's advantage in performing touch tests reflects not increased sensitivity, but the fact of being attentive to cues normally ignored by sighted people with regular vision or the more efficient use of sensory strategies.

Soil organic matter and F1 hybrid cultivar influence Coffea arabica yields in south‐central Guatemala

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Smallholders produce 60% of global coffee (Coffea arabica) supply but lack recommendations on nutrient management. We tested hypothesized N‐ and K‐driven yield gaps using on‐farm omission trials established across 21 fields in Guatemala. The effects of a single and combined application of N (285 kg ha−1) and K (350 kg ha−1) were evaluated for ...

Chemical Composition of Coffea arabica Beans and Grafts at Different Roasting Levels

Beverages
The main commercial species of coffee is Coffea arabica; however, it is highly susceptible to biotic and abiotic factors. For this reason, scions of Coffea arabica species are used on robusta (Coffea canephora) rootstocks since grafting can modify the ...

Growth, production, and bean quality of Coffea arabica as affected by interspecific grafting : Consequences for rootstock breeding [PDF]

, 2001
In order to avoid nematode damage to roots of Coffea arabica L. in Latin America, a common practice is interspecific grafting on C. canephora var. Robusta (Pierre) rootstocks. The performance of two C.

Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee

Chemie Ingenieur Technik, Volume 98, Issue 3, Page 85-97, March 2026.
Chlorogenic acid (CGA) concentration in coffee was predicted using mid‐infrared (MIR) spectroscopy and a machine learning approach. Forty‐four roasting stages (140–220 °C) plus a green coffee control were analyzed. A multilayer perceptron regressor, trained on preprocessed MIR data, outperformed traditional peak analysis, enabling accurate and ...
