O objetivo deste trabalho foi avaliar o crescimento vegetativo de cultivares clonais de Coffea canephora no sistema irrigado e não irrigado, nos períodos de estiagem e das chuvas, em Rio Branco, Acre. O experimento foi conduzido na Embrapa Acre. O delineamento experimental foi em blocos casualizados, em parcelas subsubdivididas. As variáveis avalia...
ABSTRACT: The cryopreservation of plant germplasm at ultralow temperatures is an alternative technique for the long-term storage of seeds of the genus Coffea sp. However, for this technique to be successful, cell integrity must be maintained at all stages of the process on the basis of scientific research. The present study investigated validated c...
Water availability, light, management practices, and harvest time impacts on Coffea arabica L. yield and bean quality remain uncertain. It was hypothesized that the soil water and light availability could impact berry distribution, yield, and bean chemical attributes within the plant canopy. Therefore, it was aimed to study berry yield, berry distr...
The quantification of electromagnetic energy exchanged between plants and their environments is important for ecophysiological studies. Measurement techniques have been developed for the determination of these changes in different spatial scales. In the literature are found some studies describing the use of devices carrying radiometers rotating ar...

La caféine est le psychostimulant le plus consommé au monde, et on peut supposer que la plupart des patients d’une officine en consomment. Sa consommation est associée à celle d’autres substances comme la nicotine et l’alcool, qui sont concernées par des campagnes de santé publique largement relayées dans le contexte officinal. Sa consommation est ...
La récente mise au jour d’un fonds d’archives privées tiré d’un vieux grenier d’un logis d’Angoumois donne à voir l’itinéraire d’un Saintongeais devenu capitaine de navires et planteur de café à Saint-Domingue : Jean-Baptiste Georgeon.Rares sont les personnalités de cette étoffe connue pour l’arrière-pays de Saintonge-Angoumois. Plus courantes sont...
Contextualization: For more than a century, coffee has been the main product of the national economy, also the one that has had the greatest incidence in the socioeconomic development of Colombia; for this reason, it is relevant to check up the biotic and abiotic factors that affect coffee production, especially in the department of Norte de Santan...
The main objective of this study is to analyze the problem of climate change and the effects that it can bring to coffee production at the national level, added to the problems that concern this productive sector. The methodology used consisted of the analysis of documents on climate change and coffee production worldwide. In turn, the main produci...
