EFEITO DE FUNGICIDAS NO CAFEEIRO CONILON [PDF]

Nativa, 2018
O objetivo foi avaliar o efeito de fungicidas no controle da ferrugem, no crescimento vegetativo e reprodutivo do café conilon. O delineamento experimental utilizado foi em blocos casualizados com seis tratamentos e quatro repetições (duas aplicações de piraclostrobina e epoxiconazol + boscalida e duas aplicações de piraclostrobina e epoxiconazol - T1;

Climate favourability to leaf rust in Conilon coffee [PDF]

Australasian Plant Pathology, 2012
The Brazil is the second largest producer of Conilon coffee (Coffea canephora), being the state of Espirito Santo responsible for producing 9.7 million bags of Conilon coffee. The biology of Hemileia vastatrix, etiologic agent of leaf rust, the main disease of this culture, is not well understood under the environmental conditions of Espirito Santo ...

Selection and Characterization of Non-Saccharomyces Yeast Strains for Potential Use in Arabica and Conilon Coffee Fermentations. [PDF]

J Food Sci
ABSTRACT Customized fermentation approaches are necessary due to the differences in the characteristics of Coffea arabica (Arabica) and Coffea canephora (Conilon) coffees. Therefore, this work aimed to select and characterize new non‐Saccharomyces yeast strains with potential use as starter cultures for Arabica and Conilon coffee fermentation, using a ...

Efficiency and response of conilon coffee genotypes to nitrogen supply [PDF]

African Journal of Biotechnology, 2016
The objective of the study was to differentiate genotypes with higher efficiency and responsiveness to nitrogen supply, to understand how the nitrogen supply can impact the dry matter allocation and the accumulation of this nutrient in the different plant compartments of genotypes of conilon coffee, cultivated under contrasting conditions of nitrogen ...

Potential beverage quality of three wild coffee species (Coffea brevipes, C. congensis and C. stenophylla) and consideration of their agronomic use

Journal of the Science of Food and Agriculture, Volume 103, Issue 7, Page 3602-3612, May 2023., 2023
Abstract BACKGROUND Of the 130 known coffee (Coffea) species, very few have been properly evaluated for their beverage quality. The diversity of wild coffee species is considered critical to the long‐term sustainability of the coffee sector, particularly under climate change.

Comparison of chemical compositions, antioxidant activities, and acetylcholinesterase inhibitory activities between coffee flowers and leaves as potential novel foods

Food Science &Nutrition, Volume 11, Issue 2, Page 917-929, February 2023., 2023
The chemical compositions of coffee flowers and leaves Arabic Coffea from Yunnan province, China were compared with green coffee beans by HPLC–MS and GC–MS. Antioxidant and acetylcholinesterase inhibitory activities were higher than green coffee beans in vitro. Thirty differentially changed chemical compositions were confirmed.

Intraspecific variation in growth response to drought stress across geographic locations and genetic groups in Coffea canephora

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
Drought tolerance within C. canephora is negatively linked to growth. Drought tolerance of Uganda's C. canephora is weakly though significantly linked to the local climate. Intraspecific diversity, associated with adaptation to local conditions, can be exploited in breeding for climate‐resilient cultivars.

ASPECTOS FISIOLÓGICOS DO CAFEEIRO CONILON: UMA ABORDAGEM SISTEMÁTICA [PDF]

Nucleus, 2011
The first commercial crops Conilon Coffee (Coffea canephora) were implanted from the 50's, aiming to cultivate marginal areas to the Arabica coffee (Coffea arabica). Actually conilon represents a significant portion of the coffee market. Nevertheless, it
