Competition between trees in cocoa production remains a little studied area. The origin of this phenomenon, which has a strong impact on varietal selection, is often unknown. The aim of this study was to determine the factors of intraspecific competition on cocoa populations used in Côte d'Ivoire. The study was conducted in two cocoa plots monitore...
Article
In Central America, coffee is mainly grown in agroforestry systems. This practice modifies the microclimate, which, in turn, influences coffee growth and development. However, modeling these microclimate modifications is a challenge when trying to predict the development of a disease in the understory crop, based on variables usually monitored in w...

In West Africa, Harmattan-induced atmospheric and soil droughts represent seasonally recurring hazards for Theobroma cacao L. agro-ecosystems. Under the influence of the Harmattan winds, precipitation is impaired and air humidity and temperature reach stressful levels. Climate change is causing an increase in temperature that will drive up the evap...

Interactions between neighbouring plants in an ecosystem can lead to competition, even in single-species stands. Genetic selection of perennial plants based on the individual values of genotypes does not usually take into account interactions that develop over time. The purpose of this study was to ascertain whether the effects of competition might...
Article
Studying spatial and temporal plant disease dynamics helps to understand pathogen dispersal processes and improve disease control recommendations. In this study, three cacao plots devoid of primary inoculum of Phytophthora megakarya (causal agent of cacao black pod rot disease) upon establishment in 2006 were monitored for presence of disease on a...

• The African coffee white stem borer (CWSB) Monochamus leuconotus is a destructive pest of Arabica coffee in Africa. Documentation on outbreaks, spatiotemporal development and the relationship with different environmental conditions and coffee production system is limited. • To underpin effective control measures, we studied aspects of local and r...
Article
The coffee berry borer (CBB), Hypothenemus hampei (Ferrari), is a multivoltine species closely associated with coffee crops worldwide, causing severe damage to the bean. In Mexico, as in all tropical regions, CBB survives during the inter-harvest period in residual berries on the ground or in dry berries remaining on the branches, and then disperse...

Resumen La monilia (Moniliophthora roreri) es la principal enfermedad biótica de T. cacao en Colombia. Se requiere conocer aspectos básicos de la biología del patógeno para generar estrategias de manejo. Se analizó la diversidad genética y estructura poblacional de 186 aislamientos de M. roreri procedentes de siete departamentos de Colombia utiliza...
Article
Recycling empty fruit bunches (EFBs) in mature oil palm stands usually consists in distributing them over a limited area representing 3%–10% of the plot. The impact of this practice on soil quality, including soil biodiversity, is not well known at the plot scale. We analysed soil physical, chemical, and biological variables. Five zones were define...
Article
The African oil palm (Elaeis guineensis Jacq.) is grown on a total area of 16 million ha; but data on soil quality in mature oil palm plantations are fragmentary and data concerning biota are almost nonexistent. Consequently, no well-tested sampling method is available for soil diagnoses. We studied the spatial heterogeneity of the soil around the...

Despite the dramatic changes in land-use arising from expansion of the palm oil industry, soil biodiversity in oil palm plantations has been little investigated. The present study aims to assess the effect of organic waste recycling (empty fruit bunches, EFB) on soil biodiversity in a mature plantation in Sumatra, Indonesia. A chronosequence was de...

This study aims to establish if there is some sensory variability among fonio landraces. Fonio, the oldest indigenous and very tasty cereal growing in West Africa, is usually consumed as a couscous. Group interviews of consumers were conducted in Bamako, Mali to identify the main quality criteria of a cooked grain. Fonio grain must be swollen, not...
Article

This study was aimed at determining whether climatic conditions during bean development affected the chemical composition of the seed, the sensory perception of the coffee beverage and combinations of volatile compounds in green coffee. Using 16 experimental plots in Reunion Island displaying broad climatic variations, we showed that chlorogenic ac...

Sensory profiles of coffee in the Dominican Republic are linked to the terroirs Dominican coffee cultivation is changing. The institutional and private chain participants want to improve the marketing of their coffee. They would like to access the "specialty coffees" market, including the "coffee terroir" market, to give producers the opportunity o...
Article
The texture of 64 mangoes of different commercial varieties was analyzed by a trained sensory panel. The intensities of the characters “firmness,” “crunchiness,” “melting” and “juiciness” were noted from 0 to 10. Soluble solids content, visible/ NIR spectrum and texture of the same fruits were determined using instrumental methods. Texture was dete...
Article
Knowledge of the sensory diversity of a wide range of dessert bananas would be helpful in breeding programmes and so diversify the banana market. Descriptive sensory profiling was thus used to assess 13 cultivated bananas and four new triploid hybrids at an eating stage. A specific vocabulary was defined to describe the sensory traits of dessert ba...
Article
This paper describes the multidimensional features of the texture of cooked rice (in particular the visual aspect and mechanical attributes) determined by sensorial analysis and links these attributes with a wide range of physicochemical characteristics of raw grain (in particular certain cell wall components). Textural classes of cooked rice did n...

Consumers from developed nations accord a great deal of ethical consideration to their consumption options. They have shifted from environmental concerns to a socially based challenge. Many marketing studies have been carried out on such consumer behaviour indexed to ethics, but the consideration of ethical criteria in product choice is under-docum...

Husk tomato ( Physalis pubescens L.) is one of the important 100 species in the Physalis genus of the Solanaceae family. Among unexploited tropical fruits, Physalis is a very promising fruit. Physalis is included in the priority list of many governments' horticulture and fruit export plans. It is relatively unknown in importing markets and remains...
Article
Volatile compounds of cooked rice from scented (Aychade, Fidji) and nonscented (Ruille) cultivars grown in the Camargue area in France were compared to that of a marketed Asian scented one (Thai) by gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS). GC-O analyses of the organic extracts resulted in the percepti...

Coffee fruits grown in shade are characterized by larger bean size than those grown under full-sun conditions. The present study assessed the effects of shade on bean characteristics and sugar metabolism by analyzing tissue development, sugar contents, activities of sucrose metabolizing enzymes and expression of sucrose synthase-encoding genes in f...
Article
Volatile compounds from cured vanilla beans were extracted using organic solvents. Sensory analysis showed that the aromatic extract obtained with a pentane/ether (1/1 v/v) solvent mixture provided the extract most representative of vanilla bean flavour. Sixty-five volatiles were identified in a pentane/ether extract by GC–MS analysis. Aromatic aci...

Coffee quality, in the present context of overproduction worldwide, has to be considered as a main selection criterion for coffee improvement. After a definition of quality, and an overview of the non genetic factors affecting its variation, this review focuses on the genetic factors involved in the control of coffee quality variation. Regarding th...
Article
Naturalized cocoa populations originating from the Oyapok and Tanpok basins in French Guiana were studied for their technological characters (bean count, fat content, purine content) and sensory characters (overall aroma intensity, cocoa flavour, acidity, bitterness, astringency, fruity or floral tastes, aftertaste, etc.), along with three controls...

Effects of shade (50% light) condition on development and sugar metabolism was analyzed in fruits of Coffea arabica L. var. IAPAR 59. Fresh weight measurements of separated tissues (pericarp, perisperm and endosperm) showed that the increased size observed in beans of shaded plants was correlated with high perisperm development. Reducing sugar cont...
