Description : Banana and plantain (Musa spp) are important foreign exchange earners in Guyana and the Windward Islands of the Caribbean. Black Sigatoka Disease (BSD) also referred to as black leaf streak disease is one of the most destructive diseases of banana and plantain and is present within the region. In Guyana within two years following its introduction in 2008, the industry was totally decimated, recording a 100% decline, turning the country to a net banana importer. Also, from 2009 ? 2012 the disease spread in the Windward Islands causing as much as 100% decrease in the export of banana. The disease is caused by the ascomycete fungus, Mycosphaerella fijiensis (anamorph Pseudocercospora fijiensis) and is aggressive, challenging to control and results in enormous crop damage if left uncontrolled. In an effort to develop an integrated management approach to the disease the Caribbean Agricultural Research and Development Institute (CARDI) with financial assistance from the Caribbean Development Bank (CDB) is evaluating five FHIA banana and plantain accessions and eight IITA plantain accessions for tolerance to BSD. The evaluation is presently conducted in four Caribbean countries, Dominica, Guyana, St Lucia and St Vincent and the Grenadines. In each country, four distinct agro- ecological zones were selected for the trial evaluation blocks and using a randomized block design, four blocks were established in each country. Five FHIA accessions: FHIA-01, FHIA-03, FHIA-18, FHIA-21 and FHIA-23 are being evaluated in Dominica, St Lucia and St Vincent and the Grenadines whereas, plantain accessions: PITA-17, PITA-21, PITA-22, PITA-23, PITA-24 and PITA-26 are to be evaluated in Guyana for tolerance to the disease. Cavendish are used as regional controls and as borders rows to increase disease pressure. The disease parameters evaluated are youngest leaf spotted (YLS), disease development time (DDT), leaf emission rate (LER), disease severity at 6 months, bunch emergence and harvest, and index of standing leaves. Agronomic data; days from planting to flowering, bunch weight, number of hands in bunch, average weight of hands and average number of fingers per hand and bunch, as well as organoleptic characteristics of both cooked and ripe fruits are also evaluated. The early data collection, of the FHIA only accessions, show trends in the disease tolerance and agronomic performance as well as their adaptability in the different agro-ecological zone. The trends indicate better disease tolerance of FHIA varieties with higher leaf counts before, at bunching and at harvest. The organoleptic test shows a preference to FHIA 03 and FHIA 21. La banane et le plantain (espèces de Musa) sont les acquéreurs de devises étrangères importants en Guyane et en Îles du Vent des Caraïbe. La maladie noire de Sigatoka (schéma) également désignée sous le nom de la maladie noire de filet de feuille est l'une des maladies les plus destructives de la banane et du plantain et est présente dans la région. En Guyane dans un délai de deux ans après son introduction en 2008, l'industrie a été totalement décimée, enregistrant une baisse de 100%, tournant le pays à un importateur net de banane. En outre, à partir de 2009-2012 la propagation de maladie en Îles du Vent causant pas moins de la diminution de 100% de l'exportation de la banane. La maladie est provoquée par le champignon d'ascomycète, fijiensis de Mycosphaerella (fijiensis anamorph de Pseudocercospora) et est agressive, contestant pour commander et les résultats dans l'énorme culture endommagent si laissé incontrôlé. Dans un effort de développer une approche intégrée de gestion à la maladie l'institut agricole des Caraïbes de recherche et développement (CARDI) avec l'aide financière de la banque de développement des Caraïbes (BDC) évalue des adhésions de banane et de plantain de cinq FHIA et huit adhésions de plantain d'IITA pour la tolérance au schéma. L'évaluation est actuellement effectuée quatre pays des Caraïbes, Dominique, Guyane, St Lucia et Saint-Vincent-et-les Grenadines. Dans chaque pays, quatre agro zones écologiques distinctes ont été sélectionnées pour les blocs d'essai d'évaluation et employant une conception de bloc randomisé, quatre blocs ont été établis dans chaque pays. Cinq adhésions de FHIA : FHIA-01, FHIA-03, FHIA-18, FHIA-21 et FHIA-23 sont évalués en Dominique, au St Lucia et au Saint-Vincent-et-les Grenadines tandis que, des adhésions de plantain : PITA-17, PITA-21, PITA-22, PITA-23, PITA-24 et PITA-26 doivent être évalués en Guyane pour la tolérance à la maladie. Cavendish sont employés en tant que contrôles régionaux et comme rangées de frontières pour augmenter la pression de la maladie. Les paramètres de la maladie évalués sont la plus jeune feuille repérée (YLS), le temps d'élaboration de la maladie (DDT), le taux d'émission de feuille (LER), la sévérité de la maladie à 6 mois, émergences et récoltes de groupe, et index des feuilles debout. Données agronomiques ; des jours de la plantation à la floraison, du poids de groupe, nombre de mains dans le poids de groupe et moyen des mains et du nombre moyen de doigts par main et groupe, aussi bien que les caractéristiques organoleptiques des fruits cuits et mûrs sont également évalués. La collecte de données tôt, des adhésions de FHIA seulement, exposition tend dans la tolérance de maladie et la représentation agronomique aussi bien que leur adaptabilité dans la zone agro-écologique différente. Les tendances indiquent qu'une meilleure tolérance de maladie des variétés de FHIA avec une plus haute feuille compte avant, à se rassembler et à la récolte. L'essai organoleptique montre une préférence à FHIA 03 et à FHIA 21.

Description : The Sargassum seaweed [Sargassum natans and S. fluitans] can be classed as a perennial invasive weed problem in all the Caribbean islands. It has been shown to affect fisher-folks, sea bathers, and tourists. It is proving to be costly to remove; in addition to its offensive odour which hampers the clean-up operations. The University of Trinidad and Tobago at the BAFT campus is engaged in series of activities to find suitable uses of the seaweed as animal feed, and as soil medium and ameliorant. This study aimed at evaluating the suitability of the seaweed as a growing media for the production of sweet peppers [Capsicum annuum var. annuum] using different percentage of the weed (0, 25, 50 and 100%) with soil under greenhouse conditions. The crop growth and development and yield were monitored. The results indicated that the plant height [Y pl ht = 16.6 + 0.3 DAT - 0.11 TRT] and leaf number [Y no.lvs = 0.90 + 1.04 DAT - 0.206 TRT] increased as age of the crop increased, but decreased with the increase in percentage of seaweed/ soil mixture. A similar response was observed for the flower buds and fruits numbers and percentage soil mixture. The medium had no effect on the crop transpiration and net photosynthesis rate [PN] , photosynthesis active radiation[PAR] , and stomatal conductance. A nutrient analysis of the medium was also conducted.

Description : Crop nutrient management is a critical component of productivity and quality. Commercial horticulture has relied almost exclusively on inorganic nutrient sources to satisfy plant nutritional requirements. Compost tea represents a sustainable alternative technology but its use has not been extensively researched. A factorial experiment was conducted subjecting lettuce plants to four increasing concentrations of compost tea; 0, 5, 10 and 20 % (m/v) applied at either 100 or 200 cm3 plant-1 day-1, for 30 days. At the end of the trial, measurements were made of leaf area (LA), yield, shoot and root dry mass (DM), root to shoot ratio, and nitrogen (N) and phosphorus (P) contents of shoots and roots. Compost tea concentration significantly (P < 0.05) affected all growth indices showing a similar pattern. Increasing concentration up to 10 % (m/v), positively improved growth and yield above the control. Increasing further to 20 % (m/v) reduced LA, yield and dry mass. For these variables, applying compost tea at 200 cm3 plant-1 day-1 resulted in a better response. Increasing concentration of compost tea showed a directly proportional relationship to shoot and root N content. However, the effect was non-significant for P. Yield and shoot DM were affected by the combination of compost tea concentration and application rate. Similar patterns of increasing yield were seen for increasing concentration within both rates however, the differences were significant for all concentrations at the higher application rate. Application of 200 cm3, 5 % compost tea resulted in the greatest yield, shoot and root DM. In addition to root DM, root surface area was significantly correlated with yield and shoot DM. Compost tea used at appropriate concentrations improved root growth and lettuce productivity.

Résumé : Growth defense tradeoff theory predicts that plants in low-resource habitats invest more energy in defense mechanisms against natural enemies than growth, whereas plants in high-resource habitats can afford higher leaf loss rates. A less-studied defense against herbivores involves the synchrony of leaf production, which can be an effective defense strategy if leaf biomass production exceeds the capacity of consumption by insects. The aim of this study was to determine whether leaf synchrony varied across habitats with different available resources and whether insects were able to track young leaf production among tree habitat specialists in a tropical forest of French Guiana. We predicted that high-resource habitats would exhibit more synchrony in leaf production due to the low cost and investment to replace leaf tissue. We also expected closer patterns of leaf synchrony and herbivory within related species, assuming that they shared herbivores. We simultaneously monitored leaf production and herbivory rates of five pairs of tree species, each composed of a specialist of terra firme or white-sand forests within the same lineage. Our prediction was not supported by the strong interaction of habitat and lineage for leaf synchrony within individuals of the same species; although habitat specialists differed in leaf synchrony within four of five lineages, the direction of the effect was variable. All species showed short time lags for the correlation between leaf production and herbivory, suggesting that insects are tightly tracking leaf production, especially for the most synchronous species. Leaf synchrony may provide an important escape defense against herbivores, and its expression appears to be constrained by both evolutionary history and environmental factors.

Résumé : This label was created on October 20th 1900. Around the turn of the 20th century, cigars were advertised and sold mainly by the colourful, intricate labels that adorned the boxes. Intense competition encouraged manufacturers to see who could create the most beautiful, eye-catching labels. A diffrent stone was required to print each colour. It was not unusual for as many as 20 stones to be used to create a single label. The register for each printing had to be perfect. The process became known as STONE LITHOGRAPHY or CHROMOLITHOGRAPHY. Once this exacting printing process was completed, the labels were then gilded with hand-applied gold leaf. Finally, the labels were embossed using huge 30-ton presses. According to Joe Davidson, the eminent American art dealer and collector, the "Golden Era" of cigar labels is associated with the introduction of gilding and embossing in the 1890's up to the late 1920's when the less attractive full-colour or photo-mechanical labels began to appear. Genuine gold leaf was used primarily by German and Cuban printers and "bronzing" in which bronze powder was mixed with lacquer or sizing, applied like ink, then burnished with brushes or polished rollers to make them gleam like gold. These particular labels were produced by the German factory, Gerhard Meinesz in Bentheim, near the Dutch border, and closed in 1932. The labels were used during the 1920's. These spectacular lithographs lithographs wound up lying unused and undiscovered for generations. Because they were printed on special long-fibre, acid-free rage paper, these old labels retained their original brilliant colours. Consequently, they are available in very limited quantities.

Résumé : Verso of; Stachelberg's Havana Selection; Made in Tampa. Label 7439 4 plates
Cuban cigars had always enjoyed an enviable reputation among connoisseur smokers throughout the world, but they posed no particular threat to the American cigar market since a high tariff on Cuban cigars (but not tobacco leaf) made them too expensive for the average smoker. The Cuban province of Pinar del Rio and a region known as Vuelta Abajo were famous for growing a light colored tobacco leaf, the superb smoking ingredient of the famous clear Havana cigars. After 1868, Cuban tobacco was shipped in large quantities to the United States, where it was hand rolled into cigars by skilled Cuban artisans, revolutionizing the smoking habits and tastes of America.

Résumé : Functional aspects of biodiversity were investigated in a lowland tropical rainforest in French Guyana (5°2'N, annual precipitation 2200 mm). We assessed leaf '15N as a presumptive indicator of symbiotic N2 fixation, and leaf and wood cellulose '13C as an indicator of leaf intrinsic water-use efficiency (CO2 assimilation rate/leaf conductance for water vapour) in dominant trees of 21 species selected for their representativeness in the forest cover, their ecological strategy (pioneers or late successional stage species, shade tolerance) or their potential ability for N2 fixation. Similar measurements were made in trees of native species growing in a nearby plantation after severe perturbation (clear cutting, mechanical soil disturbance). Bulk soil '15N was spatially quite uniform in the forest (range 3-5‰), whereas average leaf '15N ranged from m0.3‰ to 3.5‰ in the different species. Three species only, Diplotropis purpurea, Recordoxylon speciosum (Fabaceae), and Sclerolobium melinonii (Caesalpiniaceae), had root bacterial nodules, which was also associated with leaf N concentrations higher than 20 mg gm1. Although nodulated trees displayed significantly lower leaf '15N values than non-nodulated trees, leaf '15N did not prove a straightforward indicator of symbiotic fixation, since there was a clear overlap of '15N values for nodulated and non-nodulated species at the lower end of the '15N range. Perturbation did not markedly affect the difference '15Nsoil m '15Nleaf, and thus the isotopic data provide no evidence of an alteration in the different N acquisition patterns. Extremely large interspecific differences in sunlit leaf '13C were observed in the forest (average values from m31.4 to m26.7‰), corresponding to intrinsic water-use efficiencies (ratio CO2 assimilation rate/leaf conductance for water vapour) varying over a threefold range. Wood cellulose '13C was positively related to total leaf '13C, the former values being 2-3‰ higher than the latter ones. Leaf '13C was not related to leaf '15N at either intraspecific or interspecific levels. '13C of sunlit leaves was highest in shade hemitolerant emergent species and was lower in heliophilic, but also in shade-tolerant species. For a given species, leaf '13C did not differ between the pristine forest and the disturbed plantation conditions. Our results are not in accord with the concept of existence of functional types of species characterized by common suites of traits underlying niche differentiation; rather, they support the hypothesis that each trait leads to a separate grouping of species.
