“…Conversely, the number of secondary branches was greater in the dry season (June-November) ( figure 2). This result is in agreement with the phenology of Eugenia stipitata, which also exhibits higher vegetative growth during the rainy season than in the dry [25]. The result supports the hypothesis that apical dominance may be temporarily broken by water stress, encouraging the growth of secondary branches [17].…”

-Introduction. The branches of camu-camu should start sprouting from its base, in order to be positively related to a fruit yield increase. The objective of this study was to consider how plant growth and fruit yield varied according to the plantation type and crop management system. Materials and methods. The growth of the crown and fruit production under different types of plantations originating from cuttings, grafts or seedlings, and seed plantation management: fertilization, pruning and planting different densities, were compared. Results and discussion. Cutting plants formed more branches than those originating from grafting, regardless of the origin of the grafted scion. In seed plantations, zero fertilization and pruning had no effect on the formation of basal branches, but pruning delayed fruit production. Plantations with three plants per hole produced significantly greater numbers of basal branches, but further evaluation is necessary to analyze the effect of this on fruit production. Conclusion. Cutting plantations are technically more desirable than grafting ones because camu-camu trees have better branching from the base. In seed plantations, the selection of plants for their abundant branching from the base is technically feasible. In addition, planting three plants per hole seems promising for improving branching.Keywords: Brazil / Amazon / camu-camu / Myrciaria dubia / crop management / fruiting / plant growth form / pruning Résumé -Un plus grand nombre de branches permet-il d'améliorer le potentiel de production fruitière du camucamu ? Expérimentation de différents types de plantation et de gestion des cultures. Introduction. Pour être plus productives en fruits les branches du camucamu doivent partir de la base de la plante. L'objectif de cette étude était d'examiner comment la croissance des plantes et le rendement en fruits variaient selon le type de plantation et le système de gestion des cultures. Matériel et méthodes. Les paramètres de croissance de la couronne et de production de fruits ont été observés dans des plantations issues de plants bouturés, greffés ou de semis ; et dans la plantation issue de plants de semis, les effets de la fertilisation, de la taille et de la densité de peuplement ont été comparés. Résultats et discussion. Les plantes issues de bouturage ont formé plus de branches que celles provenant de greffage, indépendamment de l'origine du greffon. Dans les plantations issues de semis, l'absence de fertilisation et la taille n'ont eu aucun effet sur la formation de branches basales, bien que la taille a retardé la production de fruits. Les plantations avec trois plants par trou ont produit un nombre de branches basales significativement plus grand, mais une analyse plus approfondie de l'effet de ce traitement sur la production de fruits est nécessaire. Conclusion. Utiliser des plants bouturés est techniquement plus souhaitable que des plants greffés pour une meilleure ramification basale des camucamu. Dans les plantations issues de semis, la sélection des plant...

“…Cabe señalar que, en los últimos años, las instituciones han mostrado interés en el mejoramiento de la producción, y se realizan investigaciones sobre propagación, manejo, cosecha y poscosecha de ciertos frutales amazónicos, como arazá, borojó y naranjilla (Cuéllar, Ariza, Anzola, & Restrepo, 2013;Jiménez, Díaz & Sotelo, 2014;Ochoa & Ellis, 2002;Rincón & Garzón, 2012;Van Kanten & Beer, 2005), lo que nos indica la importancia que están adquiriendo estas especies en la Amazonía.…”

“…La mayoría de sus suelos presentan un complejo de infertilidad, por lo que conforman ecosistemas frágiles, propensos a degradarse a corto plazo cuando el bosque natural es reemplazado por sistemas de producción no sostenibles (Valarezo, 2012). La biodiversidad en los ecosistemas naturales de la región amazónica tiene un alto potencial para el desarrollo sostenible, cuando se integran los diferentes recursos de bosque y cultivos con los que cuenta el productor.…”

Los frutales en la región norte de la Amazonía se encuentran como parte de la diversidad de cultivos en las chakras de los productores. El objetivo del presente estudio fue caracterizar los frutales amazónicos presentes en las fincas productoras de cacao, café y sistemas silvopastoriles ubicadas en las provincias de Orellana y Sucumbíos La información se obtuvo en base a encuestas dirigidas y mediante observación directa en el campo. Los resultados indicaron que en las dos provincias, los productores establecen de 1 a 19 especies de frutales en sus parcelas, siendo las fincas de menos de 10 hectáreas las más diversas. En la mayoría de fincas, los frutales predominantes en los sistemas de producción son cítricos, coco, guaba, aguacate, papaya, piña y chonta. Estos cultivos se encuentran en asocio con café, cacao, sistemas silvopastoriles; monocultivos; o dispersos fuera de estos sistemas. Por otro lado, se han introducido especies que son consideradas como frutales con potencial de mercado, entre ellos se encontraron la grosella, higo, pomelo, mango y maracuyá. La producción de los frutales está destinada en su mayoría para autoconsumo y alimentación de los animales de la finca; sin embargo el excedente se vende para generar un ingreso económico.

Mitig Adapt Strateg Glob Change

Agroforestry (AF)-based adaptation to global climate change can consist of (1) reversal of negative trends in diverse tree cover as generic portfolio risk management strategy; (2) targeted, strategic, shift in resource capture (e.g. light, water) to adjust to changing conditions (e.g. lower or more variable rainfall, higher temperatures); (3) vegetation-based influences on rainfall patterns; or (4) adaptive, tactical, management of tree-crop interactions based on weather forecasts for the (next) growing season. Forty years ago, a tree physiological research tradition in aboveground and belowground resource capture was established with questions and methods on climate-tree-soil-crop interactions in space and time that are still relevant for today’s challenges. After summarising early research contributions, we review recent literature to assess current levels of uncertainty in climate adaptation assessments in and through AF. Quantification of microclimate within and around tree canopies showed a gap between standard climate station data (designed to avoid tree influences) and the actual climate in which crop and tree meristems or livestock operates in real-world AF. Where global scenario modelling of ‘macroclimate’ change in mean annual rainfall and temperature extrapolates from climate station conditions in past decades, it ignores microclimate effects of trees. There still is a shortage of long-term phenology records to analyse tree biological responses across a wide range of species to climate variability, especially where flowering and pollination matter. Physiological understanding can complement farmer knowledge and help guide policy decisions that allow AF solutions to emerge and tree germplasm to be adjusted for the growing conditions expected over the lifetime of a tree.
