Several alternatives are presented for gulupa production, the marketing process and export to Spain, based on descriptive and exploratory methods that involved the characterization, identification and situational analysis. ...
In vitro evaluation of commercial fungicides for control of Colletotrichum spp., in blackberryEvaluación in vitro de fungicidas comerciales para el control de Colletotrichum spp., en mora de castilla
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2013)
Efficiency in vitro of five chemical fungicides, three plant extracts and three biocontrol products were evaluated by their inhibition of mycelial growth percentage and inhibition of fungal biomass percentage, for Colletotrichum gloeosporioides strain 52 and Colletotrichum acutatum strain 168. In the group of chemical fungicides, the best results for inhibition of mycelial growth of both pathogens were obtained with ...
Alternate bearing and phenology of ‘Valencia’ orange (Citrus sinensis [L.] Osbeck) in the lowland wet tropics of ColombiaAlternancia de la producción y comportamiento fenológico de la naranja ‘Valencia’ (Citrus sinensis [L.] Osbeck) en el trópico bajo húmedo de Colombia
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2013)
In tropical conditions near the equatorial, precipitation is the main climatic factor that influences the growth and development of citrus plants. In a ‘Valencia’ orange orchard planted with 11-year-old trees located in the higher portion of the foothills of Corpoica, La Libertad Research Center in Villavicencio, Meta, Colombia, we recorded tree production data between the years 2008-2010. Information on the phenology ...
Integrated pest management as a strategy to control the passionfruit flower-bud fly, Dasiops inedulis Steyskal (Diptera: Lonchaeidae)Manejo integrado de plagas como estrategia para el control de la mosca del botón floral del maracuyá Dasiops inedulis Steyskal (Diptera: Lonchaeidae)
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2012)
En el presente estudio se colectaron cuatro parasitoides de Dasiops inedulis Steyskal (Diptera: Lonchaeidae), i.e., uno de tipo larva-pupa identificado como Utetes anastrephae (Viereck) (Hymenoptera: Braconidae), y tres parasitoides de pupas identificados como Pachycrepoideus vindemmiae Rondani, Spalangia sp. (Hymenoptera: Pteromalidae) y Aganaspis sp. (Hymenoptera: Figitidae). En el campo se observaron daños ocasionados ...
The demand of guava in ColombiaLa demanda de guayaba en ColombiaA demanda de goiaba na Colômbia
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2016)
In Colombia, no systematic work have been carried out to determine the demand for fruits beyond descriptive analysis of per capita consumption according to different individual socioeconomic characteristics and much less for a specific product such as guava, Psidium guajava L. (Myrtaceae). This paper estimates the relationship between guava prices and the demand of guava in Colombia. We found that guava consumption is ...
Estimación del contenido de carotenoides en la pulpa de frutos de gulupa (Passiflora edulis Sims) conforme a la variación del color en la cáscaraEstimating fruit pulp carotenoid content from shell color in gulupa (Passiflora edulis Sims)
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2013)
La gulupa (Passiflora edulis Sims) es un fruto aceptado en mercados europeos; pero, su corta vida en poscosechalimita la comercializacion. Por lo tanto, es necesario, caracterizar algunos atributos de la maduracion, para que el fruto mantenga las mejores condiciones de calidad. La investigacion tuvo como objetivo estimar, a partir de los cambios de color del fruto y de su edad, la evolución de los carotenoides, mediante ...
Comparación de las características de calidad de fruta en genotipos de papaya (Carica papaya L.) provenientes de Shushufindi y La Joya de los Sachas, Ecuador
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2021)
En el norte de la Amazonía ecuatoriana se encuentran genotipos de papaya que, si bien tienen características aceptables de producción y calidad de fruta, son heterogéneos. El objetivo de esta investigación fue evaluar estos genotipos para la selección de individuos con base en las características de calidad de fruta. El estudio se desarrolló en la Estación Experimental Central de la Amazonía del Instituto Nacional de ...
Comparative leaf anatomy of lulo (Solanum quitoense Lam.) materials with and without thornsAnatomía foliar comparativa de materiales de lulo (Solanum quitoense Lam.) con y sin espinas
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2008)
A study was carried out to describe the lulo (Solanum quitoense Lam.) leaf anatomy of materials with thorns (CE, accession ‘NM’) and thorn less (SE, accession ’SV80’) under full sun exposure, in the upper, middle and lower plant strata, during the vegetative and productive phases. No significant morphological differences between the leaf structures of both genotypes were found during the ontogenic studied periods. Both ...
Molecular diagnosis of Phytophthora cinnamomi associated with root rot in avocado producing areas of EcuadorDiagnóstico molecular de Phytophthora cinnamomi asociado a la pudrición radicular en zonas productoras de aguacate en EcuadorDiagnóstico molecular de Phytophthora cinnamomi associado com a podridão radicular em áreas produtoras de abacate no Equador
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2017)
One of the most damaging diseases in cultivation of avocado (Persea americana Mill.) is root rot associated with Phytophthora cinnamomi Rands. This disease causes progressive wilt and even death of the tree. The objective of this study was to identify the presence of P. cinnamomi in two productive areas of avocado in Ecuador using the molecular technique PCR-RFLP. Tree root samples were obtained with root rot symptoms ...
Cytogenetics of Physalis peruviana L. and Physalis floridana Rydb. genotypes with differential response to Fusarium oxysporumCitogenética de genotipos de uchuva, Physalis peruviana L., y Physalis floridana Rydb., con respuesta diferencial a Fusarium oxysporum
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2015)
Vascular wilt caused by the fungus Fusarium oxysporum is considered the main constraint of cape gooseberry, Physalis peruviana, production in Colombia. P. peruviana and P. floridana genotypes with differential resistance responses against F. oxysporum have been identified previously. In the present study, the genotypes were evaluated in order to complement the knowledge of cytogenetics diversity in Physalis and to ...
