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 ...
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, 2012)
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 ...
Development analysis of Mortiño (Vaccinium meridionale Swart.) plants derived from clonal and sexual propagationAnálisis del desarrollo de plantas de mortiño (Vaccinium meridionale Swart.) bajo dos sistemas de propagación: clonal y sexual
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2015)
A research was carried out at Corpoica´s La Selva,Experiment Station located at Rionegro, Antioquia,Colombia, at 2.120 masl in the ecological zone Low Mountain Rain Forest. The objective was to characterize growth and development of andean blueberry Vaccinium meridionale Sw., plants, obtained by seed and clonal propagation, from a wild population of the species. Four plants of each type were transplanted to rizhotrons, ...
Degradation of vitamin C in a product made from mango (Mangifera indica L.) and whey proteinDegradación de la vitamina C en un producto de mango (Mangifera indica L.) y lactosueroDegradação da vitamina C em um produto de manga (Mangifera indica L.) e lactisoro
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2017)
This study aimed to determine the kinetics of vitamin C degradation in a product made from mango pulp (Mangifera indica L.) and whey protein powder, in order to determine the effect of temperature on its conservation and further evaluate the behavior of the L*, a*, b* and the total color difference (ΔE) in the powder product. Vitamin C was determined by the aoac 967.21/90 method using 2,6-dichlorophenol indophenol, and ...
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, 2014)
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 ...
Determination of safe storage under controlled for rootstock seed of ‘Tahiti’ limesDeterminación de condiciones controladas de almacenamiento seguro para semillas de portainjertos de lima ácida ‘Tahití’
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2012)
One of the disadvantages in agricultural production is the adequate and timely supply of seeds. The absence of controlled storage methods of citrus seeds in nurseries is the main limiting factor for the production of planting material, because 40% of this material is lost through poor physiological quality of the seeds. The objective of this study was to determine the best conditions for storing seeds of CPB Citrumelo ...

(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2013)
This article establishes the financial viability for the production and export of gulupa (Passiflora edulis Sims) to the Spanish market, including environmental, technical and economic elements. 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 ...
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 ...
