Mexico and the food self-sufficiency (six-year period 2006 -2012)México y la autosuficiencia alimentaria (sexenio 2006 -2012)
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2014)
Today, Mexico challenges a globalization trend where richer countries export basic products to developing countries, generating a food crisis that negatively affect the medium-small producers. For this reason, it is important to study the behavior of the food market (exports and imports), since the current Mexican development model does not achieve that food security be a national policy guaranteeing the provision of ...
Chemical composition and distribution of dry matter in genotypes of banana and plantain fruitsComposición química y distribución de materia seca del fruto en genotipos de plátano y bananoComposição química e distribuição de matéria seca do fruto em genótipos de banana cumprida e banana
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2016)
The distribution of dry matter in the bunch and chemical attributes of the fruit were evaluated in 12 cultivars of plantain and banana from the Musaceae Colombian Collection (CCM) and the similarities among the clusters were determined by a statistical analysis of main components and conglomerates The variables percentages of matter in pulp, percentages of matter in nuts, percentages of fresh pulp, starch content, K, ...
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, ...
Genetic variability study of field Leptospira spp. isolates in beef and double purpose bovine production systemsEstudio de variabilidad genética en aislamientos de Leptospira spp., en sistemas bovinos de carne y doble propósito
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2016)
A partir de riñón y orina de bovinos, se aislaron en campo serovares de Leptospira spp., en los departamentos de Cundinamarca y Meta, Colombia. Los aislamientos fueron clasificados mediante análisis filogenético y ribotipificación, utilizando como marcador el gen 16S ADNr. El análisis filogenético permitió clasificar los aislamientos en dos de las tres genomoespecies reconocidas: patógeno e intermedio, siendo este ...
Effect of irrigation and fertilization on crop yield and fruit quality of the Tahiti lime Citrus latifolia Tanaka (Rutaceae)Efecto del riego y la fertilización sobre el rendimiento y la calidad de la fruta de lima ácida Tahití Citrus latifolia Tanaka (Rutaceae)
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2015)
In a seven years old citrus grove of Tahiti lime Citrus latifolia Tanaka (Rutaceae) located in El Espinal, Tolima,Colombia, which has a predominantly negative water balance throughout the year, we evaluated the effect of irrigation and fertilization on yield and fruit quality in 2009 and 2011. Trees were subjected to three levels of water based on the evapotranspiration reference (ETo):L1=100 %, L2=70 % and L3=50 %. ...
Annual trends of the Coffee Degree Day and Coffee Borer Degree Day in the equatorial Andean region in ColombiaTendencia anual de los grados día cafeto y los grados día broca en la región andina ecuatorial de Colombia
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2015)
It is expected that climate change modifies the current spatial pattern of coffee cultivation in mountainous slopes of Colombia. However, the approaches used to reach these results are based on the use of (global and regional) climate models and species distribution models that largely supported in the niche concept. In order to assess the certainty of the results obtained with these models, a methodology in which data ...
Voltammetric Quantification of Paraquat and Glyphosate in Surface WatersDeterminación voltamétrica de paraquat y glifosato en aguas superficialesDeterminação voltamétrica de paraquato e glifosato em águas superficiais
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2016)
The indiscriminate use of pesticides on crops has a negative environmental impact that affects organisms, soil and water resources, essential for life. Therefore, it is necessary to evaluate the residual effect of these substances in water sources. A simple, affordable and accessible electrochemical method for Paraquat and Glyphosate quantification in water was developed. The study was conducted using as supporting ...
Genetic diversity of the INPA germoplasm bank of camu-camu (Myrciaria dubia [H.B.K.] McVaugh) using microsatellites markers (EST-SSR)Diversidade genética em acessos do banco de germoplasma de camu-camu (Myrciaria dúbia [H.B.K.] McVaugh) do INPA usando marcadores microssatélites (EST-SSR).
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2011)
The knowledge of genetic diversity in Amazonian species is of great importance for domestication and breeding purposes. A great difficulty with non-domesticated species such as “camu-camu” is the lack of information about their genetic variability. Due to the economic potential of camu-camu, a fruit with a high level of vitamin C production, the aim of this study was to estimate the genetic diversity using the molecular ...
Caracterización de maíz procedente del departamento del Magdalena, Colombia
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2016)
Se presenta el estudio fenotípico de 13 variedades de maíz donadas por la Universidad Nacional de Colombia sede Palmira, analizando la varianza, frecuencias, componentes principales, discriminantes y de agrupamiento. Mostrando diferencias significativas entre introducciones para la mayoría de variables, lo que se considera un indicador de diversidad.
Identificación de tecnologías y métodos para la detección temprana del Huanglongbing (HLB) a través de cienciometría en artículos científicos y patentes: una revision
(Corporación colombiana de investigación agropecuaria - AGROSAVIA, 2020)
El objetivo planteado para esta revisión de literatura científica y de patentes consiste en identificar las tendencias científicas y tecnológicas en la detección del Huanglongbing (hlb) o enverdecimiento de los cítricos, así como las principales acciones que se están adelantando para mitigar su impacto en la citricultura mundial. La detección rápida y oportuna de esta enfermedad es clave para los productores, debido a ...
