Para el efecto se utilizó un diseño de bloques completos al azar con un arreglo de tratamientos en un diseño compuesto central ortogonal. Para evaluar la relación de los niveles de fertilización y la severidad de la enfermedad, se hizo una inoculación artificial en tallos de mora de Castilla con espinas, mediante discos de micelio de 0.5 cm a una concentración de 9.53 x 104 conidias. Las observaciones consistieron en: severidad de la enfermedad (S), periodo de incubación (PI) y tasa de desarrollo (r). Los análisis de datos se hicieron por el método de conglomerados sobre la variable severidad, un análisis de correlación de Pearson entre variables, así como una regresión para estimar el efecto de los nutrientes aplicados sobre la severidad de la cepa-52 de C. gloeosporioides. Los tratamientos se concentraron en cuatro grupos con los rangos (entre paréntesis) S (15.9% y 91.8%), PI (9 y 15.3) y r (0.0254 y 0.0468). Se observó correlación positiva y significativa entre S y r (P < 0.001) y negativa entre PI con S y r (P < 0.001).

The aim of this work was the experimental optimization of the freeze-drying process (LIO) of the Russian tarragon leaves (Artemisia drancunculus L.) to preserve, in the best possible way, its properties. We used a tray freeze dryer, where the material was frozen from 25 °C to -40 °C, at a speed of 0.22 °C/min. The optimization was carried out using response surface methodology with an optimal design, as a function of independent variable plate heating rates (0.03 – 0.06 °C/min) from -40 °C to 35 °C, holding the temperature of the plate at 35ºC for one hour. The dependent variables were moisture content, water activity (aw), antioxidant activity, color and drying time. The product dried in the optimum condition was compared with another drying by forced convection (SC). The freeze-drying time process presented statistically significant differences with the plate heating speed (VCP). LIO Optimal condition was obtained at a VCP of 0.06 °C/min for 20.8 hours. The dried products with both methods showing showed statistically significant differences in aw, moisture, DPPH, and color, but not in total phenol content.

The aim of this research was to assess the main propagation methods of this species and to evaluate the survival of the seedlings in different environments. Two experiments were installed in the headquarters house of IBAMA situated in the Araripe National Forest (FLONA), Crato, State of Ceará, Brazil. The potential of seedling production and stem and root cuttings were evaluated, as well as seedlings adaptation to both environments (experimental area and natural habitat). For seedlings production, the experimental design was completely randomized in a 4 x 2 factorial scheme (four sowing seasons and two distinct environments), with three replications and twenty-five seeds per replicate, with a total of 600 seeds. For evaluation of substrate effect, cutting type and environment, treatments were distributed in a completely randomized design, in a 2 x 4 factorial scheme, which corresponded to two types of cuttings and four substrates in two replications with 72 cuttings per replicate. The number of live cuttings with callus of rooted cuttings, root fresh mass and root dry mass, leaf persistence, height and survival of the seedlings were also evaluated. Seedlings development was significantly greater in the experimental area indicating that V. arborea is a plant that can be rationally exploited. It is recommended that for the propagation of the species, other types of propagules should be tested since there was no success with the use of root cuttings.","PeriodicalId":135011,"journal":{"name":"Acta Agronómica","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124160074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hay muchos estudios que han demostrado que los begomovirus evolucionan por mecanismos de intercambio genético, que ocurren en hospedadores alternativos como las malezas. Las malezas están ampliamente distribuidas en todo el mundo y tienen una alta adaptabilidad ambiental. El objetivo de este trabajo fue identificar nuevos hospederos alternos de begomovirus en malezas asociadas con cultivos de aji que crecen en el Valle del Cauca. Malezas con y sin síntomas virales alrededor de cultivos de aji ubicados en los municipios de Zarzal, Vijes, Toro, Unión, Roldanillo y Guacarí fueron colectadas; Se realizó una identificación taxonómica en el Herbario de la Universidad Nacional de Colombia, Josep Cuatrecasas Arumí.La detección de begomovirus se realizó mediante PCR utilizando cebadores universales que amplifican 400 pb, correspondientes a un fragmento del gen AR1 (CP) del componente A. Se recolectaron 179 malezas y en 13 de ellas (Sida acuta, Malvastrum sp, Rivina humilis, Acalypha sp, Parthenium hysterophorus, Euphorbia hirta, Rhynchosia minima) se detectó la presencia de begomovirus. Para malezas como Sida acuta y Acalypha sp, este es el primer informe como hospedero alterno de begomovirus en Colombia, América Latina y el Caribe. Este resultado permite conocer nuevas familias como hospederas de begomovirus y también para confirmar la presencia de begomovirus en otras malezas donde se detectaron previamente en el Valle del Cauca. Existe una necesidad apremiante de obtener información adicional relacionada con la diversidad y la distribución de malezas como hospederos de begomovirus, con el fin de descubrir no solo el control del virus, sino también evitar la propagación del begomovirus de las malezas a los cultivos con interés económico.","PeriodicalId":135011,"journal":{"name":"Acta Agronómica","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114612720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A five-fold assay in a randomized design was carried out using standard inoculum of fungal conidia, which were subjected to an array of contact times and AEW concentrations, using a controlled agitation (120 r.p.m) at 23°C. The conidia treated with AEW were grown on potato dextrose agar and their germination was evaluated. Mycelial growth of the treated samples was measured and compared against conidia control samples treated with distilled water instead of AEW. Botrytis cinerea and Rhizopus stolonifer were the most commonly isolated species at 54.25% and 28.72%, respectively. AEW inhibited conidia germination after 7 minutes of exposure. The AEW concentration required to inhibit conidia germination was 10 ppm and 50 ppm for R. stolonifer and B. cinerea respectively, a variance possibly due to the constitution of their cellular walls. A short exposure of AEW is able to inhibit post-harvest fungi growth, and is thus recommended as an efficient, economical, and environmentally sustainable sanitation agent, with the ability of extending the strawberry post-harvest consumption period.","PeriodicalId":135011,"journal":{"name":"Acta Agronómica","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
