Associations between clones and morphologic abnormalities in red type garlic ( Allium sativum L.)

Con el objeto de detectar la influencia del genotipo en la presencia de anormalidades morfológicas, se tomó una muestra de 200 bulbillos de cada uno de los 7 clones de ajo colorado, incluidos en un ensayo experimental en bloques completamente aleatorizados con 4 repeticiones, en un solo ambiente de expresión. En cada clon se computaron las proporciones de bulbos normales, pera, cebollón y doble. En los bulbos normales se midió la distribución de calibres. Se compararon las proporciones de anormalidades entre los clones. Un clon se diferenció (p < 0,05) de los restantes por no poseer malformaciones y presentar un calibre promedio bajo. Utilizando en conjunto la información obtenida, se realizó un análisis de componentes principales y de conglomerado. Se utilizó la distancia euclidiana promedio y el método de ligamiento promedio. Los dos primeros ejes del análisis de componentes principales representaron el 74% de la variación de los datos. La información obtenida permitió reunir 3 grupos de clones por su asociación a calibres y anormalidades morfológicas. El primer grupo formado por un clon sin anormalidades y con mayor proporción de calibre 4 y 5; el segundo, de cuatro clones con presencia de ajo cebollón y el tercero, de dos clones asociados a los bulbos pera, dobles y de calibres 6. Se demostró la influencia del genotipo en la frecuencia de anormalidades morfológicas.With the object to detect the influence of the genotype in the presence of morphologic abnormalities, a sample of 200 took cloves of each of 7 clones of red garlic was taken included in an experimental essay in blocks completely randomized with 4 repetitions, in only one environment of expression. In every clone there were calculated the proportions of normal bulbs, pear-like bulbs, onion-like bulbs and double bulbs cloves. In the normal bulbs the distribution of calibres measured up. The proportions of abnormalities were compared between the clones. A clone differed (p < 0.05) of the remaining ones for not possessing malformations and a low average calibre presented. Using the obtained information as a whole, an analysis of principal components and of the clustering was made. The euclidea average distance and the method of average linkage was used. The first two axes of the analysis of the principal components represented 74% of the variation of the data. The obtained information allowed to assemble 3 groups of clones because of its association to calibres and morphologic abnormalities. The first group formed by a clone without abnormalities and with major proportion of calibre 4 and 5; the second one, formed by four clones with the presence of onion-like bulbs and the third one, of two clones associated with the pear-like bulbs, doubles bulbs cloves and of calibres 6. The influence of the genotype was demonstrated in the frequency of morphologic abnormalities.Fil: Silvestri, Víctor. Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias.

Evaluation method in field of the blue mold resistance in garlic accessions

Con el objeto de ajustar un método de evaluación a campo para facilitar la selección de clones de ajo (Allium sativum L.) con resistencia a Penicillium allii, se realizó un ensayo replicado en el cual se midió la respuesta de tres clones experimentales a la infección, en dos épocas de plantación. Los tratamientos incluyeron combinaciones de presencia o ausencia de: a) desinfección de la "semilla", b) heridas artificiales en los bulbillos, c) inoculación artificial. Los bulbillos con la hoja envolvente se desinfectaron con una solución diluida de hipoclorito de sodio. La inoculación se realizó mediante la inmersión en una solución de 106 esporas•ml-1. Las heridas se realizaron con una lanceta (blood lancet). Los bulbillos se incubaron en cámara húmeda durante 24 horas a 20 °C, antes de plantación. Las variables respuestas computadas fueron las siguientes: número de plantas muertas, y vivas con síntomas y sin síntomas, a los 152 días de plantación en la primera época y 118 días en la segunda; número de bulbos por calibres y rendimiento a cosecha. La información obtenida se analizó a través de correspondencia simple, diferencia de proporciones y análisis paramétricos. Se detectaron mayores diferencias entre los tratamientos en la tasa de sobrevivencia y en la proporción de calibres comerciales en la época tardía. No se observaron diferencias (p < 0,05) del rendimiento en la plantación temprana. La herida fue determinante en el ingreso del patógeno. Los tratamientos quedaron limitados a un testigo: desinfectado, no inoculado y sin herida, y a un tratamiento: desinfectado, con inoculación y herida. Con respecto a la época, resultó conveniente la evaluación en plantaciones tardías porque se expresan mejor las diferencias entre los tratamientos.In order to establish a method of selection in the field of clones of garlic (Allium sativum L.) resistance to Penicillium allii, a test was conducted to measure the response of three clones to the infection, at two times of plantation that corresponded to cycles of 152 (early plantation) and 118 days (late plantation). The treatments included combinations of presence or absence of: a) disinfection of the "seed", b) artificial wounds in the cloves, c) artificial inoculation. The cloves and their surrounding leaf were disinfected with diluted sodium hypochlorite. The inoculation consisted of dipping the cloves in a solution of 106 spores•ml-1. The wounds were produced by a blood lancet. The cloves were incubated in humid chamber for 24 hours at 20 °C, before plantation. The variables measured were number of plants dead, alive with symptoms and alive without symptoms, 152 and 118 days after plantation and bulb diameter and yield. Results were analyzed statistically using non parametric and parametric tests. Significant differences between treatments were found 118 days after plantation regarding the rate of survival and the proportion of commercial calibers. No differences in yield (p < 0.05) were detected in the early plantation. Wounding was determinant for the entrance of the pathogen. It is concluded that treatments can be limited to a control (disinfection, not inoculated and not wounded) and a treatment with disinfection, inoculation and wounding. Late plantations are more sensible to the detection of differences between treatments.Fil: López Frasca, Adriana. Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias.

Management of anticoagulation with vitamin K antagonists in a tertiary hospital outpatient clinic

Introduction: atrial fibrillation (AF) is one of the main risk factors for stroke. Vitamin K antagonists (VKA) reduce this risk, and the effectiveness of this treatment is directly related to time in therapeutic range (TTR). This study aimed to report the TTR in patients with non-valvular AF at an anticoagulation outpatient clinic; and to describe the profile of this population of patients in terms of risk of stroke, as well as the occurrence of adverse events during the follow-up. Methods: Retrospective cohort study involving patients of the anticoagulation outpatient clinic of the Department of Internal Medicine at Hospital de Clínicas de Porto Alegre. We evaluated outpatient visits, hospital admissions, and emergency visits from January to December 2011. TTR was calculated using the Rosendaal method. Results: Sixty-three patients were investigated. Their mean age was 74.3±10.9 years. The CHADS2 score was ≥ 4 in 44.5% of the patients; 63.5% of them had a CHA2DS2-VASc score ≥ 5. The TTR was 64.8%. During follow-up, the incidence of overall bleeding was 31.7%, with major and minor bleeding rates of 4.8% and 34.9%, respectively. There were no other complications related to AF or anticoagulation. Conclusion: The patients achieved a TTR of 64.8% during follow-up, which is deemed appropriate and in agreement with the literature. Patients had high risk for stroke, and the incidence of minor bleeding was higher than the rate found in the literature, whereas the incidence of major bleeding was similar to the one found in previous studies

Bulk soybean grain mass temperature in warehouses with isolated vents and vent-exhaust combined systems

ABSTRACT: This study aimed to compare the temperatures in the mass of bulk soybeans ( Glycine max ) in warehouses with isolated vents and vent-combined exhaustion. A completely randomized design was used, with two treatments and ten repetitions. Treatments consisted of warehouse with curved vents and warehouse with curved + static exhaust vents. Each repetition contained the average of all readings in three days in all cables of the warehouse part under study, totaling 10 repetitions per month. The variable analyzed was the temperature in the grain mass in the lower, middle and upper parts of the warehouse from January to May 2012. The environment temperature and humidity were also registered. Static hoods, along with curved vents on the roof of the warehouse showed a tendency to reduce the temperature of the soybean mass with decrease in environmental temperature and increase in relative environmental humidity
