2. Variabilidad de Baja Frecuencia de la Persistencia de la Temperatura en el Sudeste de Sudamérica
Abstract Eight reference stations in south-eastern South America are analysed to derive the auto-covariance and auto-correlations of maximum and minimum temperature. Through the analysis are observed oscillations of periods between 18 and 25 years in the series studied. These periodicities show changes over time, especially in the 1950-1970 period. The excep

3. VARIABILIDAD GENÉTICA DE PARENTALES Y POBLACIONES F1 INTER E INTRAESPECÍFICAS DE Physalis peruviana L. Y P. floridana Rydb.
ABSTRACTCape gooseberry, Physalis peruviana, is an Andean fruit of great importance for export markets; its main limitation for production in Colombia is the vascular wilt caused by Fusarium oxysporum. The present study proposed the generation of F1 populations between contrasting pathogen response parents and their evaluation at molecular level to support

4. Caracterizacion y analisis de la variabilidad genética de la granadilla (Passiflora ligularis juss.) en Colombia empleando marcadores microsatélites
Sweet passion fruit is the second economically important species of the genus Passiflora and Colombia is the largest producer in the world with 53,000 t/year. There are however, few studies on intraspecific diversity within the species that establish genetic relationships between individuals. The objective of this research was to explore the genetic variabil

5. Caracterización y variabilidad genética de Colletotrichum gloeosporioides sensu lato en plantaciones de palma aceitera (Elaeis guineensis Jacq.) en Venezuela
Characterization was performed on the causal agent of anthracnose affecting leaves, rachis and fruits of oil palms in the southern region of Maracaibo Lake (Venezuela). Morphological tests included colony growth rate, diameter, color and type of mycelium, as well as the shape and size of conidia. Molecular characterization included specific PCR tests, ITS rD

7. Influencia das variáveis de processo na variabilidade do número kappa em um sistema de cozimento SuperBatch-K / Influencia de los parámetros de proceso en la variabilidad del número kappa en un sistema de cocción SuperBatch-K
O processo de cozimento SuperBatch-K foi analisado utilizando-se dados industriais de um período de 5 meses. Os dados referentes à madeira e licores de processo foram avaliados. O comportamento do sistema durante este período foi analisado através das variáveis chaves de processo e as características da polpa produzida. Tanto a madeira quanto as variá

8. Variables físicas que explican la variabilidad de suelo aluvial y su comportamiento espacial
The objective of this work was to use the principal component and semivariance analyses to select physical variables that could explain the variability of an alluvial soil, in order to establish the spatial behavior of the chosen variables so that the location of experimental plots could be technically defined to study the abrasiveness effect on the wearing

9. Variabilidad de Puccinia sorghi en la zona maicera núcleo Argentina
Common rust caused by Puccinia sorghi is one of the endemic diseases of corn in Argentina. It appears every year with different levels of severity depending on the genotype of the host, the biotypes of the pathogen, and the environmental conditions. Estimates of grain weight losses ranged from about 3 to 8% for 10% of the total leaf area affected. P. sorghi
