Nutrient removal with harvest of biomass of Eucalyptus dunnii maiden grown in short rotation coppice for bioenergy.
The continue increase in world population, coupled with the environmental problems caused by the use of fossil fuels, has led to the search of new sources of renewable energy. Among these, is the use of eucalyptus biomass grown on short rotation coppice for energy production, in which all the components of the tree are harvested. Based on this, some questions arise:Can we call renewable energy the one in which all the components of the tree are removed from the soil every four year? What are the consequences from the nutrient cycling point of view?
Differences in growth between Corriedale sheep divergent lines for resistance to nematodes.
The association between genetic resistance of lambs to gastrointestinal parasites (GIP) with dry matter intake (DMI) average daily gain (ADG) and residual feed intake (RFI) was studied. Sixty-four Corriedale lambs (357±14 days old), from divergent lines for resistance to GIP (27 resistant-R and 37 susceptible-S) developed by the Uruguayan Wool Secretariat were used. The animals were allotted to one of five outdoor pens, they were stratified by sex, body weight, and sire.
Evaluation of udder morphology and milk production in prolific and meat ewes.
Currently in Uruguay, several experiments of crossbreeding and synthetic breeds are being developed with the inclusion of East Friesian (EF), Finnsheep (F) and Texel (T) meat breeds. The milk production and udder morphology of 57 ewes (8 F, 24 EF and 25 T breeds) from three flocks were evaluated. A total of 161 records (24 F, 68 EF and 69 T breeds) were collected in three test-day controls with average days in milk (DIM) 21, 40 and 60. The ewes were randomly assigned to four experimental groups and separated from the lambs during 4 hours in a good pasture.
Caracterización molecular y biológica de aislamientos de campo de CTV de Uruguay y su potencial en la protección cruzada.
Citrus tristeza virus (CTV) es el agente causal de la tristeza, una de las enfermedades virales más importantes de los cítricos. El mecanismo de protección cruzada sería una alternativa interesante de manejo en nuestra situación pero para implementarlo es necesario conocer las características de los aislados locales e identificar aquellos que se adecuen a esa estrategia. El objetivo de este trabajo ha sido determinar la severidad de aislamientos de campo de CTV mediante bio-ensayos en plantas de referencia y caracterizarlos mediante métodos moleculares.
Avances en el Programa Nacional de Saneamiento y Certificación de Cítricos de Uruguay. [trabajo en conferencia.].
En 2010, luego de un proceso liderado por la Comisión Honoraria del Plan Citrícola (CHNPC), INIA, INASE, DGSA y el propio Ministerio de Ganadería, Agricultura y Pesca (MGAP), se firmó un convenio interinstitucional para desarrollar un Programa Nacional de Saneamiento y Certificación de Cítricos (PNSCC). En el presente trabajo se presentan los avances y logros alcanzados para poner a disposición del Sector citrícola nacional, yemas de variedades y semillas de portainjertos certificadas libres de virus.
NMR metabolomics as a prediction tool for consumers acceptance of mandarins. (SI-O-7) [oral presentation].
These results could be applied in breeding programs to select new cultivars based in chemical data that correlates with consumers? acceptance without bias or subjective opinions, speeding up the development of new Citrus varieties.
Molecular characterization by microsatellites of cultivars from the cuban citrus protected germplasm bank. (SI-P-3). [poster presentation].
The genetic certification of the species and cultivars present in the Citrus Protected Germplasm Bank (BGP) is a task of the first order to continue improving the Production System of Certified Citrus Material of Cuba.
