ABSTRACT.- Background: Eucalyptus globulus Labill. is a species of great interest to the pulp industry. However, it has a low rooting capacity, which makes it difficult to clone on a commercial scale. In micropropagation, the supply of cytokinins is necessary to stimulate proliferation, but the type and concentration of cytokinins can negatively affect adventitious rooting. This study evaluated the effect of metatopoline (mT) and benzyladenine (BA) on in vitro multiplication, elongation, and rooting of E. globulus clones.

Existen varios tipos de injertos. Injerto de parche. Es el más usado en los viveros. -- Injerto de cuña. Se utiliza para cambio de copa en plantas adultas.

El objetivo de este trabajo es presentar una experiencia de extensión universitaria, llevada a cabo en equipo por un grupo de docentes de la Universidad de la República, estudiantes de la Escuela de Artes y Artesanías (CETP-UTU) y las comunidades de una escuela del balneario Solís y una escuela rural de Solís Grande, ambas en Maldonado, con el fin de compartir y motivar el trabajo en torno al agua, los ecosistemas de los que forma parte y sus usos humanos.

ABSTRACT.- The Enteric Fermentation Flagship project, funded by the Global Research Alliance, was initiated in 2018 to investigate rumen microbiomes to predict methane emissions in bovine species. A major objective of this project was to implement a low-cost, high-throughput method for profiling the rumen microbiome in bovine species across different production stages and systems used around the globe.

ABSTRACT.- In a previous study, we reported the in vitro potential probiotic and gamma-aminobutyric acid (GABA) production, of several strains from a collection of Lactiplantibacillus (Lpb) strains within the community of natural whey starters from the artisanal cheese industry. GABA is a non-protein amino acid widely distributed in nature and produced in animals, plants, and microorganisms. However, the best known role of GABA is its function as the major inhibitory neurotransmitter of the central nervous system.

ABSTRACT.- The intensification of droughts due to climate change is a global concern, and many plant species face increasing water deficits. Understanding the role of phenotypic plasticity in plant adaptation to these changing conditions is crucial. This research focuses on Bromopsis erecta, a dominant perennial grass in European and Mediterranean grasslands, to predict its potential adaptation to climate change.

ABSTRACT.- The present article describes the development of an improved Pinus taeda clonal seed orchard adapted to the edaphoclimatic conditions of Uruguay. Initially, 2068 hectares distributed in nine companies were prospected, and 124 plus trees were identified based on growth, straightness, and health traits. These trees were clonally propagated via grafting to establish a clonal seed orchard. For the genetic evaluation of the orchard, two progeny tests were carried out in the Rivera and Paysandú municipalities.

ABSTRACT.- In Uruguay, methane (CH4) emitted from livestock sector contributes with 46.1 % of the total national emissions, where more than 70% of the beef finishing cattle are fed with forage varying the quantity or quality offered. As CH4 emissions are affected by quantity and quality of food intake, there is a need to quantify these changes. This work aimed to quantify the effect of different NDF content of forage diets on CH4 emissions from beef steers during the finishing stage.

Genetic improvement of resistance to gastrointestinal nematodes (GIN) in sheep is a well-known strategy to reduce the negative consequences of GIN, whose control is limitecl by resistance to anthehnintics, on sheep health and performance.
