ABSTRACT: Flooding is an important method for weedy rice control. The reduction of the flooding effect ongermination and initial growth of weedy rice has been observed, which compromise the efficiency of flooded rice systems. The objectives of this study were to establish a methodology for the selection of weed rice populations with flooding tolerance, to evaluate the expression of genes associated to flooding in cultivated rice, and to investigate the effect of temperature and soil depth on tolerance to flooding in weedy rice.

Seed shattering in weedy rice is not similarly regulated as in cultivated rice.

ABSTRACT: Although seed shattering is one of the main causes of weedy rice persistence it still is poorly understood. The aim of this study was to identify the main genes related with the occurrence of seed shattering in weedy rice. Gene expression and DNA sequencing of the coding and promoter region and a whole genome sequencing were performed in weedy and cultivated rice with contrasting seed shattering. The main genes associated with the seed shattering in cultivated rice Sh4, qSH1 and SHAT1 were not important in weedy rice.

The objective of this study was to investigate the feeding behaviour impact due to walking in dairy cowswalking 5 km between the milking parlour and the pasture plot in a grazing system, separating the effect of walking itself from the fasting period associated to walking.

El objetivo de este trabajo fue estudiar el efecto de diferentes estrategias nutricionales sobre la calidad de la carne y composición de ácidos grasos (AG) en vacas de descarte. El experimento combinó diferentes niveles de asignación de forraje (AF) pastoreando un cultivo de avena y raigrás y el uso de afrechillo de arroz (AA) durante 130 días.

The objective of this work was to study the effect of different nutritional strategies on fatty acid composition in cull cows in Uruguay. The experiment combined different levels of forage allowance (FA) grazing a winter crop (oat and ryegrass) and the use of a supplement (rice bran; RB) for 112 days.
