RESUMEN. El portainjerto en frutales juega un papel importante en el control de vigor de la planta, en la precocidad de producción y en la adaptación a ciertas condiciones de suelo, entre otros. Desde 1999, el Programa de Investigación en Producción Frutícola de INIA en Uruguay, está evaluando diversas combinaciones portainjerto- variedad de peral, con el objetivo de seleccionar aquella que ofrezca mayor potencial agronómico, permitiendo mayores producciones de calidad comercial, en el ambiente templado-húmedo de la región.

ABSTRACT. Information about olive-tree irrigation in sub-humid climates, as in Uruguay, is scarce. Water consumption of young olive trees, Arbequina variety, was measured for two years with six drainage lysimeters, protected from rain by an automatic rain-out shelter. Irrigation water volume and drainage of each lysimeter were measured daily and soil moisture was registered twice a week with neutron probe at four depths. Evapotranspiration (ETc) was calculated by volume balance.

ABSTRACT: The Pear Psyllid, Cacopsylla bidens (?ulc, 1907), is here reported from the Department of Canelones, the major region of pear production in Uruguay. Previous records of C. pyricola (Foerster, 1848) from Uruguay are misidentifications of C. bidens. Information is provided on the taxonomy and biology of this species. ©2017 Check List and Authors
