Tree Nitrogen Status and Leaf Canopy Position Influence Postharvest Nitrogen Accumulation and Efflux from Pear Leaves
(American Society for Horticultural Science, 1990-11)`Cornice' pear trees (Pyrus communis L.) were fertilized with ammonium nitrate depleted in “N in Spring 1987 and 1988. In Aug., Oct., and Nov. 1988, midleaves on current season shoots were sampled at three positions from ... -
Management of Nitrogen and Calcium in Pear Trees for Enhancement of Fruit Resistance to Postharvest Decay
(American Society for Horticultural Science, 1992-07)Management of pear (Pyrus communis L.) trees for low N and high Ca content in the fruit reduced the severity of postharvest fungal decay. Application of N fertilizer 3 weeks before harvest supplied N for tree reserves and ... -
Effect of Postharvest Soil and Foliar Application of Boron Fertilizer on the Partitioning of Boron in Apple Trees
(American Society for Horticultural Science, 2005-12)This study was carried out on mature `Delicious' apple trees (Malus domestica Borkh.) on EM 9 rootstock. Labeled B (99.63 Atom % 10B) was applied as boric acid. Treatments were postharvest foliar B at 375 mg·L–1, postharvest ... -
Nuevos registros de Habrobracon hebetor (Hymenoptera: Braconidae) en la Argentina
(Sociedad Entomológica Argentina, 2009)Se proveen nuevos registros de Habrobracon hebetor (Say) de Choele Choel, Río Negro, y de la Ciudad Autónoma de Buenos Aires, Argentina. Parte de los ejemplares analizados fueron criados a partir de larvas de Plodia ... -
Physiological response of "Larry Ann" plums to cold storage and 1-MCP treatment
(Elsevier, 2009-01)The aim of this work was to study the specific effects of low temperature and 1-MCP treatment on ethylene metabolism and oxidative behaviour in plums (Prunus × salicina cv. Larry Ann). Control fruit were stored at 20 °C ... -
Research knowledge and needs for orchard floor management in organic tree fruit systems
(Taylor and Francis, 2009-09-28)While pest management and tree horticulture dominate the research agenda for temperate tree fruits, organic production requires more attention to weed control and nutrient management because of the limited options growers ... -
Evaluation of low-drift nozzles in agrochemical applications in orchards
(Instituto de Investigaciones Agropecuarias (INIA), Chile, 2010)Fruit production demands several phytosanitary treatments per year. The efficiency of these treatments is affected by product loss because of drift, a situation that is aggravated by frequent high winds and the presence ... -
Effect of pressure on the quality of pesticide application in orchards
(Instituto de Investigaciones Agropecuarias (INIA), Chile, 2010)Only part of the active ingredient used in agrochemical applications in orchards is retained on the trees. The product that is not retained is lost as sedimentation in the soil and as drift, the latter being a major source ... -
Comparison of lures loaded with codlemone and pear ester for capturing codling moths,Cydia pomonella, in apple and pear orchards using mating disruption
(Oxford Academic Press, 2010-01)Studies were conducted in apple, Malus domestica Borkhausen and pear, Pyrus communis L. (Rosales: Rosaceae), orchards to evaluate the attractiveness of grey halobutyl septa loaded with 1 (L2) and 10 (Mega) mg of codlemone, ... -
Cross transferability of SSRs to five species of Araucariaceae: a useful tool for population genetic studies in Araucaria araucana
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA) (España), 2011)Cross-species amplification of microsatellites is a common procedure to obtain suitable markers to be used in population genetic studies. Primers designed for one (source) species are used to amplify homologous loci in ... -
Timing of nitrogen fertilization influences color and anthocyanin content of apple (Malus domestica Borkh. cv ‘Royal Gala’) fruits
(Taylor and Francis, 2011)Different timings and methods of N application modify N dynamics in the plant and could have differential effects on fruit color. To evaluate this possibility, an experiment was conducted during three seasons in a ‘Royal ... -
Postharvest quality and chilling injury of plums: benefits of 1-methyleyclopropene
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2011)The aim of this work was to evaluate the effect of 1-methylcyclopropene (1-MCP) treatment on the development of chilling injury (CI) symptoms in four plum cultivars and to determine the relationship between the climacteric ... -
Susceptibilidad de distintos clones de Red Delicious a la presencia de corazón mohoso en cosecha y durante la conservación en frío
(PHYTOMA, 2011)La principal área de producción de manzanas en Argentina es la región del Alto Valle de los ríos Negro y Neuquén. El cultivar más utilizado es Red Delicious y sus clones Red Chief, Angius y Atwood. Los objetivos de este ... -
