Changes on the cell wall composition of tree-ripened “Bartlett” pears (Pyrus communis L.)
(Elsevier, 2012-11)Most of the European pear cultivars fail to develop a desirable texture when ripening on the tree. In order to identify some biochemical anomalies that might be associated with this phenomenon, the main differences in cell ... -
Cladosporium species causing “Cladosporium rot” on “Bosc” pear fruit in Argentina = Especies de Cladosporium causantes de podredumbre en peras «Bosc» en Argentina
(Elsevier, 2020-06)“Cladosporium rot” on “Bosc” pear fruit during cold storage causes significant economic losses and has been reported in recent years in the productive valleys of Río Negro and Neuquén. The species involved were not determined. ... -
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, ... -
Comportamiento productivo de diferentes combinaciones cultivar portainjerto de peral en el Alto Valle de Río Negro y Neuquén
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-04)Con el objetivo de evaluar el comportamiento vegetativo y productivo de diferentes combinaciones cultivar-portainjerto de peral en la zona del Alto Valle de Río Negro y Neuquén se planteó un ensayo con cinco portainjertos: ... -
Compositional Changes in ‘Bartlett’ Pear (Pyrus communis L.) Cell Wall Polysaccharides As Affected by Sunlight Conditions
(American Chemical Society, 2011-10-07)Preharvest conditions can have a great impact on fruit quality attributes and postharvest responses. Firmness is an important quality attribute in pear, and excessive softening increases susceptibility to bruising and ... -
Effect of pre and postharvest application of fungicides on postharvest decay of Bosc pear caused by Alternaria—Cladosporium complex in North Patagonia, Argentina
(Elsevier, 2017-11-18)In recent years, decays by Alternaria spp. and Cladosporium spp. constituted a hazard to “Bosc” pear fruit during cold storage with significant economic losses (about 50%) in the Rio Negro and Neuquen Valleys. Studies with ... -
