Effect of concentration, application volume and addition of a surfactant on response to benzyladenine as thinning agent in 'Williams' pears
(ISHS, 2011-10)Benzyladenine (BA) is an effective thinning agent for Williams pear, the most important cultivar in Argentina. The aims of this research were: to find the minimum effective BA rate for increasing fruit size in Williams ... -
Water use by drip irrigated one-year old pear trees
(ISHS, 2011-10)Crop coefficients (Kc) of pear trees ‘Abate Fetel’ were determined at EEA INTA Alto Valle during the second growing season after planting. Individual trees were placed in each of three lysimeters at the time of orchard ... -
Contributions of early season temperatures to pyrus communis 'Bartlett' fruit growth
(ISHS, 2011-10)Final size of pear fruit depends on genetics, environmental and different management factors. The aim of the present study was to examine how natural temperature fluctuations affected growth of ‘Bartlett’ cultivar fruit. ... -
Effects of trunk girdlin on fruit production, fruit size and tree vigor on 'Bartlett' pears in Río Negro and Neuquén Valley, Argentina
(ISHS, 2011-10)Fifty percent of Argentine pear production corresponds to the ‘Bartlett’ cultivar. One of the principal problems on its production is small fruit size. Excessive vegetative growth of trees can increase this problem because ... -
Effect of AVG application on fruit set, yield and fruit size in ‘Abate Fetel’ and ‘Packam’s Triumph’ pears in a semi-commercial statistical trial
(ISHS, 2011-10-31)Fruit set in pear (Pyrus communis L.) can be low and unpredictable. The aim of this study was to increase fruit set and subsequently yield in ‘Abate Fetel’ (AF) and ‘Packham’s Triumph’ (PT) pears. The influence of ... -
Study of the main points of impact during cherry handling and factors affecting pitting sensitivity
(ISHS, 2014-02-15)Pitting damage is one of the most important causes of quality loss during the postharvest life of cherries. The present work examines the effect of different factors that can affect pitting sensitivity. In a first trial, ... -
