New scientific knowledge in kiwifruit storage using sanitization systems (Ionny®) avoiding postharvest chemical treatments
No full textLoss of produce during commercial kiwifruit storage is so high as to require the
adoption of specific techniques and preventive measures. Postharvest curing
techniques alone are not sufficient to guarantee valid economic results, particularly
when fruits are harvested in high-humidity environmental conditions due to rain or
heavy dew. The incidence of rot due to Botrytis spp. penetrating the pulp at the
detachment point of the stalk can reach high percentages (10-20% of damaged fruit),
and specific postharvest chemical treatment known as drenching is required. As
verified in the past, an alternative to the use of chemicals, with air sanitation of the
storage environment using an ionizer (Ionny®), is possible. Tests carried out during
the 2016-17 season have confirmed the validity of this technique in CA storage
conditions (-0.5/-0.7°C, RH>90%, CO2 3-4%, O2 2.5-3%, C2H4<0.02 ppm) alongside
curing, with results comparable to those obtained using the chemical treatment
fenhexamid in a drencher. A batch of ‘Hayward’ kiwifruit produced in the Trentino
(Italy) area was divided into three groups: 1) treatment with fenhexamid + curing +
CA; 2) curing + CA in an ionized environment; and 3) no treatment + curing + CA
(TEST). The trial found over 15% of fruits infected with Botrytis spp. in group 3, and
100% healthy fruits in groups 1 and 2. These results, as well as confirming the
outcome of previous trials, have also highlighted that group 2 (CA storage with air
sanitized by Ionny®) produced the best results (firmness, total acidity) both at the end
of storage and also after 8 d shelf-life at room temperatur

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
