Full text linkEthylene control in cut flowers: classical and innovative approaches
No full textEthylene-mediated premature floral senescence and petal or flower abscission affect postharvest longevity of several species used as cut flowers. Exposure to exogenous or endogenously produced ethylene can be controlled in several ways. These include the use of ethylene biosynthesis inhibitors or ethylene action inhibitors, and ethylene removal technologies. In addition, genetic modification can be very effective in controlling ethylene synthesis and perception. We review here the potential for applications of nanotechnology to control ethylene levels and postharvest management in the flower industry. Already nanosponges have been shown to enhance efficacy of the ethylene inhibitor, 1-MCP, in several flower species. In carnation, 1-MCP included in nanosponges also allowed better control of Botrytis cinerea damage. However other applications are also considered based on successes in the use of this technology to increase agricultural production and decrease postharvest waste. Nano-metal based sensors could be used for detection of ethylene in the store and to label the product along the distribution chain. Furthermore, nanocomposites could be included as scavengers for ethylene removal in active packaging, and nanocatalysts could promote ethylene catalytic degradation in the warehouse. Nanoparticles could also be introduced into a new generation of packaging to control effects of gases and UV, and increase strength, quality and packaging appearance. This review highlights recent results on the use of nanotechnology sensu lato and potential application for cut flower vase life improvement, focusing on ethylene control strategies
From soil to soil-less in horticulture: quality and typicity
No full textIn this review, the technique of soil-less cultivation of horticultural crops is analysed, the main differences between this and traditional cultivation techniques are described, and the advantages and disadvantages of each method in relation to the others are identified. Soilless cultivation has revolutionised various sectors of vegetable and
floriculture production, and recent years have also seen interest being shown by Italian fruit crop producers, particularly those involved in
table grape viticulture. The various issues related to the use of this technique are described in relation to the needs of the substrate, water
management, and mineral nutrition of the different species, and to the fact that not all species are suitable for the application of soil-less cultivation. Finally, since the soil-less system is strongly influenced by Man and is increasingly conditioned by this, the links between the final product and the territory where it is grown appear to be very limited. This is particularly true in Italy where, for certain protected geographical indication food products, soil-less cultivation is prohibited
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
