La scelta varietale ha ripercussioni economiche di lungo termine. In tale prospettiva, con KULTIVAS vorremmo proporre un approccio data-driven a questo importante problema del settore melicolo. In questo progetto, dati storici selezionati sulla produttività e qualità delle mele, moderni sistemi di gestione dei dati, algoritmi e tecniche di apprendimento automatico sono stati impiegati adottando un approccio multidisciplinare che coinvolge esperti di diversi settori, quali agronomia, fisiologia, climatologia e informatica, per valutare l'idoneità sito- specifica alla coltivazione di determinate varietà di mele. Il modello di previsione sviluppato nell’ambito del progetto si basa su dati climatici e topografici interpolati spazialmente, oltre che su dati di produzione e qualità delle mele provenienti da diverse cooperative altoatesine. Usando informazioni spazialmente disponibili sul clima, il modello è in grado di stimare vari parametri di produzione, come calibro, colore e resa. La previsione degli indicatori predetti dal modello statistico è più̀ precisa quanto più̀ il set di dati di training copre la variabilità̀ climatica e topografica delle aree di indagine. In aree con caratteristiche al di fuori di questa variabilità, il modello avrà un potere predittivo limitato. I risultati di questo studio saranno arricchiti con dati provenienti da altre località e valutando ulteriori algoritmi per la corrispondenza geografica dei dati di cernita, in quanto il set di dati influenza in maniera importante i risultati.","PeriodicalId":325047,"journal":{"name":"Laimburg Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115540639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zatelli, Flavia Bianchi","doi":"10.23796/lj/2022.007","DOIUrl":"https://doi.org/10.23796/lj/2022.007","url":null,"abstract":"Several fresh-cut apple snacks are available on the market, and their color is highly relevant for consumers. As apple slices brown very quickly after cutting, dipping them in an antioxidant solution for a few minutes is common to avoid this phenomenon. However, this procedure has some limitations. Using the same solution for several immersion cycles over several hours can lead to cross-contamination and microbial growth. In addition, osmotic exchange phenomena in the immersion tank lead to a reduction in the concentration of the active ingredients of the antioxidant solution over time, which requires continuous readjustment of the concentrations. These aspects, together with the large quantities of exhausted antioxidant solution to be disposed of, are limiting factors that drive the search for alternative and more sustainable methods than dipping. In this work, a comparison between a conventional dipping treatment of fresh-cut apples and spraying at increasing volume of antioxidant solution was performed. Color, considered as the quality reference parameter, was visually assessed (occurrance of dark spots) and CIE Lab colorimetric indices were measured over a five-day experimental period. Based on dark spots and the changes in brightness (Δ L*), hue angle (Δ h) and chroma (Δ C*), some of the spraying treatments applied were found to be comparable to dipping in controlling browning. For all treatments, high intra- and inter-batch variability and within slices of the same apple was observed concerning both instrumental data and dark spots development, indicating that further investigation is needed to validate this result and to apply this procedure at an industrial level.","PeriodicalId":325047,"journal":{"name":"Laimburg Journal","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121435774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phytophagous pest Halyomorpha halys (Stål), originated from north-eastern Asia, is by now introduced in several countries worldwide. Its highly polyphagous behaviour, paired with a relatively high reproduction rate under favourable conditions, makes it an im-portant pest of several agricultural crops. In South Tyrol (Northern Italy), one of the largest con-tiguous apple growing regions in Europe, first adults had been reported in March 2016. Active monitoring techniques, as well as the implementation of a Citizen Science approach, enabled to follow up the spread and settlement of stable populations of H. halys in South Tyrol. Since its first detection, H. halys showed a rapid expansion of colonized area and an increase in population densities from year to year. Established populations coincide mostly with the main apple growing area, namely the Etsch Valley from Meran to Salurn, mainly occupying lower altitudes between 200 and 500 m a.s.l. Since 2019, a further spreading in the western and eastern parts of South Tyrol can be observed. In apple orchards H. hals showed generally a continuous presence throughout the growing season from April to October, with population peaks in the late season. On the other side, populations dynamics and densities of adults and nymphs differ significantly between years ans sureveyed sites. The findings indicate that the application of pheromone baited traps is a good tool for an area wide approach in or-der to get information on its spreading, to pinpoint the main distribution area and to draw a general picture of the population dynamics at a larger scale. On the other side, an area wide approach should be interpreted cautiously, as real population densities might be underesti-mated and do not depict the real situation for singular orchards.","PeriodicalId":325047,"journal":{"name":"Laimburg Journal","volume":"1942 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127460135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
