Abstract
To compensate for higher production costs in winter, tomato cultivars with better taste and flavor characteristics and higher selling price are often cultivated. Tomato taste and flavor is reduced during cold storage, however the reduction is often cultivar dependent. Little is known how postharvest storage conditions affect flavor and taste quality of tomatoes cultivated in greenhouses during wintertime at high latitudes. This study was aimed to analyze how postharvest storage conditions affect composition of flavor-related volatile organic compounds (VOCs) and taste quality of tomato fruits. Tomato cultivars ‘Brioso’, ‘Flavance’, ‘Piccolo’, ‘Sweetelle’, ‘Sweeterno’ were grown in greenhouses with artificial lightning in southwestern Norway during wintertime and were collected ripe. Experimental set up was simulating shortest postharvest chain for southwestern Norway, including harvest day (18°C for one day, in darkness), packaging and transport (12°C for 3 days, in darkness), retail (18°C for 2 days, with light) and consumer storage in either a refrigerator (4°C for 4 days, in darkness) or a kitchen counter (20°C for 4 days, with light). VOC composition of tomato fruits was analyzed using HS-SPME-GC-MS. Fruit quality parameters including sugars, titratable acidity (TA), dry matter content, firmness and pigments were analyzed. Laboratory results were compared to responses from a taste panel. Firmness and TA were lower for fruits after storage at both conditions compared to fresh fruits. Relative concentrations of the most flavor-related VOCs were lowest for fruits after storage at both conditions. The reduction was higher when fruits were stored at 4°C. Fruits from cultivars ‘Sweeterno’ and ‘Piccolo’ showed the lowest difference in relative VOC concentration at 4°C. Perceived overall tomato taste generally decreased after storage. Overall, storage at 20°C is favorable for preserving flavor of most winter-produced tomato cultivars, but disadvantageous for maintaining their firmness and TA.

Abstract
The morphological ontogeny of Zachvatkinibates svanhovdi A. Seniczak & S. Seniczak, 2023 is described and illustrated. The juveniles of this species are light brown with slightly darker colour on the prodorsum, gastronotal shield, surrounding of gla opening, and legs. The larva has 12 pairs of gastronotal setae, most are of medium size and barbed; the nymphs have 15 pairs, most are short and smooth. In all juveniles, the setae of c-series are inserted on unsclerotized integument. In the larva, the pygidial shield is absent but, in the nymphs, the gastronotal shield is present and the setae p2 and p3 are inserted on unsclerotized integument. In the larva, a humeral organ is absent but is present in the nymphs.

Thiago InagakiAbstract
The Norwegian Institute of Bioeconomy Research (NIBIO) has been working on many fronts to promote sustainable agriculture. As part of the Department of Biogeochemistry and Soil Quality, I will present initiatives and progress made by the NIBIO Institute in promoting soil organic matter persistence and sustainable agriculture in Norway and worldwide. Two major challenges have been targeted with a focus on Norway: waste generation by several industries (e.g., agriculture, forestry, and fishery) and the short time of the cropping season in the country due to climatic constraints. To solve these issues, we are working on several projects focused on re-utilizing waste products by producing organic fertilizers, optimizing these fertilizers (e.g., biochar N-enrichment), and improving current cropping systems with crop diversification. Our main objective is to investigate the benefits of these practices in improving soil quality and crop productivity and enhancing soil organic matter persistence. Our work on soil science also goes beyond Norwegian and Nordic conditions. Among our international collaborations, we are currently working on a multi-institution bilateral project between China and Norway to promote the restoration of a semi-arid ecosystem in Inner Mongolia. We are also often engaging in project proposals for promoting sustainable agriculture in tropical regions. To develop these ideas, we promote a combined approach of spectroscopy techniques in collaboration with other institutions, such as nanoscale secondary ion mass spectrometry (NanoSIMS) in partnership with the Technical University of Munich (TUM) and NMR spectroscopy in partnership with the National Research Council of Italy (CNR-Pisa). Also, our research facilities count on good infrastructure, focusing on incubations with 13C and 15N labeled amendments and 13C pulse labeling.
