Cercetarea atitudinilor tinerilor fața de turismul gastronomic orientat spre un stil de viață sănătos în Moldova [Articol]
(Universitatea de Stat din Moldova, 2024) Buzdugan, Adriana; Nepotu, Lucia
In an era where health and nutrition concerns are increasingly emphasized, understanding young people's preferences and perceptions regarding healthy eating within traditional gastronomic frameworks becomes crucial. This study explores the attitudes of Moldovan youth toward healthy gastronomic tourism, focusing on its promotion and integration within traditional Moldovan cuisine. Using a quantitative survey method, data was collected from 176 respondents aged 19 to 25, assessing their interest, perceptions, and barriers related to healthy eating in gastronomic tourism. The findings reveal a high interest among young people in exploring healthy gastronomic experiences, with quality, authenticity, and health being the most valued attributes. However, significant barriers such as high food costs and cultural preferences for traditional dishes were identified. The results underline the need for strategic initiatives to promote healthy gastronomic tourism by adapting traditional recipes and enhancing public awareness of their nutritional benefits. This study offers practical recommendations for developing sustainable and health-oriented gastronomic tourism in Moldova, leveraging the cultural and culinary heritage of the country.
Monitoring and evaluation tools for tourism activities [Articol]
(Universitatea de Stat din Moldova, 2024) Bulat, Veronica
Monitoring and Evaluation (M&E) tools are vital in ensuring sustainable development within the tourism sector, especially in regions where tourism plays a critical role in economic and cultural preservation. This paper explores the efficiency of various M&E tools implemented in Southern Europe and Moldova, examining their role in addressing challenges such as environmental sustainability, cultural preservation, and community engagement. Results indicate that tools leveraging advanced technologies, such as Smart Tourism Analytics and the European Tourism Indicator System (ETIS), are the most effective. However, moderate performance in community-based and sector-specific monitoring highlights the need for enhanced integration and capacity building. These insights emphasize the importance of adopting comprehensive, technology-driven M&E frameworks to foster sustainable tourism practices globally.
Initiation of in Vitro cultures of heuchera × hybrida [Articol]
(Technical University of Moldova, 2026) Chițan, Larisa; Tabăra, Maria; Ghereg, Melania
Background: In vitro micropropagation is a branch of plant biotechnology that encompasses methods for propagating plants through cultures of cells, tissues and organs, offering efficiency far superior to conventional propagation techniques. Aim of the study: The present study aimed to initiate and multiply in vitro the species Heuchera × hybrida to produce high-quality, genetically uniform and contamination-free planting material within a relatively short time. Materials and methods: The experiments were conducted in the Embryology and Biotechnology Laboratory at the “Alexandru Ciubotaru” National Botanical Garden (Institute) of MSU. The cultivar ‘Regina’ was selected for inoculation, being appreciated for its ornamental qualities and suitability to the pedoclimatic conditions of the Republic of Moldova. This cultivar is fast-growing and combines attractive foliage with abundant flowering. For in vitro culture initiation, plant material was collected from donor plants in early May, during active vegetative growth. Three types of explants were tested: apical meristems with leaf primordia, petiole segments and petiole segments with leaf primordia. Explants were excised and inoculated under strict aseptic conditions to ensure culture sterility and to initiate in vitro regeneration. The biological material was disinfected using a 0.1% diacid solution for 9 minutes. Results: Multiple formulations of Murashige & Skoog (MS) agar medium, supplemented with the cytokinin 6-benzylaminopurine (BAP) at various concentrations (BAP 0.1–0.5 mg/L), were evaluated for culture initiation. The highest frequency of viable explants was achieved using petiole fragments with leaf primordia. No contamination was observed with this inoculation protocol. In contrast, explants consisting of apical meristems with leaf primordia exhibited a high contamination rate of 30-40%. Although the inoculation of petiole fragments did not show contamination, it failed to produce microclones, unlike the protocol using petiole fragments with leaf primordia. Conclusions: Overall, the results suggest that the use of petiole fragments with leaf primordia, 1.0-1.5 cm in size, proved to be an efficient and proliferative material for the in vitro multiplication of this species.
Rolul managementului evenimentelor in promovarea unei destinații turistice [Articol]
(Universitatea de Stat din Moldova, 2024) Hămuraru, Maria
Event management plays a pivotal role in enhancing the appeal and visibility of tourist destinations by creating unique experiences that attract visitors and foster long-term engagement. This paper explores the strategic importance of event management in the tourism industry, focusing on its ability to diversify the destination’s offerings, strengthen its brand image, and stimulate local economic growth. Through the successful planning and execution of cultural, sporting, and business events, destinations can position themselves as vibrant and dynamic locations, capable of meeting the evolving demands of global tourists. Furthermore, effective event management promotes stakeholder collaboration, enabling public and private entities to contribute to sustainable tourism development.
Antioxidant biomarkers in assessing maize germination and seedling growth following exposure to negative temperature stress [Articol]
(Technical University of Moldova, 2026) Cauş, Maria; Borozan, Pantelimon
Background: In the current climate change environment, many breeding programs in Northern Europe are focused on developing cold-resistant maize genotypes. In this context, it is important to study and understand the morphophysiological and biochemical traits of maize that facilitate adaptation to such conditions, as the resulting information can be used for further improvement of breeding material. Therefore, five hybrids were evaluated for their response to negative temperature stress (NTS) at −4°C for 16 h before germination, followed by growth at 26°C for 7 days. The aim of the study was to determine the role of antioxidant system components in ensuring the defensive potential of maize seedlings with different levels of resistance to a specific dose of negative temperature during the early stages of ontogenesis. Materials and methods: Seeds of different maize hybrids used in this study were provided by the Public Institution “National Center for Seed Research and Production,” Pașcani, Republic of Moldova. Before germination, maize seeds were exposed to a specific dose of subzero temperature (−4°C) for 16 h. Germination, seedling growth and development were carried out under controlled conditions with regulated air temperature. Morphological and physiological parameters, as well as antioxidant system components, including peroxidase and catalase activities, total polyphenol and flavonoid contents, ascorbic acid, and malondialdehyde (MDA), were determined in the seedlings. Results: Data were obtained on the role of antioxidant system components in providing the protective potential of maize seedlings with varying levels of resistance to NTS. The results revealed a significant (P<0.05) decrease in growth parameters such as seminal root length, plant height (cm), and fresh seedling biomass (g) caused by NTS. However, a significant (P<0.05) increase in lipid peroxidation was observed. Changes were also recorded in the activities of antioxidant enzymes, including catalase, benzidine peroxidase, and ascorbate peroxidase, as well as non-enzymatic antioxidant compounds, such as total phenolic compounds, flavonoids, and ascorbic acid. Conclusions: The study showed that pre-treatment of maize seeds with negative temperature (−4°C) for 16 h significantly affected germination, growth, and antioxidant metabolism in the seedlings. Antioxidant enzymes and compounds played a crucial role in protecting plants against oxidative damage. However, the hybrids responded differently depending on their genetic background.
