374. Fire safety of timber buildings – the case of photovoltaic systems : a recent exampleNik Rus, Andrea Lucherini, Grunde Jomaas, Mohammad Derikvand, 2025, drugi znanstveni članki Povzetek: Photovoltaic (PV) systems play an important role in reducing society’s dependence on carbon-based energy sources, and their coupling with timber buildings is an interesting and expected solution for meeting sustainability requirements in the modern built environment. However, both PV systems and timber structures have unique fire safety challenges, and their combination may introduce additional risks. Therefore, relevant fire hazards associated with each of the technologies and their pairing are discussed. The findings highlight the importance of revising fire testing standards and developing tailored safety measures to identify and manage these risks.

376. Differences in bark anatomy between stem and branches of Olea europaea L.Jožica Gričar, Klemen Eler, 2025, izvirni znanstveni članek Povzetek: In addition to morphological characteristics, bark anatomy can provide a more detailed picture of the function of different bark tissues. In the current study, we examined and compared the bark anatomy of the stem and branches of 20-year-old Olea europaea L. We hypothesised that there are differences in bark anatomical traits between stem and branches, which reflect their functional differences in a tree. We found that the widths of bark, phloem + cortex, and periderm significantly differed in the stem and branches; all tissues were wider in the stem. The size and area of the sieve tubes and the proportion of sclerenchyma in the oldest part of the phloem + cortex differed in the stem and the branches. At the same time, numerous similarities in the stem and branch bark anatomy were observed: (1) annual phloem increments could not be determined in the youngest phloem adjacent to the cambium; (2) a distinction between non-conducting and conducting phloem was not possible because the collapse of sieve tubes in non-conducting phloem was not prominent enough to be determined visually; (3) dilatation of rays and axial parenchyma was locally clearly visible; (4) the proportion of phloem and cortex changed with distance from the cambium; secondary phloem constituted the entire bark tissue adjacent to the cambium, while cortex prevailed next to the periderm and (5) phelloderm width did not change with bark age. Differences in the bark structure of the stem and branches of olive trees imply functional differences between these two tree parts and point to different ecological contexts. Moreover, branch bark trait values cannot be used to extrapolate to the main stem bark (or vice versa). Differences support previous studies that have reported that different tree parts are exposed to different microenvironments.

379. Yield and silage quality of winter legume cover crop mixtures without nitrogen fertilization in springMarko Zupanič, Tomaž Žnidaršič, Miran Podvršnik, Vilma Sem, Boštjan Kristan, Ludvik Rihter, Branko Kramberger, 2025, izvirni znanstveni članek Povzetek: A field experiment was conducted in two seasons (2019–2020 and 2020–2021) at three locations in Slovenia (Rogoza, Fala, and Brežice) to evaluate the yield and silage quality of winter cover crops (WCCs). The experiment included Italian ryegrass (IR) in pure stands, fertilized with nitrogen in spring, and mixtures of crimson clover (CRC), red clover (RC), and IR+CRC+RC without nitrogen fertilization in spring. The highest dry matter yield (DMY) was observed in IR+CRC+RC (4.98 t ha−1). For fresh feed, the CRC+RC treatment had significantly higher (p < 0.05) crude protein (208 g kg−1 DM), nitrate nitrogen (116.7 mg kg−1 DM), and buffering capacity (1290 mmol kg−1 DM) but significantly lower (p < 0.05) dry matter (128 g kg−1) and water-soluble carbohydrates (121 g kg−1 DM). For silage, the CRC+RC treatment had significantly lower (p < 0.05) dry matter (476 g kg−1 silage), metabolic energy (9.65 MJ kg−1 DM), net energy of lactation (5.77 MJ kg−1 DM), and neutral detergent fiber (375 g kg−1 DM) but higher ammonia nitrogen (66.5 g kg−1 of total nitrogen), crude protein (158 g kg−1 DM), and acid detergent fiber (279 g kg−1 DM). No significant differences (p > 0.05) were found among treatments for acetic, lactic, and butyric acid, crude fat, pH, and soil mineral nitrogen (Nmin). The results of the study show that the same or higher DMY and a comparable quality of highly wilted silage can be produced with mixed Italian ryegrass and clovers compared with those of Italian ryegrass in pure stands. The experiment aimed to determine whether clover-based mixtures can achieve comparable silage quality and dry matter yield without spring N fertilizers compared with those of pure stands of Italian ryegrass fertilized in spring.
