102. 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.

105. 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.

109. The acute effect of mental fatigue on strength endurance in young kickboxersEsra Kürkcü Akgönül, Gökmen Özen, 2024, izvirni znanstveni članek Povzetek: This study was conducted to examine the acute effects of Mental Fatigue (MF) on strength endurance in well-trained young kickboxers. A total of 17 female/male athletes (age: 15.76±1.44 years; height: 167.06±8.63 cm; body weight: 62.03±10.63 kg) par-ticipated. The Repeated Measurement Design was used. Accordingly, the participants had 3 sessions; pre-preparation, control, and mental fatigue. In the pre-preparation session, demographic information and one repetition maximum (1RM) for bench press (BP) and squat (SQ) exercises were taken. The athletes’ strength endurance was perfor-med until 60% of 1RM exhaustion; the number of repetitions (NOR) and movement time (MT) were recorded. In the MF session, the participants were subjected to a 30-minute Stroop task before the strength test. In order to determine the differences in NOR and MT between the sessions and the differences in measurements according to gender, the Paired sample t-test was used. The presence of MF significantly reduced SQ-NOR by 34.5%, SQ-MT by 36.88%, BP-NOR by 22.71%, and BP-MT by 28.27% (p<0.05). Based on gender, MF had a significant negative effect on SQ-NOR, SQ-MT, and BP-MT in women and men and on BP-NOR only in women athletes (p<0.05). As a result of the research, 30-min MF application negatively affects the lower and upper extremity strength endurance performance in young kickboxers. In this respect, young kickboxers should avoid activities that will cause mental fatigue such as using digital screens or solving questions or puzzles for social media purposes for 30 min or more before train-ing and competition, which will prevent possible muscular performance loss.

110. Dietary habits of shooting athletes : a comparative study of Slovenian and foreign athletesTadeja Jakus, Nika Černe, Mojca Stubelj, 2024, izvirni znanstveni članek Povzetek: Purpose: Shooting is a sport in which dietary habits and the timing of meals is not often represented. The aim of this paper is to compare the dietary habits, timing of meals and training frequency of Slovenian and foreign athletes. Methods: The sample included 88 shooter athletes (35 Slovenian and 53 foreign athletes), aged 14 to 60, who participate in competitions. Data by dietary habits, diet, training and BMI were collected via a questionnaire. Results: Athletes train and compete most frequently using an air rifle. Foreign athletes train more often and spend more time training than Slovenian athletes (p < 0.001). The average BMI was 24.9 ± 4.9 kg/m2 and was higher in athletes who competed at national level (26.8 ± 5.6 kg/m2) compared to international level (23.0 ± 3.1 kg/ m2) (p = 0.022). We found a difference between the groups in lunch (p = 0.041), morning (p = 0.020) and evening (p = 0.008) snacks. Slovenian athletes reached for food during training less frequently than foreign athletes (p = 0.007). More than half of the athletes (p < 0.001). Conclusions -athletes tend to train more frequently, have better nutritional planning and eat more meals after training than their Slovenian counterparts.
