The purpose of this research was to evaluate the seed viability of 16 Oryza sativa L. accessions including valuable endangered landraces, a breeder’s line, and an advanced/improved cultivar after 13-14 years of long-term storage. Preservation of seed samples has been conducted ex-situ at low temperatures (-18°C). The germination test (germination energy and total germination) was carried out according to ISTA methods and Kameswara (2006). Furthermore, the following variables were examined: the germination index, root length, shoot length, root-to-shoot length ratio, total seedling length, and seed vigour index. The Pearson correlation coefficient was computed to assess the linear relationship between the vigour index and seedling length. All the sixteen accessions have had a high total germination rate, in the range of 89-100%, hence there is no need for their regeneration. The germination energy and total germination showed statistically significant differences for two rice accessions at P-0.05 and P-0.01. The seed showing a high vigour index produced seedlings with higher growth rates. The Pearson correlation of the vigour index and seedling length was found to be very highly positive and statistically significant (r=0.99, p<0.001). Based on the results obtained, it can be concluded that rice as a botanical species retains high seed viability during the long-term conservation, although there are individual differences between the accessions which are due to the genetic constitution of each genotype.

Rakija is a strong alcoholic beverage, deeply rooted in Macedonian cultural heritage, where quality varies significantly between industrial, small-scale, and traditional home producers. This study evaluated sensory and chemical differences among three types of producers using 30 samples of rakija from grapes (10 per group). The chemical analysis included gas chromatography (GC) for volatile compounds and analytical methods for alcohol content, specific gravity, and extract. The sensory analysis was performed by a trained panel (6 assessors) following OIV 100-point scoring scale. Spearman’s rank correlation was used for statistical data analysis. Sensory results revealed greater variability in odour and taste (CV 14–29%). Isobutanol showed a significant negative correlation with quality (ρ = -0.43 to -0.46, p < 0.017), while extreme variability in esters (CV >100%, ethyl acetate up to 5,654 mg/L) and furfural (CV 383%) was detected. In contrast, the extract content positively influenced the balance (ρ = 0.43–0.50, p < 0.017) in all of the samples. Between the producer’s groups, the traditional samples had more unpleasant aromas due to improper distillation and fermentation, as confirmed by the chemical analysis results where ethyl acetate reached up to 5,654 mg/L. Routine sensory-chemical correlations can aid quality assessment, linking traditional heritage with modern distillation methods in Macedonian rakija production.
