The presented study evaluates the potential of Juniperus communis L. for ecological restoration of degraded forest ecosystems of Azerbaijan. These degraded areas are results of soil erosion, loss of biodiversity, and climate-related conditions. J. communis, a widespread coniferous species, can act as a significant species for forest regeneration due to its adaptability and key ecological functions. J. communis seeds were collected from five different regions of Azerbaijan, representing different climatic and altitudinal zones. This experiment was performed to analyze the effect of low temperature (5°C) and scarification on germination percentage of Juniperus communis L. (Cupressaceae Bartl.) seeds collected from different regions. Seeds collected from Nakhchivan, Khizi, Turyanchay, Shamkir and Guba regions were subjected to cold stratification for 0, 4, 8, 12 and 16 weeks, and the effect of scarification was additionally evaluated. The highest germination at 5°C was observed during the 8-week stratification period and varied by region. Scarification significantly increased germination rates, with the highest results recorded in the 8-week period. Overall, seed germination percentages were considerably higher under scarification treatment compared to conventional cold stratification. The results can easily demonstrate that both cold stratification and scarification serve as effective pre-germination techniques for overcoming deep physiological dormancy in Juniperus communis seeds. However, the enhanced response observed with scarification highlights its greater potential in promoting rapid and uniform germination. Among all treatment durations, the highest germination rate was recorded after 8 weeks of pretreatment, suggesting that this period represents the optimal physiological period for dormancy release and metabolic activation of seeds. These findings hold significant ecological and practical importance, particularly for restoration biology and forestry management. The evidence obtained in this study provides valuable guidance for designing successful artificial regeneration strategies and afforestation programs involving Juniperus communis, especially in arid and semi-arid ecosystems, where natural regeneration is often limited due to harsh environmental conditions and low seedling establishment rates. Therefore, incorporating scarification combined with an 8-week cold stratification period can be recommended as an effective approach to enhance germination success and support long-term conservation and reforestation initiatives for juniper populations.
