چکیده :

and yield of medicinal plants, and the use of natural compounds to enhance plant resistance is essential. This study evaluated the effect of wood alcohol application on seed germination and early growth of lemon balm (Melissa officinalis) under different soil textures and irrigation regimes in 2025. The experiment was conducted as a three-factor factorial design including wood alcohol application (absence and presence), soil type (light/sandy and heavy/clay), and irrigation interval (every 2, 4, and 6 days) with three replicates. Results showed that drought significantly reduced germination and early growth parameters. Application of wood alcohol improved germination rate, shoot length, leaf number, and fresh and dry biomass. The highest growth was observed in light soil with 2- and 4-day irrigation intervals, with no significant difference between them. In heavy soil, wood alcohol mitigated the negative effects of drought and enhanced early plant growth. The findings indicate that wood alcohol can increase plant resistance under drought stress conditions. In addition to improving early growth, it may also enhance the final yield of lemon balm. This study confirms the effectiveness of wood alcohol as a useful tool in sustainable cultivation of medicinal plants
