“…Therefore, globally, using Paulownia as a significant component of biomass production requires special attention in nations where the growth of hybrids that could compete with native species is encouraged. In recent reports, Iran, due to its field experience, has reported its ability to plant Paulownia in an area of approximately 16 × 10 4 km 2 (Galán-Martín et al, 2015;Abbasi et al, 2020). More importantly, several nations are beginning to advance in this area, such as Portugal (Abreu et al, 2020), Iran (Abbasi et al, 2020), Spain (Parra-Lopez et al, 2015;Pleguezuelo et al, 2015), Romania (BUZAN et al, 2018), Italy (Testa et al, 2022), Serbia (Janjić and Janjić, 2019), Ukraine (Morozova et al, 2020;Kaletnik et al, 2021), Northern Ireland (Woods, 2008a;Olave et al, 2015), and Kyrgyzstan (Thevs et al, 2021).…”
