“…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).…”

Due to the progressive climate change on our planet, scientists are interested in solving this issue since it threatens not only certain regions or countries but also the world’s ecosystems and economies. Therefore, minimizing carbon dioxide (CO2) emissions and reducing atmospheric levels are global priorities. Thus, it is necessary at this moment to develop an appropriate approach to reduce or stabilize CO2 levels in the atmosphere. However, CO2 capture projects are long-term, low-profitable, and high-risk environmental projects. Consequently, it is necessary to find an appropriate and sustainable CO2 capture approach that is efficient in reducing atmospheric CO2 levels while having a safe impact on the environment. Although carbon (C) is the key basic component used to produce biological compounds by photosynthetic organisms in terrestrial plants, the C pathway is a key factor affecting the capture of CO2 by photosynthetic organisms. Among photosynthetic organisms, Paulownia, a multipurpose tree, is popular around the world for its timber and its potential role in CO2 sequestration. Paulownia spp. belongs to the Paulowniaceae family and comprises a group of trees. These trees are primarily found in southeastern Asia, particularly in China, and have been intentionally grown for more than two millennia due to their ornamental, cultural, and medicinal value. The number of Paulownia species varies depending on taxonomic classification, ranging from 6 to 17. Among them, Paulownia tomentosa, Paulownia elongata, Paulownia fortunei, and Paulownia catalpifolia are the most widely recognized and favored species. The present review provides a comprehensive technical-economic scenario for the capture of one million tons of CO2 by Paulownia trees (as a terrestrial plant model, grown on 2,400 ha−1). P. tomentosa can be utilized in agroforestry systems to mitigate greenhouse gas (GHG) emissions within urban cities and emphasize the carbon storage potential of agroforestry. In conclusion, Paulownia trees as an environmental mass project showed great encouragement to investors and governments to expand these types of projects to achieve global climate goals by 2050.

“…The water productivity of paulownia and poplar in Kyrgyzstan was studied by N. Thevs et al (2021). These studies were conducted to identify the possibility of additional load on water resources of the introduced paulownia (Paulownia tomentosa × fortunei) compared to three-year-old poplar (Populus deltoides × nigra) plants.…”

“…The stem biomass of paulownia increased by 4.8 kg at an average flow rate of 2.36 l/day (water productivity 11.90 g/l). Therefore, N. Thevs et al (2021) concluded that the reproduction of paulownia will not put more pressure on the water resources of Central Asia than poplar. This refutes the negative feedback that paulownia is an invasive species and has a negative impact on other tree species.…”

Plantation forestry using highly productive and fast-growing plants involves the use of high-quality improved planting material for genetic constancy, which is solved by microclonal reproduction. However, the high survival rate and stability of plants obtained in vitro are realised as a result of post-aseptic adaptation of regenerants. Therefore, the research aims to improve the survival techniques of paulownia regenerants of the Ukrainian varieties “Feniks” and “Enerdzhy” ex vitro. The study was conducted in December 2021 on the Ukrainian paulownia varieties “Feniks” and “Enerdzhy”, cultivar “Feniks”. The survival rate, development of regenerants, and their damage by facultative saprophytic pathogens differed on substrates of organic (Eco Plus, La Flora, Jiffy, coconut peat, cotton wool) and mineral (vermiculite, perlite, sand) origin. The biological products “Rise P” and “Prestop” proved to be effective for the control of pathogenic microorganisms on substrates of organic origin. The technological feasibility of using perlite substrate is substantiated. The pathophysiology of ex vitro regenerants of paulownia under Fusarium is described. The thickness of the films used for sheltering influenced the regeneration, engraftment, microbial damage, and temperature of the wet chambers. Growing regenerants with covering films of different thicknesses showed a high survival rate in the variants with stretch films of 10 and 23 µm thickness. In the case of using polyethene films with thicknesses of 60, 80 and 100 µm, a sharp increase in temperature was observed, which was 48, 53 and 650C, respectively. At these high temperatures, most of the regenerants died, after which they were colonised by facultative saprophytes, and the tissues were completely macerated within two days. The optimal ratio of juvenility reduction and the acquisition of adaptive traits is characteristic of the second, third and fourth generation ex vitro. The expediency of propagation by stem cuttings up to the fourth generation, which preserves the regenerative ability of shoot cuttings, was substantiated. The practical results of the research are a protocol for growing paulownia plants in vitro and ex vitro on different types of substrates for use by institutions engaged in paulownia propagation

This review aimed to determine the current state of research on the growth conditions and use pertaining to paulownia wood, mainly in European countries where paulownia has been introduced only relatively recently. Several studies carried out on Paulownia hybrids have shown significant differences in the growth dynamics of individual clones in their response to local environmental and climatic conditions. For example, dry biomass production yields in the second year of cultivation range from 1.5 t ha−1 to as much as 14 t ha−1. This diversity has manifested itself not only in growth characteristics but also in the properties of the wood and the possibilities for its use. Despite having clear similarities to the genus Paulownia, the cultivation of species and hybrids under different conditions has produced varying results. The best growing conditions for this wood (that make economic sense) are in the Middle East and Southern Europe. These regions have accumulated the most experience because of the earlier establishment of the crop. Today, paulownia cultivation is dominated by hybrids with selected traits that are propagated mainly in vitro. The most commonly planted hybrids include the clones in vitro 112, Cotevisa 2 and Shan Tong. The growth results and production capacity in central European countries are lower compared to Southern Europe. Experiments on paulownia cultivation are still relatively young, mainly consisting of replicating the cultivation of hybrids developed in Asia or Southern Europe. However, agronomic procedures are being developed and reactions to local climatic conditions are being studied. It is likely that, in the next few years, the profitability of growing paulownia in these regions will become apparent.
