“…Although Paulownia currently belongs to the Paulowniaceae family, it was previously classified as a member of Scrophulariaceae [ 16 ]. The total number of Paulownia species is not universally agreed upon; depending on taxonomical classification, this number can range from 6 to 17 [ 6 ]. Li et al [ 26 ] define eight species: P. tomentosa , P. coreana , P. kawakamii , P. fortunei , P. elongata , P. catalpifolia , P. australis , and P. fargessi .…”

“…Usually, a mature Paulownia grows to a height of 20–30 m; the tallest registered specimen was 50 m [ 3 ]. The trunk is typically around one meter thick but can reach two meters in suitable environmental conditions [ 6 ]. Root systems of Paulownia trees are well-developed and can grow up to a depth of 8 m. The upper section of the roots is densely packed, branched, and dichotomous.…”

“…It is also known as the princess tree, royal tree, Kiri tree, empress tree, and phoenix tree [ 3 , 4 ], while its Chinese name is 泡桐 (pāo tóng) [ 5 ]. The genus Paulownia is believed to comprise 6 to 17 species depending on taxonomic classification [ 6 ]. Of these, P. tomentosa , P. elongata , P. fortunei, and P. catalpifolia are considered the most popular [ 4 ].…”

“…Due to their fast growth rate and adaptability, they are considered invasive species in some countries. However, most of the risks could be attenuated by planting hybrids that produce infertile seeds (e.g., Clone in vitro 112) [ 1 , 6 ]. Paulownia can adapt to varied environmental conditions, and it has a fast growth rate and exceptional regenerative abilities; a cut tree trunk can regrow up to 2–4 m in one year [ 7 ].…”

“…It has a faster growth rate than other species of Paulownia and can tolerate a wide range of temperatures, which makes it a convenient and profitable biomass and bioenergy crop [ 25 ]. Since it has infertile seeds, planting Clone in vitro 112 does not carry any risks of it spreading uncontrollably and becoming invasive [ 6 ].…”

Paulownia spp. is a genus of trees in the Paulowniaceae family. It is native to southeastern Asia (especially China), where it has been cultivated for decorative, cultural, and medicinal purposes for over 2000 years. Depending on taxonomic classification, there are 6 to 17 species of Paulownia; P. tomentosa, P. elongata, P. fortunei, and P. catalpifolia are considered the most popular. Nowadays, Paulownia trees are planted in Asia, Europe, North America, and Australia for commercial, medical, and decorative purposes. Lately, growing interest in Paulownia has led to the development of various hybrids, the best-known being Clone in vitro 112, Shan Tong, Sundsu 11, and Cotevisa 2. Paulownia Clone in vitro 112 is an artificially created hybrid of two species of Paulownia: P. elongata and P. fortunei. The present review of selected papers from electronic databases including PubMed, ScienceDirect, and SCOPUS before 15 November 2022 describes the phytochemical characteristics, biological properties, and economic significance of various organs from different Paulownia species and hybrids, including P. tomentosa, P. elongata, P. fortunei, and Paulownia Clone in vitro 112. Many compounds from Paulownia demonstrate various biological activities and are promising candidates for natural preparations; for example, the leaves of Clone in vitro 112 have anti-radical and anticoagulant potential. However, further in vivo studies are needed to clarify the exact mechanism of action of the active substances and their long-term effects.

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

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.
