“…Actually, this genus is suitable to reclaim abandoned farmlands or to restore soils, where special emphasis is focused on biomass production [10]. For this reason, the genus Paulownia has been used in several recent studies which have been focused on its potential for timber production [10], its use in agroforestry practices and intercrops [11], biotechnology and in vitro cultivation [12], soil activity in Paulownia plantations [13], and the chemical composition of its wood [14]. Regarding biomass production, a recent research analyzed the woody biomass yield for clones monitored at different locations in south Spain.…”

Abstract:In semi-arid regions, afforestation with fast-growing species cultured with low irrigation can be an effective approach for environmental protection. An experiment was conducted to evaluate the stem biomass production of Paulownia in a semi-arid climate and clay soils under contrasting low-irrigation and fertilization treatments. The stem biomass at the stand level was estimated by applying allometric equations fitted in sample resprouts and inventory data. The results show that biomass production improved when either irrigation or fertilizer was added, but the combination of a higher dose of irrigation and fertilization did not lead to the highest biomass production; thus water availability was the main factor controlling biomass production. Under the higher dose of irrigation, the absence of a fertilizer effect would be due in part to the fertile soil, which could supply sufficient nutrients for Paulownia growth at the higher level of soil moisture. The stem OPEN ACCESSForests 2014, 5 2506 biomass estimated ranged from 2.14 to 4.50 t⋅ha −1 (lower irrigation dose without fertilization, and higher irrigation with fertilization). The greater production was similar to other studies in the Mediterranean area receiving more irrigation. Thus, this study permitted us to understand the potential of Paulownia to provide biomass in semi-arid environments with low irrigation due to water use restrictions.

“…is an indigenous genus from China that is represented by nine species (P. elongata, P. tomentosa, P. catalpifolia, P. fortunei, P. taiwaniana, P. albiphloea, P. australis, P. kawakamii, and P. fargesii) of fast growing timber trees (Hulya et al 2005;Barton et al 2007;Manuel et al 2011;Liu et al 2013b). Due to its adaptability, allowing a wide distribution, and extremely fast growth, Paulownia has become one of the most important supply species for the wood industry in China, especially after 1998, when the policy of natural forestry protection was put in force (Zhu et al 1986;Hu 1999;Chen 2003;Zhou and Li 2004;Li et al 2009).…”

The behavior of paulownia wood (Paulownia elongata) was investigated using three different ageing tests: simulated natural ageing under the influence of light under indoor conditions, temperature-induced ageing in the dark, and UV-induced ageing. Ageing effects were evaluated by color measurements in the CIE Lab system. Simulated natural ageing of wood in indoor conditions (6 months) and UV-accelerated ageing (72 h) are complex and dynamic processes, which resulted mostly in yellowing of the samples due to photo-degradation. Temperature-induced ageing (288 h at 100 C) resulted mostly in a rapid and visible darkening of the paulownia wood. Comparative in-time evolution of color changes during accelerated UV ageing testing and simulated natural ageing testing under indoor conditions allowed the estimation of an acceleration index of about 50X. Fourier transform infrared spectroscopy (FTIR) was used to examine specific chemistry changes occurring during these ageing tests. UV light from natural or artificial sources caused primarily lignin degradation followed by oxidative processes leading to carbonylcontaining chromophores. Temperature-induced partial degradation of hemicelluloses and oxidative processes resulted in the formation of chromophores containing mostly conjugated carbonyl groups. This research highlighted that paulownia wood (P. elongata) is quite sensitive to ageing under the action of light and temperature, which cause notable color and surface chemistry changes.

“…A key management system, like short-rotation woody crops, constitutes a renewable energy feedstock for biofuels, bioenergy, and bioproducts. Paulownia spp., which are considered to form short rotation forestry plantation, is a promising tool for reducing the atmospheric carbon dioxide concentration [4], [5], [6], [7]. Characterised by the presence of a C4 photosynthesis pathway involved in regulating the climate, it absorbs significant amounts of carbon dioxide and releases a large amount of oxygen.…”

Fast growing woody crops are currently a very important source for the generation of energy biomass. As short-rotation woody crops, the genus Paulownia has already attracted growing attention. These trees are used to produce biomass and reduce the carbon dioxide concentration in the atmosphere. Most projects for biomass production, however, may affect soil properties and status. For this reason, it is important to know the effects of Paulownia plantations on the microbiological properties of the soils on agricultural areas in Poland. This article provides information on plant parasitic nematodes inhabiting the root zone of Paulownia tomentosa L. in Poland. The only report of Meloidogyne hapla Chitwood, 1949 shows the potential pathogenicity of the root-knot nematodes. Furthermore, nothing is known about plant parasitic nematodes inhabiting the root zone of Paulownia tomentosa L.in Poland. Determining the trophic group of plant parasitic nematodes was undertaken by a process of centrifugation. Measurements showed a decrease in the population reproduction factor (Pf/Pi) which reached a value of 0.1. Paulownia tomentosa L. taken from seven different locations in Poland revealed the presence of M. hapla.
