Paulownia Tomentosa, a Fast Growing Timber

Abstract

The fast growing woody crops are a very important source for the generation of the bioenergetics biomass. Paulownia sp. Is a plant part of this group, and because of its fast growth, multiple values and high adaptability with climate conditions, is set recently in the centre of the intention. Paulownia is one of the fastest growing species in the world with low concentration of ash, sulphur and nitrogen and high calorific energy from its wood. It is considered as an energetic crop adequate for the production of the solid biocarburants and the bioethanol. The cultivation of the Paulownia because of the high absorption of CO2 from the air, to support the fast growth of the biomass, is considered as an effective mean to soften the climacteric changes. The plant is also considered as suitable to improve the abandoned lands when its cultivation is concentrated to the biomass production. The genus of Paulownia (Scrophulariaceae) is autochthones species of China and East Asia and as such is not found naturally in Albania. To study the regionalization possibilities of this species in the Korça climacteric conditions, aiming its cultivation according the fast growth coppice system were planted in 2014 in Cangonj (Devoll) 300 seedlings of P. tomentosa in a distance of 1 x 1 m. during the year 2015 were planted other 400 seedlings prepared with seeds. This article deals with the preliminary data of the regionalization performance of this high energetic value crop.

The Prospect of the Use of Energy Crops for Biological Reclamation of Disturbed Lands

“…According to studies [30], this crop ought to be used in the reclamation of developed peatlands. Considerable attention was paid to this crop for the rehabilitation of the produced peatlands in Finland, where its positive impact on the ecological component, in particular, the improvement of the use of nutrients from the soil was noted.…”

Ґрунтова схожість насіння павловнії повстистої Paulownia Tomentosa (Thunb.) Steud. різного географічного походження

“…Водночас, обмежувальним чинником поширення породи є температурний режим місцевості. До того ж, у зимовий період інтродуцент може переносити від'ємні температури до мінус 25 °С, проте ранні осінні заморозки призводять до обмерзання ще не здерев'янілих пагонів, а пізні веснянідо загибелі молодих паростків та відсутності плодоношення (Hakan & Kol, 2010;Hugo et al, 2013;Icka, Damo & Icka, 2016;Woods, 2008;Zhu et al, 1986).…”

“…Плантаційне вирощування павловнії повстистої та її гібридів здійснюють впродовж останніх 40 років як у країнах Південно-Східної Азії (на батьківщині породи), так і в інших країнах Азії, Європи (рис. 1), Північної та Південної Америки і Австралії (Hakan & Kol, 2010;Hugo et al, 2013;Icka, Damo & Icka, 2016;Woods, 2008;Zhu et al, 1986). Карту поширення плантацій представників роду Paulownia у країнах Європи зроблено на основі аналізу літературних джерел.…”

Non-Native Invasive Species as Ecosystem Service Providers

“…P. tomentosa became important as a biofuel crop because of its fast growth rate and high wood quantity generated in a short time period [38]. Timber biomass contains high cellulose and hemicellulose concentrations which are the main source of ethanol production [39].…”

“…Therefore, this species is highly preferred for the production of raw material for biofuel [40]. Studies have shown that the calorific value of P. tomentosa timber biomass is higher than that of coal (20.90 and 14.64 kJ/g, respectively) and thus more environmentally friendly [38,41].…”
