“…Forest products act as substitutes for politically, socially and environmentally insecure fossil fuels. In the climate change context, agricultural greenhouse gas sinks may be instrumental in removing carbon from the atmosphere by changing the vegetation cover and improving management, switching from the conventional agricultural crops to forests [1].…”

“…As ethanol production through conversion of biomass becomes commercially viable in the future, growing short rotation woody crops (SRWC) for substituting fossil fuels may become a cost-effective strategy to combat climate change [36]. Another advantage of carbon sequestered through afforestation projects may help earn carbon credits to meet carbon reduction targets as outlined in Kyoto protocol.…”

Paulownia elongata is a short-rotation fast growing tree and is known for high biomass accumulation and carbon sequestration potential. Optimization of protocols for nucleic acid extraction, PCR, RT-PCR, and other molecular biology techniques are required for better understanding of cellulose synthesis and to assess the potential of Paulownia as a biofuel tree. The main objective of this work was to study a putative cellulose synthase amplicon expression under various environmental conditions and evaluate the potentials of Paulownia as a biofuel tree. Using cross-species PCR an amplicon representative of a putative cellulose synthase gene from Paulownia was identified. This 177-bp long DNA sequence was 46% similar with cellulose synthase genes from Arabidopsis as expected. Gene specific primers for this particular Paulownia cellulose synthase gene were designed and reverse transcription PCR was performed to confirm its transcription. We report an inexpensive cDNA dot-blot method to study expression of this gene under various environmental conditions. We observed that cold and, to a lesser extent, heat stress downregulated its expression. This information will help to understand cellulose deposition in plant cell wall under stressful conditions. To the best of our knowledge this is the first characterization of a cDNA sequence from Paulownia elongata.

“…The second possible sequestration benefit uses forest fibre (bioenergy wood) as a substitute for fossil fuels. Carbon is offset by preventing emissions from the combustion of fossil fuels that would otherwise have been used (Baral and Guha 2004). This prevention requires the specific use of harvested fibre to displace carbon emissions from fossil fuels.…”

“…This prevention requires the specific use of harvested fibre to displace carbon emissions from fossil fuels. Usually, these two scenarios have been considered as alternative strategies (Baral and Guha 2004), mostly due to different timings of CO 2 emissions. However, when occurring at the same location, they can be combined under two conditions: (1) woody biomass is used solely for energy production, and (2) IPCC rules (IPCC 2003) are used to track carbon emissions in harvested forest products to avoid double counting.…”

The economic attractiveness of Short Rotation Coppice biomass plantations for bioenergy in Northern Ontario

With an apparent abundance of idled and under-utilized agricultural land in Northern Ontario, there is interest in the ability of short-rotation forests to supply bioenergy and other possible bioproducts. Once established, Short Rotation Coppice (SRC) plantations can be harvested on (roughly) three-year cutting cycles until about age 22. Purpose-grown plantations such as these could be used as stand-alone sources of fibre or used in conjunction with sources such as natural forests or woody residues. Using a recently developed land cover model we found that approximately 405 500 ha of agricultural-type land exists across Northern Ontario. Numerous scenarios were developed to calculate SRC profitability on these areas. The analyses are intended to reflect a broad range of expectations on physical yields and prices, including management costs. Although SRC involves a considerable up-front investment, our simulations suggest a significant amount of land could have a break-even biomass price of $85/oven-dried tonnes (ODT) (+/-$5/ODT) at farm gate. This farm gate biomass price represents roughly current traditional biomass prices paid. Thus SRC would need to produce biomass at a comparable cost to be a competitive option. A number of technological and price changes could increase the attractiveness of SRC systems in Northern Ontario, including decreases in establishment and management costs (while maintaining yield expectations) and improved cultivars offering increased yields.
