Deployment of Tree Resistance to insects in Short Rotation Biomass Plantations
نویسنده
چکیده
Short rotation woody crop (SRWC) plantations use fast-growing tree species (such as Populus and Salix) grown under intensively managed conditions much like traditional agricultural crops (Dickmann and Stuart 1983). Typical rotation age ranges from 3-15 years, with the end products including energy and paper (pulp) products. Operational biomass plantations currently use a limited number of clones that probably exhibit modest host plant resistance to insects and may be promoting insect adaptation to resistance. Current control methods include clonal rotation and pesticide use (Abrahamson et al. 1977). There is a need to find and implement more effective insect resistance mechanisms and clonal deployment strategies into SRWC plantations.

Performance of poplar (populus deltoides bartr.) and its effect on wheat yield under agroforestry system in irrigated agro-ecosystem, India
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
متن کاملHarvesting Short-Rotation Poplar Plantations for Biomass Production
Nacrtak In Italy, short rotation forest has become very popular in recent years, with over 4,000 hectares already planted – almost exclusively with clone poplar. The study models the performance of modified forage harvesters on a range of short-rotation poplar plantations, identifies technical obstacles to the deployment of these machines and suggests solutions that may expand the capability of...
متن کاملComparison of allometric equations to estimate the above-ground biomass of Populusalba species (Case study; poplar plantations in Chaharmahal and Bakhtiari province, Iran)
Carbon sequestration into plants biomass, especially in fast growing trees is an easier and economically way for dropping off CO2 from atmosphere. This study was carried out in order to investigate above-ground biomass of white poplar (populous alba, L.) plantations that was planted in fourdifferent plant spacing (0.5 × 0.5, 1×1, 2×2 and 4×4 m.) in Chaharmahal and Bakhtiari province in west of ...

Background and Purpose: Most projections of the global energy use predict that biomass will be an important component of primary energy sources in the coming decades. Short rotation plantations have the potential to become an important source of renewable energy in Europe because of the high biomass yields, a good combustion quality as solid fuel, ecological advantages and comparatively low bio...
