Abstract

Populus species are commercially important forest trees worldwide. Their practical utilization ranges from the production of quality timbers, veneer and particle board, through their use for paper and pulp production and even for non-quality application of fire wood (Olsen, 1988). As such, Populus species and hybrids are one of the major economically planted forest tree species in Europe and North America. They are also found extensively in China and India, where they have a great economical potential as a source for firewood and other applications, as well as in other countries (Zsuffa, 1985). Several Populus species were also found highly suitable for reforestation in mixed forests due to their ecological adaptation, their ability to develop a branched and efficient root system, their fast growth rate and their adaptation to tangled forest structure. Several true poplar species show high adaptability and grow well on marginal soils, and their natural shoot regeneration ability impart them an advantage in soil-conservation plantations.
