Abstract

Forest trees in the genus Populus are utilized for timber, pulp, and components of plywood and flakeboard manufacturing, and more recently, as whole tree fuelwood for bioenergy production. The more commercially important species are from two of five sections in the genus Populus, Leuce and Aigeiros. Poplars are widely dispersed throughout the northern hemisphere and occur along waterways and bottom lands, and in colder regions of temperate climactic zones including those regions in the USA, Belgium, Canada, UK, China, India and Japan (Ahuja, 1993). As a pioneer and coppicing species, poplars adapt to a wide variety of sites and the main limitation for growth is water availability. In general, members of the genus respond remarkably to cultural inputs such as weed control, irrigation, and fertilization which result in phenomenal growth rates for biomass production (Chun, 1993). Despite the ease of hybridization between many Populus species, traits for biotic and abiotic resistances and adequate adventitious rooting are still lacking in many important commercial clones (Michler, 1993; Ostry and Michler, 1993).
