PEUPLIER

Les peupliers sont des arbres du genre Populus de la famille des Salicacées.

Le genre populus englobe 35 espèces des régions tempérées et froides de l'hémisphère nord. Il comprend aussi de nombreux hybrides naturels ou créés par l'homme. Les peupliers, arbres à la croissance rapide se rencontrent rarement en forêt dense mais plutôt dans les ripisylves et aux abords des zones humides où comme les saules, ils sont appréciés des castors. Ils croissent sur les terrains humides voire temporairement inondés. Leur système racinaire, important, souvent superficiel et traçant (comme celui du peuplier d'Italie par exemple) peut détruire des murs, soulever les enrobés bitumés et coloniser des tuyaux d'égouts. Certaines espèces (peuplier tremble) peuvent pousser sur des sols sableux pauvres et supportent relativement bien les embruns marins, à une certaine distance de la mer toutefois.

En dehors des espèces spontanées, de nombreuses variétés ou cultivars sont à la disposition des sylviculteurs (populiculteurs). Le séquençage du génome du peuplier a été annoncé en 2004 et publié en 2006. Le peuplier est l'essence qui a fait l'objet du plus grand nombre d'essais et de test d'arbres génétiquement modifiés (une souche en France, par l'INRA et d'autres au Canada).

I received my first <a href="http://goodfinance-blog.com/topics/business-loans">business loans</a> when I was not very old and that aided my family very much. But, I need the car loan over again.
