Abstract:
... Two hybrid poplar maternal half-sib families, resulting from controlled crosses of the female parent Populus deltoides 'S9-2' with P. nigra 'Ghoy' and P. trichocarpa 'V24', were grown at three sites: northern Italy, central France and southern England. Juvenile stem growth traits (height, circumference and volume) and sylleptic branchiness (number of branches, density of branches per unit of stem ...

Abstract:
... Few experiments have yet been performed to explore the potential ecological impacts of genetic modification in long-lifespan species such as trees. In this paper, we review the available data on GM trees with modified lignin focussing on the results of the first long-term field trials of such trees. These trials evaluated poplars expressing antisense transgenes to reduce the expression of the lign ...
