Flowering phenology of populus nigra l., populus nigra cv. italica and p. w canadensis moench. And the potential for natural hybridisation in Belgium

The presence of hybrid and exotic poplar plantations is considered to pose a severe potential threat to the native populations of Populus nigra in Western Europe. To evaluate the potential risks associated with the use of exotic or hybrid poplar plantations, particularly plantations of P. canadensis and P. nigra cv. italica [ P. nigra var. italica ] (Lombardy poplar), in the surroundings of natural P. nigra stands, the flower biology of a collection of P. nigra , P. canadensis and P. nigra cv. italica, was assessed. The results of this study showed that, in this stand and over the two years of... Mehr ...
