To evaluate the effect of density on plant growth initially Alnus glutinosa
seeds were collected from a single tree.
Material and methods: The cytotoxic ability of Alnus glutinosa
leaves ethyl acetate extract was studied over HeLa and PC-3 cell lines, with the MTT colorimetric assay.

Alders are hardly indicators because they grow practically in stream beds, but one particular species, Alnus glutinosa
, indicates a lively underground stream.
, Alnus incana, and Betula pendula, also ruderal strategists, are present in the floodplains as scattered small populations because of less competitivity with Salix and Populus species.
The restoration of alluvial forests will result in the spread of tree and shrub species such as Alnus glutinosa
, Fraxinus excelsior and Salix eleagnos.
excelsior were dominant species in the tree layer mixed with Alnus glutinosa
Extracts from Alnus glutinosa
(stem bark and leaves), Carpinus betulus (leaves and stem bark), Castanea sativa (stem bark), Ilex aquifolium (leaves), Larix decidua (leaves), Quercus petraea (stem bark) and Quercus robur (leaves) showed for the first time potent in vitro growth inhibitory activity (Frederich et al.
The trees that I am referring to include Betula pendula, our native silver birch, Betula utilis 'Jacquemontii', the Himalayan birch with white peeling bark, Corylus avellana 'Contorta', the corkscrew hazel with its strange twisted and distorted stems and Alnus glutinosa
, the native alder.
MOR and MOE values of Pterocarya fraxinifolia LVLs are higher than those of Populus euramericana, Populus tremula, Populus nigra, and similar to those of Alnus glutinosa
Species closely related to our red alder include Alnus glutinosa
, which is know by the trade name common alder.
Tannin deposits are present in infected root hairs of Alnus glutinosa
(Lalonde, 1980), and moderately electron-dense deposits occur in infected root hairs of A.

and Fraxinusexcelsior (Alno-Padion, Alnion incanae, Salicion albae).

Around the 'graus', waterways between the sea and the lagoons, areas of plantation include Tamarix gallica, Salix, Alnus glutinosa
, Fraxinus oxyphilla, Ulmus, Populus alba and Platanus.
