Provenance Material
This trial is seed based with two to five seedlots per region (provenance).
Seed collected form single mother trees which were open pollinated, therefore male component is unknown.
These seed lots are considered half sib. See figure this page for the latitude that each provenance was collected from.
All seedlots are assumed to be pure P. tremuloides and adapted to the region in which they were collected from.
