Common garden comparison between allopolyploid Salsola ryanii and its progenitors S. tragus and S. australis

We conducted a common garden comparison over two years to determine how different fitness correlates (plant volume, plant mass and estimated seed number) of the newly formed allopolyploid species Salsola ryanii compares to its progenitors (Salsola tragus and S. australis) at a site within the range of all the newly formed allopolyploid and both of its progenitors.
