Alderman is a University of Minnesota plum hybrid listed under Prunus spp. It was released in 1985, with Brooks and Olmo 1997 cited for the release date [S1].
In one University of Minnesota experiment, Alderman had low non-scarified seed germination: 4.2%, the lowest average reported in that greenhouse set. Scarified seed germination was reported as 37.5%, with a significant difference between scarified and non-scarified seed [S1].
Other trial data list Alderman with 70% greenhouse survival and 100% field survival at the end of Experiment III. A table row also reports initial height of 19.1 cm, initial stem diameter of 2.00 mm, stem diameter change of 2.74 mm, and ΔTCA of 16.96 mm² [S1].
Summary source basis
This summary currently draws chiefly from Minnesota #1695.
