Todd is listed as a plum cultivar, rendered as Prunus spp. 'Todd', in a University of Minnesota document focused on plum seed germination and seedling performance [S1].
In Experiment II, Todd had 75.0% germination in both non-scarified and scarified treatments. The non-scarified value was the highest cited in the experiment range, with a mean of 1.1 weeks for non-scarified seed and 1.6 weeks for scarified seed [S1].
In Experiment III, field seedlings from Todd had the highest cited initial stem diameter, 2.39 mm, and were reported as differing significantly from a number of other plum cultivars in that comparison. Reported survival at the end of the experiment was 85% in the greenhouse and 97% in the field [S1].
Todd seedlings also had a herbivore damage rating of 4.8, the highest cited on the page, and produced one or more root suckers in the greenhouse trial; the field sucker count was reported as zero [S1].
Summary source basis
This summary currently draws chiefly from Minnesota #1695.
