Evaluation location: Iowa, United States
Seed images obtained using Adobe Photoshop CS4 with Silver Fast 6.0 (Plustek OpticPro A320) set at 300 DPI with diameter measurements captured using SmartGrain v.1.1 (Tanabata et al. 2012). Random sample of 10, intact seeds. Measurements in millimeters. Diameter defined as the widest distance through the medial portion of the seed, which is typically from the hilum to the distal portion. In general, Gymnocladus dioicus seeds are near perfectly round, but often slightly longer in length by usually 1 mm or less. Reference: Tanabata T, Yamada T, Shimizu Y, Kanekatsu M, Takano M. 2012.
