Seed Biology Of Physaria Ludoviciana (Silvery Bladderpod; Brassicaceae ), An Endangered Species In Sand Prairies Of The Midwest, Marissa Grant, Ann Claerbout, Janice Coons, Henry Owen

Faculty Research & Creative Activity

Physaria ludoviciana (Nuttal) O'Kane & Al-Shehbaz (silvery bladderpod) is a state endangered species in Illinois, Minnesota and Wisconsin, the eastern edge of its range. Our goal was to investigate its seed biology (production, dispersal, seed bank longevity, afterripening, seed longevity after storage using germination and emergence, and seedling establishment). This information will be useful for conservation efforts of this endangered species. Over a ten-year period, various seed biology parameters were measured. Infructescences were counted to estimate seed production with 110–744 seeds per reproductive plant. Soil samples were collected at various distances to estimate dispersal where seeds dispersed less than a …
