Abstract
Examines the allelopathic effects of Andropogon virginicus on native species in Oklahoma, including Schizachyrium scoparium (syn. Andropogon scoparius). Aqueous extracts of fresh roots and shoots of A. virginicus inhibited the growth of S. scoparium. Extracts of roots and shoots of A. virginicus were also inhibitory to two test species of Azotobacter, a free living nitrogen fixer, and to two species of Rhizobium, a symbiotic nitrogen fixer. Andropogon virginicus is known to compete vigorously and grow well on soils of low fertility. This demonstrated allelopathy could help explain why stands of A. virginicus remain in old fields for long periods of time.Suggested Citation
