Enhancing Germination of Carex Pensylvanica Seed

McGinnis, E. E. and Meyer, M. H. HortScience 42(4):930. 2007.

Carex pensylvanica is a native woodland sedge that has good potential as a groundcover and alternative lawn. Low seed set combined with poor germination has limited its horticultural use. Mechanical and physiological dormancy along with unfilled achenes are all obstacles to germination. Three experiments were conducted to enhance C. pensylvanica germination. In the first experiment, the effect of perigynia removal and the presence of light was tested. The second experiment examined whether one, two or four months of after-ripening and gibberellic acid could overcome physiological dormancy. In the final experiment, seeds were exposed to three different germination temperatures.
