D. GOTTLIEB Puccinellia x phryganodes (Trin.) Scriber and Merr is widely distributed in Arctic salt marshes. In North America the species, which is capable of extensive clonal growth, appears to be a sterile triploid (2n = 21) ; seed set has never been observed. Consequently it was predicted that the level of genetic variation would be low, both within and between populations. Examination of electrophoretic mobilities of isozymes of 12 enzyme systems in plants from three widely separated populations in Arctic Canada indicated a high level of variability both within and between the populations. The unexpected discovery of significant amounts of genetic variability suggests that sexual processes occur in this species. 2013-04-07T00:00:00Z http://hdl.handle.net/10315/20599 My Life with Grass Bazely, Dawn 2011-08-26T00:00:00Z http://hdl.handle.net/10315/20598 Lorenzo Cohen's keynote talk at Bob Jefferies' Symposium Cohen, Lorenzo keynote talk 2011-08-25T00:00:00Z http://hdl.handle.net/10315/20597 Fred Cooke's keynote talk at Bob Jefferies' Symposium Cooke, Fred; Bazely, Dawn Welcome and keynote talk 2011-08-25T00:00:00Z
