A t-test was used to compare survival of Polygonum aviculare in the low and high salinity plots at the end of the growing season (Jandel Scientific Software, 1992).
Soil samples were wet-sieved through a 1-mm sieve to determine if Polygonum aviculare achenes were present.
Polygonum aviculare plants were collected from the field site on 18 September 1994 and allowed to dry at room temperature for 6 days before removing the achenes.
A linear regression indicated a good relationship between Polygonum aviculare survival and soil electrical conductivity ([r.
Germination of Polygonum aviculare achenes was significantly different (F = 16.
Density of Polygonum aviculare plants decreased 55% in the high salt environment from June to September 1994, and there was greater mortality in the high than in the low salinity plots.
Our results with Polygonum aviculare are consistent with Paalvast (1978), since salinity stress was the primary factor inhibiting growth and an increase in density did not cause a concomitant decrease in yield.
