- Polygonum aviculare occurred on the border of a brine spill in southeastern Ohio, which indicates that this population is capable of tolerating at least some level of soil salinity.
A regression analysis was used to determine the relationship between the survival of Polygonum aviculare and soil conductivity (mS/cm) at the end of the 1994 growing season (Sokal and Rohlf, 1995).
Within one set of 10 plots, spontaneously growing Polygonum aviculare plants were thinned to a density of one plant, while in the other 10 plots the plants were thinned to a density of 10 plants.
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.sup.2] 0.316, P = 0.0058) at the end of the growing season [ILLUSTRATION FOR FIGURE 4 OMITTED].
- Germination of Polygonum aviculare achenes was significantly different (F = 16.5, df = 3, P [less than] 0.0001) among the four salinity treatments, and among the four thermoperiods (F = 37.4, df = 3, P [less than] 0.0001).
Polygonum aviculare plants had lower densities in the high salinity plots than in low salinity plots.
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.
