Table 1: Complete list of plant species, along with associated taxonomic families, broad functional groups, and life histories used in the seed germination experiment

Note: These species are commonly used in restoration seedings in grasslands of central North America. This experiment was conducted 1 year following the conclusion of the field experiment conducted by Robertson et al. (2013), and was conducted at greenhouse facilities at Oklahoma State University in Stillwater, OK, USA. Abbreviation: SL, short-lived.

Table 2: Relative germination of 16 native species commonly used in restoration seedings in grasslands of central North America (see Table 1 for complete species names)

Note: Values represent percent differences in germination relative to native prairie soils (control). Seeds were sown into the following soil treatments: (1) native prairie (control [data not shown]), (2) dominated by Bothriochloa ischaemum (Bi), (3) dominated by B. ischaemum with native prairie soil amendment (Bi, amended), (4) dominated by B. ischaemum and treated with various combinations of herbicide and prescribed fire (Treated), and (5) dominated by B. ischaemum and treated with various combinations of herbicide and prescribed fire with native prairie soil amendment (Treated, amended). 

*Significant reductions in germination (%) compared to seeds sown in native prairie soils, with significance assessed at p ≤ 0.05.

Figure 1: Relative germination of (a) warm-season grasses, (b) cool-season grasses, and (c) forbs when sown in soils collected from areas dominated by: Bi, Bothriochloa ischaemum; Bi+A, B. ischaemum amended with native prairie soil; Tr, B. ischaemum treated with various combinations of herbicide and prescribed fire; and Tr+A, B. ischaemum treated with various combinations of herbicides and prescribed fire amended with native prairie soil. Bars represent the relative differences in germination (%) from the native soil control (±SE). *Significant reductions in germination (%) compared to seeds sown in native prairie soils. Bars with different letters indicate significant differences among soil sources, with significance assessed at p ≤ 0.05.
