| Abstract/Contents: | "Wildflower sod was established in a greenhouse by sowing primed or non-primed seed of two seed mixtures at 2x (2.44 g/m², 0.5 lb/1000 ft²) or 10x) 12.20 g/m², 2.5 lb/1000 ft²) the supplier's recommended field broadcast rate onto a 2.5 cm (1 in) settled depth of commercial peat-lite (ProMix BX) contained in 28 x 52 x 5 cm (11 x 20.5 x 2 in) flats. One seed mixture (NE, Northeast) contained 54% of the species as annuals, the remainder being biennial and perennial species. The other mixture (NEANN) was a 1:1 (weight) combination of NE with a 100% annual species mixture. Seeds were primed matrically in expanded, fine-grade vermiculite for four days at -0.5 MPa at 15C (59F) in darkness (vermiculite:water:seed, 5:5:1 by wgt). At five weeks after sowing, root rating (an estimate of rooting magnitude), sod stability (an estimate of resistance to sod separation), and shoot dry weights were increased as a result of sowing primed NEANN seeds at 10x. Sod netting with 2.8 cm (1.1 in) openings, whether placed at the bottom or the top of the substrate, had no effect on these variables. Sod of a duplicate, concurrent experiment was transplanted in the field at five weeks after sowing. By 12 weeks after sowing, the 10x seeding rate increased shoot dry weight, but the effect of seed priming on shoot dry weight had been lost." |
