Popis: There is a need to develop effective techniques for establishing native vegetation in dryland ecosystems. We developed a novel treatment that primes seeds in a matrix of absorbent materials and bio-stimulants and then forms the mixture into pods for planting. In the development process, we determined optimal conditions for priming seeds and then compared seedling emergence from non-treated seeds, non-primed-seed pods, and primed-seed pods. Emergence trials were conducted on soils collected from a hillslope and ridgetop location on the Kaibab Plateau, Arizona, USAPoa fendlerianaandPseudoroegneria spicatawere used as test species. Seeds were primed from −0.5 to −2.5 MPa for up to 12 d. Seeds primed under drier conditions (−1.5 to −2.5 MPa) tended to have quicker germination. Days to 50% emergence for primed-seed pods was between 66.2 to 82.4% faster (5.2 to 14.5 d fewer) than non-treated seeds. Seedling emergence from primed-seed pods forP. fendlerianawas 3.8-fold higher than non-treated seeds on the ridgetop soil, but no difference was found on the other soil. Final density ofP. spicataprimed-seed pods were 2.9 to 3.8-fold higher than non-treated seeds. Overall, primed-seed pods show promise for enhancing germination and seedling emergence, which could aid in native plant establishment.
