Table 1.
Recipe for producing extruded seed pods under optimal priming conditions.
The recipe was used on 8.11 and 32.48 g of ‘Ruin canyon’ Poa fendleriana and ‘Anatone’ Pseudoroegneria spicata seed, respectively. This amount of seed was needed to produce approximately 8 pure live seed pod-1.

Moisture release curve of material used for producing extruded seed pods.
Water content is expressed as percentage based on the dry weight of the solid material. CurveExpert 1.4 was used to fit curve; best fit curve used a logistic model where a = 3.1441, b = -7.5929E-001, and c = -4.2990E-002.

Table 4.
Mean seedling emergence from Poa fendleriana and Pseudoroegneria spicata seeds which were treated and planted in two differing terrains/substrates.
Seeds were either non-treated (Control), incorporated into a pod (Pod), or incorporated into a primed-seed pod (P-Pod). Seeds were planted in either a ridgetop or hillslope soil collected from the West Side region of the Kaibab Plateau, USA.
