| Abstract/Contents: | "Cheatgrass (Bromus tectorum L.) is an undesirable nonnative annual that germinates at relatively low temperatures in the spring and fall and can establish a root system more quickly than Great Basin native perennial grasses. The purpose of this study was to determine whether seed priming could be used to enhance low-temperature germination rate of native perennial grasses so that they can better compete with cheatgrass. A matric-priming technique was used to increase low-temperature germination rate of seven native perennial grasses: blue-bunch wheatgrass [Pseudoroegneria spicata (Pursh) Love], thickspike wheatgrass [Elymus lanceolatus (Scribn. & J.G. Smith) Gould; syn. Agropyron dasystachyum (Hook.) Scribn.], basin wildrye [Leymus cinereus (Scribn. and Merr.) A. Love], sheep fescue (Festuca ovina L.), canby bluegrass (Poa canbyi Scribn.), sandberg bluegrass (Poa sandbergii Vasey), and bottlebrush squirreltail [Sitanion hystrix (Nutt.) J.G. Smith]. Seeds primed at both 10 and 25 [degrees celcius (C)] were evaluated for germination response at both 10 and 25 C. Days to 50% germination (D50) was [approximately] 4 d for cheatgrass germinated at 10 [degrees]C. Native grass seeds in control treatments germinated between about 4 and 11 d later than cheatgrass at 10 C. Priming reduced D50 by between 4 and 8 d for all native species when germinated at 10 C. Germination rate at 10 C was generally higher when the seeds were primed at 25 C, except for basin wildrye. Priming increased cold temperature germination rate of bluebunch wheatgrass, thickspike wheatgrass, and sheep fescue to a level comparable to cheatgrass." |
