Abstract/Contents:"Seed osmopriming was investigated as a means of improving germination performance of three herbage grasses (Festuca arundinacea Schreb. cv. Cigale, Dactylis glomerata L. cv. Lude and Bromus catharticus Vahl. cv. Samson) under four suboptimal temperatures (2, 5, 8 and 11°C). Seeds were primed in aerated solutions of polyethylene glycol 6000 (PEG) of KNO₃, or KNO₃ + K₂HPO₄ at 18± 1°C and then rinsed, and dried. Seed osmopriming, especially with salt solutions, significantly increased germination percentage of F. arundinacea and D. glomerata at 2 and 5°C, where the germination of untreated seeds was greatly reduced or inhibited. In B catharticus osmopriming was of little but significant benefit only at 2°C. Primed seeds exhibited a significant increase in germination rate of the three herbage grasses under all the germination temperatures except at 12°C for B. catharticus. This positive effect was more evident in F. arundinacea and in salt primed seeds."
