Abstract/Contents: | "When assessing the potential for gene flow from transgenic plants at the landscape level, it is important to consider all the ways the genes can move. Creeping bentgrass (Agrostis stolonifer L.) is a perennial turfgrass species that can establish outside of cultivation, especially close to water sources such as irrigation ditches and canals. As part of our study of gene flow from transgenic glyphosate-resistant creeping bentgrass, we analyzed how immersion of panicles in water could affect germination of creeping bentgrass seed. We evaluated under laboratory conditions the effect of the time that the panicles spent in water and water temperature on seed germination using panicles collected from non-transgenic creeping bentgrass seed production fields. Panicles were kept in water at 20 and 4 C and removed at 0, 1, 2, 4, 6, 8, 12, and 17 weeks. Panicles were dried, threshed and seed germination tests with five replicates were conducted. We found an interaction between time in water and water temperature on seed germination. The average germination at 0 weeks was 92.7%. Although panicles that were in water at 20 C for 17 weeks had an average seed germination of 88.2%, seeds from panicles that were in water at 4 C for 17 weeks had a greatly reduced germination of 46.1%. These results show that a seed from a panicle that falls into a waterway has a good potential for establishing a seedling, even after 17 weeks of being in the water at low temperatures." |
