| Abstract/Contents: | "Saltgrass [Distichlis spicata var. stricta (Greene)] has desirable turf characteristics and great potential for use as a turfgrass and as a revegetation species of saline sites. Experiments were carried out to determine the effects of saltgrass seed soaking in Proxy, and the most effective soaking time and concentration, in the enhancement of saltgrass germination under saline conditions. Germination was reduced from 42.7 % at soil EC of 4.0 dS m-1 to 27.1, 16.4 and 7.1 % at soil EC of 6, 12, and 18 dS m-1 respectively. Soaking saltgrass seeds in Proxy solution at 3.33 g/L for 48 hours increased seed germination percentage and speed under both non-saline and saline conditions. Under saline conditions, the concentration of 6.66 g/L was most effective in increasing saltgrass seed germination at soil salinity levels of 6, 12 and 18 dS m-1. Seed soaking for 48 hours was more effective in improving both saltgrass seed germination and speed than soaking for 24 hours. Regression analysis indicated a significant, negative linear relationship between the level of final soil salinity vs. germination percentage (R2 ranged from 0.74 to 0.96) and germination speed (R2 ranged from 0.73 to 0.96) at all proxy concentrations under all soaking times." |
