| Abstract/Contents: | "Studies are underway at Colorado State University to develop tyrf-type inland saltgrass [Distichlis spicata var. stricta (L.) Greene] cultivars for targeted use in the regions where soil and water salinity are high. With such an effort, it is important to understand the genetic variability of salt tolerance of inland saltgrass selections. This study's findings include: Following one-month exposure to 12 mmho/cm salinity in hydroponic culture, five selections exhibited acceptable turf quality (quality rating >6.0). COAZ-01, COAZ-17, COAZ-18, COAZ-02, and COAZ-22 had better quality that other selctions. Relative leaf firing range was 0-20%, 0-32%, 5-35%, and 8-36% after one month at 12, 24, 36, and 48 mmho/cm salinity growth solutions, respectively. Selections COAZ-01, COAZ-18, COAZ-02, COAZ-22, COAZ-08, and CO-01 show less leaf firing than other lines at 48 mmho/cm salinity. Root activity (viability) increased as salinity increased from 2 mmho/cm to 36 mmho/cm. As salinity increased further, root viability decreased. COAZ-18 and COAZ-19 exhibited the highest root activity among all experimental lines. Based on the number of times in the best statistical category for turf quality, leaf firing, root growth, and root viability in this experiment, selections COAZ-18 and COAZ-01, and COAZ-22 have superior salt tolerance." |
