Abstract/Contents: | "Researchers at Arizona State University, University of Arizona, and Texas A&M are testing whether salt gland density, as a genetic trait, can be used to screen for salt-tolerant germplasm. Fifteen zoysiagrasses (Japanese lawngrass - Zoysia japonica) were tested for salinity tolerance using a solution culture-hydroponics growing system. The most salt-tolerant varieties were El Toro and Palisades, and the least tolerant were Sunrise, K162, JS-23, and K157. Salt gland densities were determined for all entries, growing under both salt-free (control) and saline conditions. Results of this study show that salt tolerance and salt gland activity is related to the actual density of salt glands on the leaves, or the number of glands per unit leaf area. Salt gland density on grasses grown in salt-free conditions predicted salinity tolerance, as well as plants grown under saline conditions. This is the first report of a morphological (visual) trait which can be used to predict salt tolerance of grasses. Salt gland density is an innate, genetically-controlled, heritable trait which does not require environmental stress conditions to express itself. Salt gland density is a much easier screening procedure which could expedite selection of salt-tolerant grasses, in that the breeder need only count salt gland density on leaves of plants growing under regular (non-salt) conditions." |
