| Abstract/Contents: | Presents a study to "determine if salt gland density can be used to predict turfgrass salt tolerance, and if they can be used as an effective salt-tolerance selection tool by turfgrass breeders." Results include that "salt tolerance and salt gland activity are related to the actual density of salt glands on the leaves, or the number of glands per unit of leaf area. There is a positive correlation with both leaf salt gland density and leaf tolerance. In other words, as leaf salt gland density increases, so does salt tolerance...It was found that salt glands are not induced by salt stress, i.e., within a variety there was no difference in gland density between a plant grown in saline conditions and one grown in salt-free conditions. In other words, the grasses are 'born' with a certain density, depending on their genetics. Averaged across all genotypes and within a genotype, there was less than a 1% difference between control (non-stressed) and salt-stressed grasses, indicating a very high heritability for this trait. Salt gland density on grasses grown in salt-free conditions predicted salinity tolerance as well as [for] plants grown under saline conditions. This is the first report of a morphological (visual) trait that can be used to predict salt tolerance of grasses. Salt gland density is an innate, genetically controlled, heritable trait that does not require environmental stress conditions to express it." |
