“…Contrary to this, accessions 237186, 237131 and variety DZ-Cr-37 that were the most salt tolerant genotypes in terms of final germination percentage (FGP) and germination rate (GR) showed promising seedling growth. It has already been reported that plant growth and development is dependent on crop stand establishment (Verma and Yadava, 1986), in turn the latter is a function of effective germination (Horst and Taylor, 1983) and seedling growth (Ashraf and Wheed, 1992). Crops with higher germination percentage and low germination rate can establish themselves effectively on moderately saline soils (with 2dS/m -10dS/m electrical conductivity) (Lee et al, 1998).…”

Salinity is a continuing problem in the arid and semi-arid tracts of the world. It could be alleviated using irrigation management and/or crop management. However, the former approach is outdated and very expensive. Nevertheless, the latter is economical as well as efficient, and it enables to produce salt tolerant crop lines. But prior to that there is a need to confirm the presence of genetic based variation for salt tolerance among different species or varieties of a particular crop that can thrive under unreliable agro-ecological situations; tef [Eragrostis tef (Zucc) Trotter] is one of such crops. Thus fifteen lowland tef genotypes (10 accessions and 5 varieties) were tested during germination and seedling stage at 2dS/m, 4dS/m, 8dS/m, 12dS/m and 16dS/m salinity levels. Distilled water (0dS/m) was used as a control. Data analysis was carried out using SAS package. Germination percentage (GP), germination rate (GR), seedling shoot length (SSL) and seedling root length (SRL) were measured. The analyzed data showed significant variation among most parameters recorded for accessions and varieties (p < 0.01) and for treatments (p < 0.001). Germination rate and seedling root length were more salt affected than final germination percentage and seedling shoot length respectively. The main cause for reduced and delayed germination percentage was osmotic effect. The ion effect was also learned to be minimal. Most accessions and varieties failed to germinate at 12dS/m and 16dS/m salinity levels. Thus, these salt concentrations were not important in screening tef genotypes for salt tolerance. Varieties such as DZ-01-1281, DZ-Cr-358 and accession 236512 were found to be salt sensitive. However, variety DZ-Cr-37 and accessions 237186, 237131 and 212928 were found to be salt tolerant. The rest accessions and varieties were intermediate in their salt tolerance. The study affirmed the presence of broad intraspecific variation among tef accessions and varieties for salt tolerance but more in the former.

The need for salt-tolerant turfgrasses is ever-increasing. Rapid urban population growth has put enormous pressures on limited freshwater supplies. Many state and local governments have reacted by placing restrictions on the use of potable water for irrigating turfgrass landscapes, instead requiring use of reclaimed, or other secondary saline water sources. In coastal areas, overpumping, and resultant salt water intrusion of coastal wells used for irrigating turfgrass facilities has widely occurred. The nature and extent of the salinity problem, followed by basic salinity issues and available management choices, will be discussed. Issues facing the turf manager using saline water sources are soil salinization, resulting in direct salt injury to turf, and secondary problems of loss of soil structure ensuing from sodium and bicarbonate effects, resulting in loss of salt leaching potential and soil anaerobiosis. Management choices for the turf manager using saline water are limited. Soil salinity must be maintained below the level deemed detrimental to the turf, by maintaining sufficient leaching. Sodium/bicarbonate affected soils must be managed to maintain sufficient permeability to permit adequate leaching. Finally, salt tolerant turf species/cultivars must be used. Long-term solutions to the salinity problem will require development of improved salt-tolerant turfgrasses. Progress in cultivar development, and future development of potential alternative halophytic turfgrass species will also be discussed. Media summaryRapid urbanization has resulted in escalating salinity issues facing turfgrass landscapes. The extent of the salinity problem, salinity management issues, including soil salt-leaching and sodicity-permeability management, use of salt tolerant turf cultivars, and future development of salt tolerant turfgrasses will be discussed.

“…Dai et al (2009) also compared salinity tolerance of greens-type P. annua. Germination rate and seedling growth (blade length and tissue weight) of perennial ryegrass, kentucky bluegrass, and tall fescue cultivars under saline conditions were evaluated in hydroponic systems (Horst and Beadle, 1984;Horst and Dunning, 1989;Horst and Taylor, 1983). Similar trends were observed that seed germination and seedling growth are reduced as saline stress severity increases.…”

The effect of salinity on germination factors was evaluated for twenty five genotypes as the parents and first generation synthetic progenies (Syn1) of tall fescue. To produce polycross seeds, four groups of six parental plants with contrasting levels of diversity based on phenotypic traits and contrasting levels of AFLP molecular marker diversity constructed. An experimental factorial, in a randomized complete block design was conducted under five salinity levels (0, 50, 100, 150, 200 mM NaCl). In each experiment 10 ml from salt solution was added to each Petri dish. Seeds were allowed to germinate at 25 ± 1°C for 14 days. Daily, final germination and emergence percentage, as well as germination and seedling emergence rate, and seedling fresh and dry weight were measured in the study under controlled and stress conditions in parental genotypes and also first generation progenies. The results showed that the differences between parents of populations were not significant for the evaluated traits but the effect of population in progenies were significant for all of the evaluated traits. It seems that the polycrosses of the parental genotypes gathered the positive genes in progenies and caused the significant increases in the evaluated traits such as germination percent, germination rate, fresh weight of leaf and radical length. HMD and LMD populations had the highest means for most of the evaluated traits such as germination percentage and germination rate in all stress and non-stress conditions. The parents of these population selected based on molecular markers diversities. The correlation between similarity matrix of parents based on molecular markers and the similarity matrix of first generation of progenies based on morphological traits was significant (r=0.35). The highest broad sense heritability was observed for fresh weight of radical in parents and progenies (70% and 80%), while the lowest was observed for radical length in both parents and progenies (13% and 15%). Our results demonstrate that molecular markers can be reliable tools to efficiently selecting parental genotypes and improving tall fescue breeding programs.
