Grass is one of the best cover plants that have long been known and is now one of the main and landscape designer is an integral part. By which we can change the face of the earth dry and lifeless expanse of green And fresh replace the soil. Because only part of the north of the country, other areas are areas in these regions due to deficiency of rainfall in heaven, Overuse of groundwater and saltwater intrusion into aquifers mantle sweet and management of irrigation leads to salinization of soils is bad. Considering the above limitations, salt tolerance study examined 10 varieties of grass Poa (Poapratensis), (Poapratensis), including “Ampellia”, “Park”, “Harmony”, “Merion”, “Crusade”, “Nutop”, “Balin”, “Challanger”, “Genome”, and “Banf” factorial completely randomized design With three replications and six levels of salinity (0.3, 1.5, 3, 4.5, 6, 7.5) DS m was conducted on a farm located in Izeh. The results of analysis of variance showed that the effect of cultivars, salinity and their interactions More on the index measuring the level of one percent difference is significant. Maximum chlorine aerial part of the “Crusade” and the least amount of chlorine aviation sector is also related to the “Harmony” was. Decimal study shows the correlation between the traits that increase the amount of proline in leaves, grass quality, shoot dry weight, root dry weight and water content of leaves significantly reduced And also increased the percentage of burns grass. The more sensitive data such production has been more proline. The results of analysis of variance showed that the effect of cultivars, salinity and their interaction on the measured indices Have a significantly different level. Maximum chlorine aerial part of the “Crusade” was And shoot the lowest amount of chlorine is also related to the “Harmony” was. Decimal study shows the correlation between the traits that increase the amount of proline in leaves, grass quality, shoot dry weight, The results of analysis of variance showed that the effect of cultivars, salinity and their interaction on the measured indices Have a significantly different level. Maximum chlorine aerial part of the “Crusade” and the least amount of chlorine aviation sector is also related to the “Harmony” was. Decimal study shows the correlation between the traits that increase the amount of proline in leaves, grass quality, shoot dry weight, root dry weight and water content of leaves significantly reduced And also increased the percentage of burns grass. Proline production was higher than in susceptible cultivars of this species that could possibly.
