application of mycorrhizal fungi (glomus mosseae) on reducing of salinity effect in new guinea impatiens

to evaluate the effect of arbuscular mycorrhiza (glomus mosseae) under salt stress on physiological and some nutrient absorption in new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with three replications (three pots for each replication) in greenhouse in shahrekord university in 2014. treatments were inoculation of substrate with three levels of arbuscular mycorrhiza (0, 8 and 16 percent, v/v) and sodium chloride (0, 15 and 30 mm). the substrate medium was included 50 percecnt of peat moss, 40 percent of perlite and 10 percent of rice husk (v/v). the mycorrhizal inoculation done with transplanting and salt stress treatment was applied with irrigation water after stablishment of transplants. some traits such as nitrogen, phosphorous, potassium, sodium and proline content, dry and fresh root weight and root colonization percentage were evaluated. the results showed that 16 percent of mycorrhiza treatment had significant effect on nitrogen (2.31 percent) and phosphorous (0.339 percent) and it’s interaction with 30 mm of salt stress had significant effect on proline content (0.754 micromol/gfw) and root colonization (35 percent) percentage. based on this research the difference between mycorrhiza treated plants and other treatments was significant and it seems that the application of mycorrhiza in medium, can increase salt tolerance in new guinea impatiens by effect on some physiological traits.
