Abstract

Soil pollution with heavy metals is an important environmental problem which affects human and food health. NEOTYPHODIUM ENDOPHYTEs are a group of fungi which stay their entire life cycle within the aerial portion of many grass species without any symptoms, and increase host tolerance to biotic and abiotic stresses. In this study two genotypes of tall fescue (75B and 75C) in two types (infected (E+) and non-infected (E-) by ENDOPHYTE) were cultivated in a Ni contaminated soil at 0, 30, 90 and 180 mg Ni per kg with 3 replicates. After 2 months, Ni uptake of the root and shoot and CHLOROPHYLL and CAROTENOID content of the shoot were determined. Growth parameter including root and shoot wet weight and root to shoot weight ratio of plants also were measured at the end of the experiment. The results showed that endophytic fungi caused an increase in CHLOROPHYLL contents of the shoot in both genotype and an increase in Ni uptake only in genotype 75B. Results also demonstrated that ENDOPHYTE infection led to improvement in the growth and Ni tolerance within genotype 75B of tall fescue under Ni stress. But in the genotype 75C, in contrast, the E- plants showed more tolerance to Ni stress compared to E+ ones. It revealed that effect of ENDOPHYTE infection in Festuca plants as the host is dependent on the host genotype.
