The present study aimed to examine the interactions of mycorrhiza and air pollutant and acid rain on indicators such as chlorophyll, protein and carotenoids, as well as on maize (Zea mays) in a completely randomized design with 10 replications and in greenhouse conditions from February 2016 to April 2017. Experimental variants were classified in four groups including maize (Zea mays) colonized with Glomus etonicatum irrigated with acid rain water and normal water with pH=7 and control plants irrigated with acid rain water and normal water.
Results from analysis of variance (by SPSS software) revealved that the effect of mycorrhizal inoculation on indicators such as the height of plant, the number of leaves, fresh leaf weight, dry leaf weight, root weight, the number of fruits, the amount of chlorophyll a, b, total chlorophyll, carotenoids and protein, were significant (p<0.05). Inoculation with Glomus etonicatum caused a significant increase in the mentioned indicators compared to the control ones. The highest amount was observed in plants inoculated with mycorrhiza and irrigated with normal water and the lowest amount was observed in control plants irrigated with acid rain water. Further, the results indicated that even the amount of these indicators in mycorrhiza plants irrigated with acidic water was significantly higher than that of the control plants irrigated with normal water. In general, inoculation with Glomus etonicatum could increase the growth and photosynthesis of plants, even under acid rain and air pollution, compared with non-mycorrhiza plants and in normal condition.
