Climate change is one of the future challenges of agriculture that the first sign is changes in temperature. In order to elevated the resistance of maize plants to temperature changes through inoculation with three species of mycorrhiza a factorial experiment was performed in completely randomized design in research laboratory of university of Damghan. The factors were included mycorrhiza species (Acaulospora longula, Glomus moseae, Glomus claroideum, and no inoculation with mycorrhiza) and temperature (10˚, 25˚, and 40˚C). In order to temperature stress, the plants were placed in the growth chamber after 3 weeks growth in 25˚ C. The results showed that temperature stress (10˚, 40˚C) was caused to decrease the fresh and dry weight of plants, leaf and plumule length, content of chlorophyll a, b, and total. This decreasing in inoculated plants was lower than no inoculated plants. The mycorrhiza species were followed increase the carotenoid content. The highest of carotenoid content was observed in inoculated plants with G. moseae. Temperature stress, inoculate with mycorrhiza were caused the increase and decrease of Antocyanine, respectively. In addition to, temperature stress was decreased the flavonoids, that this decreasing was lower in inoculated plants. H2O2 and MDA were increased under temperature stress. The species of G. moseae, G. claroideum in decrease of H2O2 and MDA were more successful than A. longula. Phenolic compounds of maize plants inoculated with mycorrhiza 17-23% have decreased as compared to control plants.
