RUIZ-SANCHEZ, Michel et al. Mycorrhizae arbuscular symbiosis in rice plants (Oryza sativa L.) under water stress. Part II Biochemical response. cultrop [online]. 2015, vol.36, n.3, pp. 88-95. ISSN 1819-4087.

It is estimated that the world population will continue to increase; however the water resources available to meet crop right now is not enough, it is working to find alternatives that save water and maintain or increase agricultural crop yields. The use of arbuscular mycorrhizal fungi (AMF) is certainly a way that contributes to such purposes. The research was conducted at the Experimental Station of Zaidín, Granada, Spain, in plastic pots with plants of mycorrhizal and non-mycorrhizal rice in semi-controlled conditions, with three water supplies, no stress (25 mL), moderate stress (10 mL) and severe stress (5 mL) for 15 days, with the aim of evaluating the effect of the inoculation of Rhizoglomus intraradices in rice plants under water stress and then retrieved on some biochemical parameters. The results showed that the symbiosis HMA reduces the accumulation of hydrogen peroxide and oxidative damage to lipids from an increased accumulation of the antioxidant glutathione. The combined effects of plant metabolism improved after a period of water stress and can be suggested as indicators under conditions of water deficit in plants mycorrhizal rice
