Effect of Arbuscular Mycorrhiza (Glomus etunicatum) on some physiological growth parameters of tomato plant under copper toxicity in solution.
In this study, the effect of the Arbuscular Mycorrhizal fungus Glomus etunicatum on the physiological growth parameters of tomato (Lycopersycium esculentum Mill) plants on the toxicity level of copper was investigated. To explain the physiological growth of these plants, some physiological growth parameters were determined in the shoots and leaves of Arbuscular Mycorrhizal (AM) and non-mycorrhizal (non-AM) plants such as Dry Matter (DM) contents, chlorophyll (chl) content and amount of total sugar. All parameters increased in AM tomato plants compared with those of the non-AM plants. Furthermore, it was determined that P concentration was positively correlated with all chlorophyll and sugar contents. It is concluded that increased P concentration because of the mycorrhizal symbioses, positively affects the physiological performance of tomato plants.
