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.
在本研究中，调查了丛枝菌根真菌幼套球囊霉对处于铜毒性水平下的番茄（Lycopersycium esculentum Mill）植株生理生长参数的影响。为解释这些植株的生理生长情况，测定了丛枝菌根（AM）植株和非菌根（非AM）植株地上部分和叶片中的一些生理生长参数，如干物质（DM）含量、叶绿素（chl）含量和总糖量。与非AM植株相比，AM番茄植株的所有参数均有所增加。此外，还确定磷浓度与所有叶绿素和糖含量呈正相关。得出的结论是，菌根共生导致的磷浓度增加对番茄植株的生理性能产生了积极影响。
