Understanding the behavior of arbuscular mycorrhizal fungi (AMF) associated with plants is essential for optimizing plant cultivation to the phytoremediation of degraded soils. The objective of the present study was to evaluate the differences in AMF root colonization between novel seed-based interspecific hybrids ( × ) and the standard × when grown in soils contaminated with heavy metals (Pb, Cd, and Zn). During the third and fourth growing seasons, higher concentration of metals in the roots and a limited transfer of metals from the roots to the shoots were observed in all the plants studied. After the third growing season, the lowest values of AMF colonization rates were observed for the hybrid. After the fourth growing season, AMF colonization decreased, which could be due to the drought that occurred during that season. showed a lower tendency to develop mycorrhizal structures on heavy-metal (HM)-contaminated soils than and ; however, this hybrid was insensitive to changes in colonization rates during the dry growing season.
了解与植物相关的丛枝菌根真菌（AMF）的行为对于优化植物种植以实现退化土壤的植物修复至关重要。本研究的目的是评估新型种子间种杂交种（×）和标准×在重金属（铅、镉和锌）污染土壤中生长时，AMF根系定殖的差异。在第三和第四个生长季节，在所研究的所有植物中均观察到根系中金属浓度较高，且金属从根系向地上部分的转移有限。在第三个生长季节后，杂交种的AMF定殖率最低。在第四个生长季节后，AMF定殖率下降，这可能是由于该季节发生的干旱所致。与和相比，在重金属（HM）污染土壤上形成菌根结构的趋势较低；然而，该杂交种在干旱生长季节对定殖率的变化不敏感。
