Heavy metals (HMs) or/and polycyclic aromatic hydrocarbons (PAHs) stress have significant adverse effects on the photosynthetic function and SPAD values of plants. Physiological integration is typical feature clonal plants, which can mitigate ramets under heterogeneous stress. However, sustainability physiological between clones over prolonged durations, dynamics intensity potential differences various types remain unclear. This study examined three different stresses—cadmium (Cd), phenanthrene (Phe), a combination Cd Phe (Cd + Phe) Zoysia japonica at time points. The results indicate that significantly enhances value, net rate (PN), stomatal conductance (Cond), intercellular CO₂ concentration (Ci), transpiration (Tr), water use efficiency (WUE). diminishes with exposure. In addition, among types, initial was highest toxicity conditions, it decreased most rapidly, resulting in lowest during later stages To sum up, this highlights role maintaining plants elucidates temporal changes conditions.
