Physiological and Biochemical Adaptation of Common Garden Plants to Inorganic Nitrogen-Laden Fine Particulate Matter Stress

Horticulturae, Journal Year: 2025, Volume and Issue: 11(3), P. 337 - 337

Published: March 20, 2025

Accelerated urbanization has intensified nitrogen deposition and fine particulate matter (PM2.5) pollution. While urban landscape plants play a vital role in atmospheric remediation, systematic exploration of their adaptation strategies to these dual stressors remains limited. This study investigated the dynamic responses antioxidant defense systems nitrogen/weight ratios Iris germanica L. Portulaca grandiflora Hook. under four scenarios (N0, N1, N2, N4 with concentrations 0, 15, 30, 60 kg N·hm−2·a−1, respectively) combined constant PM2.5 exposure (50 μg/m3). Through fumigation experiments, we demonstrated that showed higher sensitivity inorganic nitrogen-laden stress than Both species exhibited stronger enzyme (SOD, CAT, POD) activities high-growth season compared low-growth season. Nitrogen allocation analysis revealed maintained stable content across treatments, while progressive loss high exposure. These findings establish Hook.’s superior resilience through two synergistic mechanisms: modulated efficient remobilization. comparative provides actionable insights for selecting pollution-tolerant green infrastructure planning.

Air pollution has become one of the biggest problems throughout world. Smog a severe effect on pulmonary and circulatory systems, which causes significant number deaths globally. Therefore, remediation air pollutants to maintain ecosystem processes functions improve human health is crucial problem confronting mankind today. This review aims discuss effects smog humans. will also focus bioremediation (smog) using bacteria, fungi, phytoremediation, nanotechnology, phylloremediation (using plants microbes). Phyllo-remediation most effective technology for removing naturally. The future perspective presents great need produce an where microbes, plants, nanoparticles synergistically control smog. In addition, further advancements would be needed modify genetic makeup microbes plants.
