Dwarf bamboo Sasa argenteostriata (Regel) E.G. Camus has previously been considered as potential plant for metal phytoremediation. However, the dynamic responses and correlations among physiological resistances to high-concentration Pb exposure have not been described to date. This study conducted four Pb treatments (0, 1500, 3000, and 4500 mg kg^–1) to examine the physiological resistance responses at days 7, 14, and 21. The findings showed that S. argenteostriata can regulate both the enzymatic system and the nonenzymatic system to synergistically overcome Pb damage. In addition, a significant positive correlation was found between enzymes and nonenzymatic substances, which were particularly apparent with regard to the superoxide dismutase (SOD) activities with phytochelatins (PCs) levels, peroxidase (POD), and glutathione reductase (GR) activities with glutathione (GSH) levels, as well as catalase (CAT) and ascorbate peroxidase (APX) activities with soluble protein (SP) levels. Furthermore, Pb concentration was the main factor that induced the physiological responses of S. argenteostriata to Pb stress. The antioxidant enzyme system and the AsA–GSH cycle were dominant resistance mechanisms under 1500 mg kg^–1 Pb. AsA–GSH cycle and plant cell chelation were dominant resistance mechanisms under 3000 mg kg^–1 Pb. Antioxidant enzymes and plant cell chelation were dominant resistance mechanisms under 4500 mg kg^–1 Pb. This study provides comprehensive evidence regarding how both enzymatic and nonenzymatic systems of S. argenteostriata cooperate to alleviate the high-concentration soil Pb stress. The results highlight the environmental remediation potential of this species for Pb-contaminated media.

矮竹Sasa argenteostriata（Regel）EG Camus以前被认为是金属植物修复的潜在植物。但是，迄今为止尚未描述对高浓度Pb暴露的生理抗性的动态响应和相关性。这项研究进行了4种Pb处理（0、1500、3000和4500 mg kg ^-1），以检查在第7、14和21天的生理抗性反应。研究结果表明，S。argenteostriata可以调节酶系统和非酶系统以协同克服Pb的损害。另外，在酶和非酶物质之间发现了显着的正相关，这在具有植物螯合素（PCs）水平的超氧化物歧化酶（SOD）活性，具有谷胱甘肽的过氧化物酶（POD）和谷胱甘肽还原酶（GR）活性方面尤为明显。 （GSH）水平，以及过氧化氢酶（CAT）和抗坏血酸过氧化物酶（APX）的活性与可溶性蛋白（SP）的水平。此外，铅的浓度是诱导银纹葡萄球菌对铅胁迫的生理反应的主要因素。在1500 mg kg ^–1下，抗氧化酶系统和AsA–GSH循环是主要的抗性机制。铅 在3000 mg kg ^–1 Pb下，AsA–GSH循环和植物细胞螯合是主要的抗性机制。在4500 mg kg ^–1 Pb下，抗氧化酶和植物细胞螯合是主要的抗性机制。这项研究提供了关于阿根廷银链霉菌的酶促和非酶促体系如何协同缓解高浓度土壤铅胁迫的综合证据。结果强调了该物种对受Pb污染的介质的环境修复潜力。
