摘要

本研究旨在分析采石场污染对药用野生荆芥(Rubus plicatus Weihe & Nees)形态解剖学、生物化学和生理学的影响。样本采集自两个自然保护区:样本采集自两个自然保护区:铁门自然公园和九峡谷国家公园(均位于罗马尼亚西南部),以及这两个公园中两个未受污染的区域作为背景地点。我们对收集到的该类群的叶片进行了以下分析:形态学、微形态学、解剖学、同化色素、重金属(铅、镍、铬、铁)、干重、生物活性化合物(总酚和类黄酮)以及抗氧化能力。结果表明,与无污染源地区相比,污染地区的茜草叶片气孔更多,同化色素含量更高,重金属(尤其是铅)含量更高,干重更轻,酚类更少,类黄酮含量更高。气孔数量和同化色素含量的增加揭示了该物种在污染条件下生存的机制。

Rubus plicatus Weihe & Nees: resilience to pollution caused by stone quarries
This study aimed to analyze the effect of pollution caused by stone quarries on the morpho-anatomy, biochemistry, and physiology of a medicinal wild bramble Rubus plicatus Weihe & Nees. Samples were collected from two natural protected areas: Iron Gates Natural Park and Jiu Gorge National Park, both located in the southwestern part of Romania, and two unpolluted areas from these parks as background sites. We carried out the following analyses on the collected leaves of this taxon: morphology, micromorphology, anatomy, assimilating pigments, heavy metals (Pb, Ni, Cr, Fe), dry mass, bioactive compounds (total phenols and flavonoids), and antioxidant capacity. The results showed more stomata, higher amounts of assimilating pigments, higher amounts of heavy metals (especially lead), less dry mass, less phenols, and more flavonoids in Rubus plicatus leaves from polluted areas compared to areas without sources of pollution. The increased number of stomata and the amounts of assimilator pigments revealed the mechanisms developed by this species in order to survive in polluted conditions.
