This study examined the chemical response of Ligustrum lucidum Ait. and Ligustrum lucidum Ait. f. tricolor (Rehd.) Rehd. when exposed to different sources of atmospheric pollutants. Dry weight/fresh weight ratio, specific leaf area (SLA), sulfur content, chlorophyll concentration, carotenoids, soluble proteins, malondialdehyde (MDA) and hydroperoxy conjugated dienes (HPCD) were determined for leaf samples taken from different sites in the city of Córdoba, Argentina. These sites were categorized in terms of their traffic levels and industrial levels. Both L. lucidum as well as L. lucidum f. tricolor accumulated sulfur in their leaves in sites with high traffic levels, the former being the most sensitive to this type of pollution. Ligustrum lucidum exhibited significantly low concentrations of soluble proteins, in sites with high industrial pollution levels. Ligustrum lucidum f. tricolor did not exhibit a significant response to industrial pollution.

这项研究检查了女贞的化学响应。和女贞。f.三色 (Rehd。) 当暴露于不同的大气污染物来源时。测定了从阿根廷科尔多瓦市不同地点采集的叶片样品的干重/鲜重比,比叶面积 (SLA),硫含量,叶绿素浓度,类胡萝卜素,可溶性蛋白质,丙二醛 (MDA) 和氢过氧共轭二烯 (HPCD)。这些站点根据其流量水平和工业水平进行了分类。L. lucidum和L. lucidum f. tricolor都在流量高的地方的叶子中积累了硫,前者对这种类型的污染最敏感。在工业污染水平高的地方,女贞表现出明显低浓度的可溶性蛋白质。女贞三色对工业污染没有明显的反应。
