Abstract

Heavy metal contamination is an increasingly pressing global ecological concern adversely affecting plant growth. Phytoremediation is an eco-friendly and low-cost approach to help solve this problem by using plants to remove metals. This study aimed to evaluate the phytoremediation potential of four Plantago species, exposing them to different concentrations (0, 150, 300, 600 and 900 ppm) of zinc, copper, and iron during germination and early seedling growth. These are generally the phases of the plant life cycle most sensitive to stress. The germination percentage (GP), mean germination time (MGT), radicle, hypocotyl and cotyledons length, biomass, water content and tolerance index (TI) were recorded under controlled conditions. The results indicated that metal-induced stress significantly reduced GP, increased MGT, and inhibited seedling growth with increased metal concentration. The relative toxicity of the tested metals could be ranked as Fe > Cu > Zn. Regarding the Plantago species, P. tunetana and P. lanceolata could be considered highly tolerant, P. albicans moderately tolerant, and P. afra low-tolerant to metal toxicity during germination. Therefore, P. tunetana and P. lanceolata present an excellent potential for phytoremediation of metal-contaminated zones.
四种车前草的发芽和幼苗生长对锌、铜和铁的反应
重金属污染是一个日益紧迫的全球生态问题,对植物生长造成不利影响。植物修复是一种生态友好且成本低廉的方法,通过利用植物去除金属来帮助解决这一问题。本研究旨在评估四种车前草的植物修复潜力,在它们发芽和幼苗生长期间,将它们暴露在不同浓度(0、150、300、600 和 900 ppm)的锌、铜和铁中。这些阶段通常是植物生命周期中对胁迫最敏感的阶段。在对照条件下记录了发芽率(GP)、平均发芽时间(MGT)、胚根、下胚轴和子叶长度、生物量、含水量和耐受指数(TI)。结果表明,随着金属浓度的增加,金属诱导胁迫会显著降低 GP 值,增加 MGT 值,并抑制幼苗的生长。受测金属的相对毒性依次为铁 > 铜 > 锌。在车前草物种中,P. tunetana 和 P. lanceolata 对萌芽期金属毒性的耐受性较高,P. albicans 的耐受性一般,P. afra 的耐受性较低。因此,P. tunetana 和 P. lanceolata 具有对金属污染区进行植物修复的巨大潜力。
