In this study, the potential of , a freshwater fern species, on phenanthrene phytoremediation and biodegradation was investigated. Furthermore, the effect of phenanthrene on growth performance, photosynthetic activity and biosynthesis, and accumulation of secondary metabolites of were evaluated. Plants were grown in a nitrogen-free Hoagland and exposed to different phenanthrene concentrations (0, 1, 5, and 10 mg/L). Exposure to 10 mg/L phenanthrene caused a significant reduction (42%) in growth compared to control on day 14. The photosynthetic pigment content of treated with 1 and 5 mg/L was almost the same as the control, while 10 mg/L phenanthrene was significantly reduced. In comparison to unplanted controls, the biodegradation percentages obtained from the planted growth medium were found to be 88, 69, and 60%, respectively, for the application of 1, 5, and 10 mg/L phenanthrene. Data on plant growth, photosynthetic pigments, secondary metabolite contents, and biodegradation percentages indicated the tolerance level and the effective phytoremediation potential of for phenanthrene was <10 mg/L. The results indicated that is highly effective in phytoremediation of low concentrations of phenanthrene pollution in a short time.
在本研究中，对一种淡水蕨类植物在菲的植物修复和生物降解方面的潜力进行了研究。此外，还评估了菲对该植物生长性能、光合活性、生物合成以及次生代谢产物积累的影响。将植物种植在无氮的霍格兰培养液中，并暴露于不同浓度的菲（0、1、5和10毫克/升）下。在第14天，与对照相比，暴露于10毫克/升菲导致该植物生长显著降低（42%）。用1和5毫克/升菲处理的该植物光合色素含量与对照几乎相同，而10毫克/升菲使其显著降低。与未种植的对照相比，在种植的生长培养基中，对于1、5和10毫克/升菲的应用，获得的生物降解百分比分别为88%、69%和60%。关于植物生长、光合色素、次生代谢产物含量和生物降解百分比的数据表明，该植物对菲的耐受水平和有效的植物修复潜力为<10毫克/升。结果表明，该植物在短时间内对低浓度菲污染的植物修复非常有效。
