In this study, we investigated the effects of Zn concentrations (40, 80, 160, 240, 320, 400 mg L\u22121) on plant growth, root morphology, chlorophyll fluorescence, and Zn accumulation in Potentilla chinensis grown in soil for 21 days. The results showed that total root length, root surface area, root volume, qP, qL, ETR, and SPAD values responded at \u2264240 mg L\u22121, whereas plant height was affected at 400 mg L\u22121, indicating that SPAD, some fluorescence, and root traits responded before major biomass effects became statistically significant. At 400 mg L\u22121, shoot and root Zn concentrations reached 1353.75 and 187.16 mg kg\u22121 DW, respectively, and the translocation factor was 7.24. Fm, Fv, Fv\/Fm, and \u03a6PSII remained stable, whereas F0 decreased and NPQ increased, indicating that PSII function was largely maintained, with partial reaction center damage offset by enhanced protective thermal dissipation. Shoot Zn concentrations exceeded root Zn concentrations across all treatments, indicating efficient root-to-shoot Zn translocation. These findings show that P. chinensis exhibits Zn accumulation and efficient root-to-shoot translocation under the tested conditions and warrants further investigation as a candidate species for Zn phytoextraction.<\/jats:p>","DOI":"10.3390\/life16091562","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T09:59:03Z","timestamp":1789639143000},"page":"1562","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Zinc Toxicity on Chlorophyll Fluorescence and Translocation Factor of Potentilla chinensis"],"prefix":"10.3390","volume":"16","author":[{"given":"Yue","family":"Wang","sequence":"first","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"given":"Yu","family":"Qiao","sequence":"additional","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Sen","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5693-3924","authenticated-orcid":false,"given":"Weizhou","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Yaojun","family":"Bo","sequence":"additional","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Xia","family":"Han","sequence":"additional","affiliation":[{"name":"College of Advanced Agricultural Sciences, Shaanxi Engineering Research Center of Forage Plants of the Loess Plateau, Yulin University, Yulin 719000, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"677","DOI":"10.1111\/j.1469-8137.2007.01996.x","article-title":"Zinc in plants","volume":"173","author":"Broadley","year":"2007","journal-title":"New Phytol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1134\/S1021443711010079","article-title":"Induction of oxidative stress and antioxidant responses in Vigna mungo by zinc stress","volume":"58","author":"Gupta","year":"2011","journal-title":"Russ.
