The current study aims to reduce the access of toxic elements to the oil extracted from basil plants growing in polluted soils by biochar and NPS of silicon (Si) and boron (B). Sweet basil plants were grown in contaminated soil that contained cadmium (Cd) and lead (Pb) at concentrations of 58 and 800 mg kg⁻¹, respectively. The experiment included two doses of biochar (0 and 1%, w/w) and four foliar combinations of Si and B nanoparticles at the dose of 100 mg L⁻¹ of Si and/or B. Cd and Pb availability were reduced by 44 and 48%, respectively, compared to the control. The soil pH raised significantly (<i>p</i> &lt; 0.05) as a result of biochar addition. Furthermore, biochar addition at the dose of 1%, (w/w) caused a 14% increase in the soil organic matter. The highest growth parameters of basil plants were obtained from the biochar treatment with Si + B NPs foliar application. The treatment that was amended with biochar and sprayed with Si + B showed the greatest significant values of nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) content in basil plants. The chlorophyll content of basil leaves rose along with the synthesis of proline and soluble carbohydrates after the addition of biochar to the polluted soil and Si + B spraying. Biochar minimized Cd in the leaf and oil by 48 and 49%, respectively, compared to the control, while Pb concentrations were reduced by 29 and 49%, respectively. The oil extracted from the basil plants grown in the soil amended with biochar contained 50–52 and 23–26 μg kg⁻¹ of Cd and Pb, respectively. Adding biochar to the contaminated soil increases the oil yield of sweet basil and reduces its content of toxic elements, while spraying the basil plant with silicon and boron nanoparticles increases the plant’s resistance to metal toxicity.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":"46 7","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chlorophyll (Chl) content, osmotic adjustment substances content, and antioxidant enzyme activities were measured at 7, 14, 21, and 28 days. The results revealed that the tolerance of the three bryophyte species to Pb or N stress was in the order of <i>P. acutum</i> &gt; <i>B. argenteum</i> &gt; <i>S. caninervis</i>, which was closely related to the conditions of their respective natural habitats. <i>S. caninervis</i> and <i>B. argenteum</i> were stress tolerant for 7 days and <i>P. acutum</i> for 14 days. The bryophytes were tolerant to Pb or N stress after the contents of osmoregulatory substances and antioxidant enzyme activities increased; however, as toxicity accumulated over time, all three species suffered irreversible damage, as indicated by an abrupt decrease in the Chl content and osmoregulatory substances, as well as a sudden drop in antioxidant enzyme activities. Under the combined effects of Pb-N stress, the Chl content, osmoregulatory substance contents, and antioxidant enzyme activities were significantly higher in the N-loving <i>P. acutum</i> (N produced significant benefits) than in <i>P. acutum</i> exposed to Pb stress alone. This phenomenon is likely because Pb and N have antagonistic effects on the growth of <i>P. acutum</i>; thus, their recombination generates a counter-balancing effect. In the N-sensitive species, <i>S. caninervis</i> and <i>B. argenteum</i> (N caused obvious toxicity), the indicators were slightly better than under N tress alone (indicated by the reduction of membrane lipid peroxidation and increased osmoregulatory substance contents and enzyme activities), suggesting that there is a certain antagonistic effect exerted by the simultaneous addition of Pb and N.

The metal-chelating properties of CS can regulate the release of Zn²⁺ ions from the NPs, reducing their availability to plants and mitigating potential toxicity. In the present work, the effect of ZnO NPs and CS/ZnO NCPs at two different concentrations, i.e., 100 and 200 ppm, has been tested on <i>Sorghum bicolor</i> plants. The ZnO NPs and CS/ZnO NCPs were chemically synthesized and characterized with various microscopic and spectroscopic techniques. Plants grown in ZnO NPs-treated soil for 30 days exhibited reduced growth, decreased chlorophyll, starch, and cellulose levels as well as nutrient (K, Mg and P) uptake. In addition, these nanoparticles increased malondialdehyde (MDA) content and the activities of antioxidant enzymes in the shoots, indicating their phytotoxicity to <i>S. bicolor</i> plants. Conversely, CS/ZnO NCPs application stimulated plant growth, nutrient uptake, chlorophyll and starch contents, while reducing MDA content and superoxide dismutase activity. The CS/ZnO NCPs-treated plants also accumulated 2.5–3.5 times less Zn²⁺ than ZnO NP-treated plants.

In the transcriptomic profiling, the purple phenotype had 754 up-regulated and 980 down-regulated genes compared with the green <i>F. cirrhosa</i>, in which a total of 37 significant differential expression genes (DEGs) regulated the anthocyanin biosynthesis by coding 6 vital enzymes (C4H, F3′H, ANS, DFR, DFT, and BA1).

Therefore, the study was carried out to investigate the variations in morpho-biochemical characteristics of different spinach accessions based on bolting time. This study aims to find out whether or not bolting time causes morpho-biochemical changes in different spinach accessions.

This spring field experiment was set up in a complete randomized block of 3 replicates and 18 observations. The results revealed significant differences between the early- and late-bolting spinach accessions (comparisons between groups) in their leaf number, plant height, yield, fresh and dry shoot weight, day to bolting, flavonoid, phenol, vitamin C, carbohydrate, nitrate, calcium (Ca), and iron (Fe) content.
