Summary: This study investigates the role of citric acid and chromium-resistant bacteria in remediating hexavalent chromium (Cr+6) from polluted soil using castor bean. Results showed that high concentrations of chromium negatively affected plant growth, while the application of citric acid improved plant growth. Staphylococcus aureus was found to be more effective in tolerating chromium toxicity compared to Bacillus subtilis. Castor bean demonstrated excellent potential in tolerating high chromium concentrations and can be effectively used in phytoremediation of metal-contaminated soil. The combined use of citric acid and metal-resistant bacteria can significantly enhance the phytoremediation potential of castor bean and other hyper-accumulator plants.

Summary: This study investigated the effectiveness of using a plant growth regulator, 5-aminolevolinic acid (ALA), to enhance the remediation of chromium (Cr)-contaminated soils by sunflower plants. The results showed that ALA promoted plant growth and ameliorated cellular injury from Cr stress by modulating antioxidant enzymes and eliminating reactive oxygen species.

Summary: Pollution of the environment due to toxic metals such as arsenic (As) is a global issue affecting millions of people. Phytoremediation, specifically using Helianthus annuus plants, is an effective strategy for removing As from polluted soil. Pot experiments were conducted to evaluate morphological and biochemical changes, as well as enzyme activity analysis. Results showed that the root had the highest As concentration, while the shoot had the lowest. Optimum proline and polyphenol concentrations were observed with increasing As concentrations. Higher antioxidant enzymatic activity was observed at 60 days. FESEM-EDX and optical microscopy analyses confirmed the transport of arsenic in root and shoot tissues. These findings support the use of H. annuus for As removal and sustainable agriculture farming.

Summary: This research focused on using ornamental plants Helianthus annuus and Tagetes erecta for the phytoremediation of zinc-contaminated soil. The findings showed that Helianthus annuus had a better ability to mitigate zinc compared to Tagetes erecta. It is suggested that Helianthus annuus can be used as an effective accumulator of zinc in soil cleanup.

Summary: This study demonstrated the feasibility of the Gynostemma pentaphyllum/Helianthus annuus intercropping system in arsenic contaminated farmland and proposed the use of stabilizing materials to regulate plant arsenic absorption. The application of stabilizing materials significantly reduced arsenic concentration in Gynostemma pentaphyllum leaves and increased arsenic bioaccumulation in Helianthus annuus plants in the intercropping system.

Summary: This study investigated the effects of nickel application on physiological and biochemical attributes of sunflower cultivars grown in sand culture. Results showed that increasing nickel concentration significantly decreased vegetative parameters and photosynthetic attributes, while low levels of nickel improved growth attributes to some extent. The study also found that high nickel concentration had negative effects on leaf water potential, osmotic potentials, and relative water contents, but increased leaf turgor potential and membrane permeability. Hysun-33 exhibited higher tolerance to nickel stress compared to SF-187.

Summary: The study found that the accumulation of Cr(VI) was two to three times higher in roots than in shoots, indicating that the root is the major site of Cr(VI) accumulation. Under Cr(VI) toxicity, photosynthetic pigments, leaf gaseous exchange parameters, and F-v/F-m efficiency worsened. Cr(VI) accumulation intensified lipid peroxidation by triggering the production of MDA and H2O2, but the plant responded effectively by enhancing the coordinated action of enzymatic and non-enzymatic antioxidants.

Summary: The study focused on the effect of varying sowing dates on sunflower genotypes' seed dormancy levels, finding that late sowings can increase germination rates and accelerate dormancy release. The sensitivity of embryos to ABA inhibition may play a role in alleviating dormancy in sunflower seeds.

Summary: Seven undescribed compounds, along with eighteen known compounds, were isolated from the water extract of Helianthus annuus L. flowers. The structures of these compounds were determined through spectroscopic analysis. Compound 6 exhibited significant inhibitory activity on the release of NO in MH-S cells, while compound 18 showed moderate inhibitory activity.

Summary: The concerns on weed control through herbicides are increasing due to their negative impacts on environment and human health. Therefore, alternative weed management methods are inevitable for sustainable crop production and lowering the negative consequences of herbicides. This study evaluated the role of different mulching treatments on suppressing weed flora in maize and sunflower crops. The results showed that plastic mulch and paper mulch had the highest suppression of weed flora compared to other treatments and significantly improved the productivity of both crops.

Summary: The study found that chelators EDDS/CA significantly increased Cd accumulation but inhibited plant growth of sunflower, while ALA promoted both Cd absorption and biomass accumulation, especially when applied in combination with EDDS. ALA protects sunflower plants from Cd-induced cellular injury by immobilizing Cd ions, modulating activities of antioxidative enzymes, and capturing reactive oxygen species.
