Associative interplay of plant growth promoting rhizobacteria (Pseudomonas aeruginosa QS40) with nitrogen fertilizers improves sunflower (Helianthus annuus L.) productivity and fertility of aridisol

Alexandre Buttler, Vincent Eric Jules Jassey, Luca Bragazza

The environmental and economic impacts of chemical fertilizer have encouraged farmers to integrate them with organic materials, an important nutrient management strategy for sustainable agriculture production. In the present study, we conducted field exper ...

Metal accumulation and response of antioxidant enzymes in seedlings and adult sunflower mutants with improved metal removal traits on a metal-contaminated soil

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower mutant lines with an enhanced tolerance and metal accumulation capacity obtained by mutation breeding have been proposed for Zn, Cd and Cu removal from metal-contaminated soils in previous studies. However, soils contaminated with trace elements ...

Increased tolerance of sunflower mutant seedlings to Cd and Zn in hydroponic culture

Jean-Paul Schwitzguebel, Erika Nehnevajova

Cadmium and zinc show similarities in their chemistry, geochemistry and environmental properties. Whereas Cd is a phytotoxic non-essential element, Zn is an essential trace element for plant growth and development. Zinc plays a fundamental role in several ...

Stability of enhanced yield and metal uptake by sunflower mutants for improved phytoremediation

Jean-Paul Schwitzguebel, Erika Nehnevajova

Plant biomass and metal shoot accumulation are key factors for efficient phytoextraction. In a previous study, chemical mutagenesis has been used to improve the phytoextraction potential of sunflowers. The main goal of the present study was to assess the s ...

A Promising Technique to Increase Metal Concentration and Extraction in Sunflowers

Jean-Paul Schwitzguebel, Erika Nehnevajova

Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...

Screening of sunflower cultivars for metal phytoextraction in a contaminated field prior to mutagenesis

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower can be used for the remediation of metal-contaminated soils. Its high biomass production makes this plant species interesting for phytoextraction and using sunflower oil for a technical purpose may improve the economic balance of phytoremediation ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
