Abstract
The use of essential beneficial elements such as iodine and selenium in biofortification, the application of trace metal nanoparticles (NPs) as fertilizers and biostimulants, the use of grafted plants and the use of beneficial microorganisms constitute a group of techniques to increase the productivity, nutraceutical quality and stress tolerance of greenhouse crops.
The application of the techniques mentioned above can be facilitated by combining it with the use of chitosan-polyacrylic acid (CS-PAA) complexes, CS hydrogels, and of CS-polyvinyl alcohol hydrogels (CS-PVA). The above compounds, due to their CS content, exhibit biostimulant activity and through chelation, absorption or adsorption allow the slow release of trace metal, NPs, and selenium and iodine ions, as well as increasing the effectiveness of beneficial microorganisms immobilized in biopolymers.
This paper includes the results obtained in different studies carried out by our group in the area of application of the CS complexes in combination with the three techniques mentioned above.
The results obtained in recent years are presented, discussing them in the context of the results of other working groups.
The studies conclude that the CS-PAA complexes, CS, and CS-PVA hydrogels 1) allow a greater effectiveness in the biofortification with Se and I in plants in soilless system under greenhouse; 2) increase the impact on the growth, yield, and nutraceutical quality of the Cu NPs, applied in peat moss and perlite in quantities as low as 0.006 mg L‑1; 3) favor the growth and activity of antioxidant enzymes in grafted plants and, finally, 4) improve the response of plants to the application of Trichoderma sp.
The manuscript concludes by indicating the areas of opportunity to carry out research and innovation aimed at greenhouse crops using CS-PAA complexes, CS, and CS-PVA hydrogels.
