“…The effectiveness of organic amendments in enhancing crop production is significantly augmented by the combined application with microelements (non-essential elements for plants with high potential for promoting plant growth and development at very low concentrations). Examples of these elements include boron (B), selenium (Se), cobalt (Co), titanium (Ti), silicon (Si), aluminum (Al), and vanadium (V), which play relevant roles in mastering plant growth and resistance to abiotic stresses [ [44] , [45] , [46] ]. These elements reduce the harmful effects of salinity by inducing antioxidant systems, carbohydrate content, chlorophyll content, plant biomass, and crop yield.…”

“…However, Sb increased the activity of antioxidant enzymes, which confirmed that Sb induces oxidative stress. The biostimulants of various chemical and biological compositions (including organic and inorganic compounds) were tested to elucidate their potential to alleviate the impact of heavy metal stress on plants [ 30 , 34 ]. The tested organic biostimulants are different types of phytohormones such as auxins, cytokinins, abscisic acid, and gibberellins [ 30 ], while Si, Se, Co, and Al are commonly investigated inorganic stimulants [ 34 ].…”

It is very important to mention that the positive effects of all biostimulants depend on the concentration used.…”

The presence of antimony (Sb) in high concentrations in the environment is recognized as an emerging problem worldwide. The toxicity of Sb in plant tissues is known; however, new methods of plant tolerance improvement must be addressed. Here, poplar callus (Populus alba L. var. pyramidallis) exposed to Sb(III) in 0.2 mM concentration and/or to silicon (Si) in 5 mM concentration was cultivated in vitro to determine the impact of Sb/Si interaction in the tissue. The Sb and Si uptake, growth, the activity of superoxide dismutase (SOD), catalase (CAT), guaiacol-peroxidase (G-POX), nutrient concentrations, and the concentrations of photosynthetic pigments were investigated. To elucidate the action of Si during the Sb-induced stress, the impact of short and long cultivations was determined. Silicon decreased the accumulation of Sb in the calli, regardless of the length of the cultivation (by approx. 34%). Antimony lowered the callus biomass (by approx. 37%) and decreased the concentrations of photosynthetic pigments (up to 78.5%) and nutrients in the tissue (up to 21.7%). Silicon supported the plant tolerance to Sb via the modification of antioxidant enzyme activity, which resulted in higher biomass production (increased by approx. 35%) and a higher uptake of nutrients from the media (increased by approx. 10%). Silicon aided the development of Sb-tolerance over the longer cultivation period. These results are key in understanding the action of Si-developed tolerance against metalloids.

“…The application of selenium at beneficial doses under various forms (selenium salts, zerovalent nanoselenium, organic selenium) on plants, as soil or foliar treatments, determines effects similar to those defining plant biostimulants, the enhancement of mineral nutrients uptake [ 15 , 23 ], the utilization increased resistance to stress [ 24 , 25 , 26 ], and improved quality traits [ 27 , 28 , 29 ]. Selenium was mentioned in the category of inorganic plant biostimulants [ 7 , 30 , 31 , 32 ] and was widely recognized as a plant protection product against abiotic stress [ 24 , 33 ]. In the area with selenium deficit, selenium application combines biofortification, i.e., selenium supplementation of the food chains with the plant protection against abiotic stress—“protective biofortification” [ 34 , 35 ].…”

The main aim of this study is to find relevant analytic fingerprints for plants’ structural characterization using spectroscopic techniques and thermogravimetric analyses (TGAs) as alternative methods, particularized on cabbage treated with selenium–baker’s yeast vinasse formulation (Se-VF) included in a foliar fertilizer formula. The hypothesis investigated is that Se-VF will induce significant structural changes compared with the control, analytically confirming the biofortification of selenium-enriched cabbage as a nutritive vegetable, and particularly the plant biostimulant effects of the applied Se-VF formulation on cabbage grown in the field. The TGA evidenced a structural transformation of the molecular building blocks in the treated cabbage leaves. The ash residues increased after treatment, suggesting increased mineral accumulation in leaves. X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) evidenced a pectin–Iα-cellulose structure of cabbage that correlated with each other in terms of leaf crystallinity. FTIR analysis suggested the accumulation of unesterified pectin and possibly (seleno) glucosinolates and an increased network of hydrogen bonds. The treatment with Se-VF formulation induced a significant increase in the soluble fibers of the inner leaves, accompanied by a decrease in the insoluble fibers. The ratio of soluble/insoluble fibers correlated with the crystallinity determined by XRD and with the FTIR data. The employed analytic techniques can find practical applications as fast methods in studies of the effects of new agrotechnical practices, while in our particular case study, they revealed effects specific to plant biostimulants of the Se-VF formulation treatment: enhanced mineral utilization and improved quality traits.
