The effect of genotype and selenium foliar biofortification in the form of an aqueous solution of sodium selenate on the content of total carotenoids, vitamin C, total polyphenols and selenium content in the tomato fruits was studied.  Field experiment was held in the Botanical garden of the Slovak University of Agriculture in 2016. Seven determinant varieties of tomato in the two variants were observed. The results of experiments show that treatment of plants with the dose of Se concentration (150 g Se.ha-1) at the flowering stage significantly increased the total Se content in the in tomato fruits. Foliar application of selenium had a positive effect on the increase of total polyphenol. The influence of Se biofortification on the content of vitamin C and carotenoids was not detected. Selenium foliar fertilization in dosage 150 g.ha-1 is suitable way of tomato fruits enriching in polyphenols, without negative effect on other antioxidants content.

This paper analyses the effects of soil and foliar fertilization with sodium selenate (VI) on the selenium content in spring wheat grain. The research was carried out at the Departmental Experimental Station of the Institute of Agriculture WULS in Skierniewice in 2018 and 2019. The dose of selenium used was 5.00 g Se·ha−1 in various development stages of spring wheat. The results showed that selenium fertilisation did not affect the size of the grain yield, but both soil and foliar fertilisation significantly increased the content of selenium in wheat grain compared to the control group. The highest Se content was obtained with the method of soil fertilisation combined with the foliar application with a total dose of 10.00 g·ha-1 Se in the stem elongation phase (S + F2), and in the tillering and stem elongation phase (S + F1 + F2), which resulted in the values of 0.615 and 0.719 mg·kg−1 Se in grain, respectively. On this basis, it was concluded that the best time to carry out foliar fertilisation treatment is in the stem elongation phase (BBCH 30–39). The results show that the greatest increase in selenium content in the grain is achieved with soil and foliar fertilisation combined.

Temperature strongly influences the growth of maize, particularly in the early growth stages. The exogenous application of some amino acids has been proven to have a positive effect on plant growth and development under stressful conditions. The objective of the study was to evaluate the response of maize that was grown under an optimal and stress (fluctuating) temperature to L-Arginine (L-Arg) and Glycine (Gly) application. In the study, it was assumed that the exogenously applied amino acids would alleviate the adverse effects of temperature stress on the maize height, as well as on the biomass of shoots and roots. Ten concentrations of each amino acid from 0.006 mM to 9.0 mM were tested under constant temperature conditions 20–22 °C/23–25 °C (night/day) an fluctuating stress of rising and dropping temperatures between 12–15 °C (night) and 30–38 °C (day). The amino acids were applied to the crop at growth stages V3–V4. In plants that were obtained from seeds pre-treated with L-Arg and Gly, the amino acids increased both the length of radicles and the number of lateral roots. A large discrepancy between the effects of the two amino acids was observed after foliar application. Under optimal thermal conditions, L-Arg increased the mass of shoots and roots by 55–59%. Under stress conditions, root mass was increased even by 100% when compared to the control plants. The best results were recorded at concentrations of 6 mM and 3 mM. Plants that were treated with Gly concentrations generally reached the height of untreated plants or less. It was shown that Gly applied at concentrations of 0.2 mM to 3 mM has a negative effect on the fresh mass of the crop.

AbstractThe quality of tomato fruits is influenced by preharvest factors. Trichoderma are considered biostimulants with potential to improve growth and development in plants, as well as the quality of the fruits. The objective of this study was to evaluate the effect of foliar application of Trichoderma on the quality of tomato fruits at different cluster levels on the same plant in two commercial hybrids using three different substrates in a greenhouse. Six foliar applications of a liquid biological preparation of Trichoderma were performed at a dose of 4 mL L−1 every 15 days after transplanting. The results show that the foliar application of Trichoderma increased the ratio of soluble solids to titratable acidity of the fruits at different cluster levels, which was mainly due to the decrease in acidity rather than the increase in soluble solids. The decrease in titratable acidity is in accordance with the increase in the pH of the fruits. Trichoderma have a positive effect on titratable acidity, pH and electrical conductivity of fruits. In the Cid hybrid grown in the tezontle substrate, the application of Trichoderma increased the ratio of total soluble solids to titratable acidity. At the same time, sand increased the percentage of juice in the fruits. Foliar application of Trichoderma increases the quality of tomato fruits, and as such, should be considered as a crop management option.

ABSTRACT The nutritional value of carrot is determined by the content of total sugars and monosaccharides, carotenoids and vitamins, including vitamin C, in its roots. In 2009-2011, field experiments were carried out concerning the effect of biostimulating preparations applied during the carrot vegetation period on selected nutrients of its roots (total sugars, monosaccharides, carotenoids and vitamin C). Two biostimulants were foliarly applied in doses of 2 or 3 L ha-1 on various dates. Kelpak SL and Asahi SL: one, two or three applications; where, second and third applied at 2-week interval, additionally Kelpak SL: one application at 4-leaf phase, followed by additional application after 4 weeks. The field study was conducted in a randomized block design with four replications. The treatments of plant protection from diseases and pests complied with carrot requirements. The subject of the research was carrot of the Karotan cultivar. The content of selected components in carrot roots was determined directly after harvest and after six months of storage in the storage chamber with controlled temperature and relative air humidity. The foliar application of Kelpak SL in a single dose (2 L ha-1) at 4-leaf development phase resulted in the significant increase of total sugars, reducing sugars, total carotenoids and vitamin C. A six-month storage period resulted in a decrease of total sugars by 5% and ascorbic acid by 16.8% compared to nutritional values measured right after harvest.

The Given

The favourable active ingredient composition of numerous vegetables is published frequently; however its value is often influenced by the variety and the given production year. In the current experiment the main aim was to determinate the bioactive materials (total polyphenol, flavonoid, vitamin C, sulphate-S, protein, nitrate-ion) of blanched (white) asparagus for three widely known varieties (‘Cumulus’, ‘Vitalin’, ‘Grolim’), grown on mouldy brown sandy soil, in 3 consecutive years (2012- 2014). A significant difference has been found among the varieties in the average of the observed data. ‘Vitalin’ was prominent with its high total polyphenol (35.16 mg/100 g), vitamin C (59.34 mg/100 g) and flavonoid (0.52 mg/100 g) content. High sulphate-S content - which is characteristic for asparagus - has been measured in the case of ‘Cumulus’ (287.77 mg/100 g), together with the highest protein content (2.23%). The vitamin C content of the spears is significantly influenced by the production year, therefore higher temperature fluctuations had a negative effect on it, which resulted in its value reducing to one-tenth of the best years in some cases (89.06 mg/100 g). Additionally, it has been found that white asparagus develops under etiolated circumstances, it is not inclined to nitrate accumulation, which is well represented by the values under 20 mg/kg. Selecting the proper cultivar is important for raw asparagus extract production, which can be produced only of raw materials rich in bioactive materials (including high sulphur content). In this regard ‘Vitalin’ and ‘Cumulus’ seemed to be the most advantageous choices.

Selenium (Se) is a micronutrient that is insufficiently present in the human diet. Increasing its content in food through appropriately matched agricultural practices may contribute to reducing Se deficit in humans. The study covered the effect of grain, soil, as well as grain and soil fertilization with selenium combined with foliar application at different stages of spring wheat (Triticum aestivum L.) development. The fertilization involved the application of sodium selenate. Fertilization with selenium had no significant effect on the grain yield. Grain application, soil application, and grain and soil application combined with foliar application at particular development stages of the plant significantly contributed to an increase in selenium content in grain. The study showed that the accumulation of selenium in spring wheat depends on the type of fertilization and term of its application. The best method of introducing selenium into the plant is grain and soil fertilization combined with foliar application at the stage of tillering and stem elongation (G + S+F1-2) for which the highest selenium content was obtained (0.696 mg·kg−1 Se). The applied biofortification methods contributed to the increase in selenium in the grain of spring wheat.

AbstractIn field experiments, tartary buckwheat and hybrid buckwheat were foliarly sprayed with an aqueous solution of sodium selenate (20 mg Se L-1). In treated plants, the selenium content was significantly higher than in controls, irrespective of the plant part and taxon of buckwheat. The highest average Se concentrations in hybrid and tartary buckwheat were found in seeds. The main Se species found in seeds was Semethionine. Selenium-sprayed plants had higher photochemical efficiency of photosystem II in both taxa and higher electron transport system activity in hybrid buckwheat, suggesting a positive effect of Se on physiological characteristics. Because of the concentration of Se in both buckwheat taxa and selenomethionine as the dominant species of Se, Se-enriched buckwheat is a potential source of dietary Se for animals and humans.

A two-year field study was conducted to determine the effect of different Se fertiliser application methods and application rates on the selenium content in maize plants. Selenium as sodium selenate was added into soil (10 g and 20 g Se ha-1) or sprayed on maize plants (20 g Se ha-1). Maize plants from control treatment contained 0.018 and 0.020 mg Se kg DM-1 in the first and the second year of the study. Foliar application exhibited superior effect by increasing selenium content in the plants up to 0.343 mg kg DM-1 in the first year, and 0.249 mg kg DM-1 in the second. Soil selenium application was less effective; selenium content in maize plants varied from 0.018 to 0.019 mg kg DM-1 in the first and from 0.018 to 0.145 mg kg DM-1 in the second year, respectively. Strong linear correlation (r=0.71) was found between selenium content in the plants and in grains. Selenium recovery rates were significantly higher in case of foliar treatment compared to soil application.
