“…Both the application of Se via the root-zone (in nutrient medium) and in foliar spraying significantly increased concentration of Se in lettuce leaves and roots [28]. Similarly as in the described study it was found that an Se addition (in concentration of 0.5 and 1.0 mg Se dm -3 to the nutrient solution) resulted in an increase in the Se concentration in leaves, which had a positive impact on plant yielding [36]. Increasing Se nutrition has an effect on the concentration of that element in plants [26,37,38].…”

Mn, as Fe, Zn, Cu and Ni is a heavy metal and also a necessary element all the living organisms. Excessive Mn nutrition causes a strong oxidative stress. The aim of the studies was to determination the effect of Se treatment (as sodium selenite Na2O4Se3) to alleviate the Mn stress of plants. Because of its sensitivity to oxidative stress induced by excessive concentrations of Mn a model plant was lettuce (Lactuca sativa L. 'Sunny'). ). In all the combination were also tested different foliar sprays (distilled water and a 0.005% Se solution). Plants grown under conditions described above take up and transported Se from nutrient solutions into their leaves with a significant reduction of Mn concentration and changes in the plant nutrient status. With the increase in the concentrations of Se clearly narrowed quantitative relations in the leaves between this element and micro-metallic. Increasing Se levels in nutrient solution has a positive influence on the growth of plants, but Se foliar treatment generally decreases plant yield. The study shown that Se application may lead to alleviation of Mn stress of plants, with simultaneous reduce in Mn concentration in leaves -which may be of practical importance also in the cultivation of more economically important species.

“…On the other hand, considering alfalfa, chicory and cucumber, the Se concentration levels were comparable. 13,16,20,21,50 However, the larger the Se uptake the greater may be its influence in other nutrient absorption and it may upset the nutritional balance of the plant. Thus, for a better understanding of this influence, the results obtained for the nutrient concentrations were also evaluated by principal components analysis.…”

The effect of selenate and selenite enrichment on mineral composition of a red type of lettuce cv. "Veneza roxa" was evaluated using inductively coupled plasma-optical emission spectroscopy (ICP OES), molecular modeling and principal component analysis (PCA). Both Se species did not show toxicity, while selenate promoted the greatest Se accumulation by the plant. There was an increase of 886 µg of Se per 100 g of fresh sample at different concentrations of selenate, but for selenite the maximum variation was only of 114 µg per 100 g. Selenate promoted the absorption of Mo and S and the reduction of K, Mn and P, meanwhile selenite increased Mn and decreased Mo accumulation. Copper and Fe absorption was negatively affected, Ca and Mg showed a slight increase, and Na and Zn were not affected by Se species. Despite the changes in the nutritional balance, Se-enriched lettuce can still be considered a potential dietary source of this essential element.

“…1). Selenium maintained cherry tomatoes, lettuce and chicory quality by suppressing respiration rate and ethylene production at harvest time and during storage (Malorgio et al, 2009;Pezzarossa et al, 2014;Zhu et al, 2017). The lowest respiration rate and ethylene production are desirable to maintain quality and increase shelf life of cherry tomatoes.…”

Tomatoes have high nutritional and economical value and its deterioration start after harvest. They need proper treatments to increase and maintain quality as well as shelf life. The objective of this study was to determine the effect of iron, iodine and selenium on quality, shelf life and microbial activity of cherry tomatoes. Iron (1 mg/L), iodine (1 mg/L) and selenium (1 mg/L) were supplied with nutrient solution for five weeks prior to harvest. Then, cherry tomatoes were stored at 5 °C to assess quality, shelf life and microbial activity. The highest Ca content (p < 0.05) revealed in selenium-treated cherry tomatoes. Lower respiration and ethylene production were showed in selenium-treated cherry tomatoes both harvest time and after storage compared with iron and iodine treatments. At harvest time and after storage, the respiration were 1.29 (p < 0.05) and 0.62 mL/kg/hr (p < 0.01), respectively in selenium-treated cherry tomatoes. Moreover at harvest time and after storage in selenium-treated cherry tomatoes, the ethylene production was 2.11 and 0.87 μL/kg/hr (p < 0.01), respectively. The lowest fresh weight loss, the longest shelf life (p < 0.01), the least fungal incidence rate and microbial activities were found in selenium-treated cherry tomatoes. The longest shelf life of selenium-treated cherry tomatoes was 22 days. Selenium-treated cherry tomatoes' firmness increased (16.82N) at harvest time (p < 0.05) and it was significantly retained (12.70N) after storage (p < 0.01). Color development and lycopene content were more suppressed by selenium treatment after storage than iron and iodine treatments. Titratable acidity, vitamin C and soluble solids increased in selenium-treated cherry tomatoes after storage. Based on results, selenium-treated cherry tomatoes have significant potential to increase and maintain quality and shelf life.
