“…Selenium has also been proved to delay postharvest losses affecting ethylene production in different produce, such as broccoli, tomato, and in some leafy vegetables . In peach and pear, foliar and fruit selenium spraying delayed the reduction of flesh firmness and the onset of fruit ripening, thus improving the fruit shelf‐life .…”

BACKGROUND: Selenium (Se) enrichment of plants seems effective in enhancing the health-related properties of produce and in delaying plant senescence and fruit ripening. The current study investigated the effects of Se on tomato fruit ripening. Tomato (Solanum lycopersicum L.) plants were grown in hydroponics with different Se-enriched nutrient solutions. Se, as sodium selenate, was added at a rate of 0 mg L −1 (control), 1, and 1.5 mg L −1 . RESULTS: Selenium was absorbed by roots and translocated to leaves and fruit. Enrichment with Se did not significantly affect the qualitative parameters of fruit at commercial harvest; instead it delayed ripening by affecting specific ripening-related processes (respiration, ethylene production, color evolution) during postharvest. In the current experiment 100 g of tomato hydroponically grown with a 1.5 mg Se L −1 enriched solution provided a total of 23.7 g Se. Selenium recommended daily intake is 60 g for women and 70 g for men; thus the daily consumption of 100 g of enriched tomato would not lead to Se toxicity but would provide a good Se diet supplementation. CONCLUSIONS:The cultivation of tomato plants in a Se-enriched solution appeared effective in producing tomato fruit with improved performance during storage and postharvest shelf life, and also with greater potential health-promoting properties. Statistical analysisData were subjected to one-way analysis of variance (ANOVA) with Se treatments as variables. The means were separated using the least significance difference (LSD) (P < 0.05). Statistical analysis was performed using Statgraphics Plus 5.1.

“…Selenium can also slow down softening of ripe fruits. With its antioxidant action selenium can reduce the production of ethylene in plants and thus slows down the senescence and prolongs the life of the fruits (Lv et al, 2017;Hu et al, 2003;Pezzarossa et al, 2012;Puccinelli et al, 2017). For selenium was found to be able to protect the plants against abiotic stress such as cold, drought and an increased content of heavy metals in the soil and biotic stress such as pathogens and herbivores (Gupta & Gupta 2017;.…”

“…Selen lahko vpliva na kakovost sadja in zelenjave. Obravnavanje rastlin brokolija s selenom je imelo pozitiven učinek na ohranjanje senzoričnih lastnosti in kakovosti brokolija, saj je vplival na zmanjšanje respiratorne učinkovitosti in proizvodnjo etilena v brokoliju in tako upočasnil zorenje brokolija in mu na ta način podaljšal obstojnost (LV et al 2017). Selen je pri zelenem čaju vplival na povečanje pridelka, skupne vsebnosti aminokislin in vsebnost C vitamina (Hu et al 2003).…”

IZVLEČEK Selen v vodnih in kopenskih rastlinahTako vodne kot kopenske rastline so sposobne privzemati selen iz okolja. Sposobnost privzema selena se med vrstami in skupinami rastlin razlikuje. Rastline iz tal privzemajo selen prvenstveno v obliki selenata, ki ga nato pretvorijo v selenit in selenove-aminokisline, kot sta selenometionin in selenocistein. Zaradi različnih antropogenih dejavnikov in predvsem dejavnosti človeka, se povečuje obremenjenost vodnih virov s selenom. Vodne rastline, ki so sposobne privzemati večje količine selena iz vode, lahko uporabimo za čiščenje s selenom obremenjenih umetno ustvarjenih in naravnih vodnih teles. Služijo lahko tudi kot bioindikatorji obremenjenosti s selenom. Selen ima pri kopenskih rastlinah pozitiven učinek na rast rastlin in dozorevanje semen. Pozitivni učinki selena se odražajo tudi v večji zaščitenosti rastlin pred ultravijoličnim sevanjem, mrazom, sušo in zmanjšanim privzemom težkih kovin iz tal ter večjo zaščitenostjo rastlin pred patogeni in rastlinojedci. Prisotnost selena v kmetijskih rastlinah vpliva na zmanjšanje proizvodnje rastlinskega hormona etilena, ki je odgovoren za senescenco in zorenje plodov. Selen tako lahko prispeva tudi k daljši obstojnosti plodov. Rastline, ki imajo večjo sposobnost za privzem selena iz tal, lahko uporabimo tudi za fitoremediacijo s selenom onesnaženih tal. Poznavanje načinov privzema in akumulacije selena v vodne in kopenske rastline je ključno za razumevanje kroženja selena v okolju.Ključne besede: selen, vodne rastline, kopenske rastline ABSTRACT Selenium in water and in terrestrial plantsAquatic as well as terrestrial plants are able to uptake selenium from the environment. The ability to uptake selenium differs between plants. Plants uptake selenium primarily as a selenate, which is then converted into selenite and selenium-amino acids, such as selenomethionine and selenocysteine. Due to various anthropogenic factors and man's activity, pollution of water sources with selenium is increasing. Aquatic plants that are capable of absorbing selenium from water can be used for purifying waters contaminated with selenium in artificial and natural water bodies. In water bodies they can also be used as bioindicators of pollution with selenium. Selenium has a positive effect on plant growth and maturation of seeds in terrestrial plants. Positive effects of selenium are also shown in the increased protection of plants against ultraviolet radiation, cold, drought and reduced uptaking the heavy metals from the soil, and greater protection of plants against pathogens and herbivores. The presence of selenium in agricultural plants lowers the production of plant hormone -ethylene, which is responsible for senescence and ripening of the fruits. Selenium thus can also contribute to longer stability of plant fruits. Plants that have greater ability to uptake selenium from the soil can also be used for phytoremediation with selenium contaminated soils. Knowledge of the techniques of absorption and accumulation of selenium in aquatic and terr...
