“…In Catharanthus roseus L. cell suspension culture, Mg content was not affected by Se treatment (Arvy et al, 1995). Reductions in Se and sulfur level did not affect carotenoid pigments such as lutein and beta carotene (Kopsell et al, 2000). Stomata conductance and internal CO 2 concentration of stomata decreased by increasing Se levels and no significant change was observed in the photosynthetic rate.…”

“…Drought stress damages with applying Se decreased (Hasanuzzaman and Fujita, 2011). In tomato plants planted in soil with the high levels of mercury (Hg), Hg accumulation was prevented by Se application (Kopsell et al, 2000). By Se application on cucumbers under cold stress, antioxidant activity increased and lipid peroxidation decreased (Liu et al, 2009).…”

Selenium (Se) is an essential element for human and livestock with antioxidant and anticancer characteristics. Although Se is not an essential element for plants, it has been reported that it can improve plant growth. This experiment was conducted at the Isfahan University of Technology in winter 2010. The experiment was factorial based on a completely randomized design (CRD) with 4 replications. Se was added to nutrient solution in 4 concentrations 2, 4, and 6 mg/l sodium selenite (Na 2 SeO 3 ). Root volume, fresh and dry weights of shoots and roots, number and weight of fruits, chlorophyll content and photosynthesis traits (photosynthesis rate, stomata internal carbon dioxide (CO 2 ) concentration, stomata conductance) were measured. Results showed that Se increased root dry weight. Fresh and dry weights of shoot increased in the 2 mg/l Se treatment and decreased at the higher level of Se. Chlorophyll content and photosynthesis rate were not affected by Se. Stomata internal CO 2 concentration and stomata conductance decreased by Se addition. Overall, Se at 2 mg/l application rate was effective in some physiological characteristics of cucumber. Keywords

“…Similarly to other heavy metals, Se can modify the uptake and accumulation of macro and micro-nutrients which are important for plant metabolism (Kopsell et al, 2000;Pazurkiewicz-Kocot et al, 2003;Tennant and Wu, 2000). Kostopoulou et al (2015) reported various changes in macronutrient concentrations of Se enriched plants, while the micronutrient content decreased significantly.…”

The objective of this study was to examine the combined effects of selenium (Se) enrichment and water stress on the accumulation of available macro-and micronutrients in Melilotus officinalis L. aerial parts. Plants of M. officinalis were subjected to three levels of Se addition (0, 1 and 3 mg Se L -1 water) and to two water treatments: a) full irrigation and b) limited irrigation (water stress). The above ground biomass (stems and leaves) was analyzed for Se, potassium (K), sodium (Na), magnesium (Mg), iron (Fe), copper (Cu), calcium (Ca), manganese (Mn) and zinc (Zn). Se addition differentially affected the K, Mg and Ca content of M. officinalis aerial parts, while it led to the reduction of the micronutrients Cu, Fe and Mn. Water stress resulted in the increase of K, Na, Mg, Ca and Cu, and to the decrease of the Fe, Zn and Mn content. An interaction between selenium addition and water treatment was more notable for Ca and Mg, which decreased under water stress at low Se level and for Zn and Cu, which increased under water stress at high Se level. According to our findings, Seinduced increased accumulation of some inorganic ions in the aerial parts of this species under water stress conditions could serve as a means to alleviate the adverse impact of water deficit on important metabolic processes, enhancing M. officinalis tolerance to water stress.

“…Total Se content in soybeans is generally very low, ranging from 0.07 to 0.20 mg/kg (MacLeod and Gupta, 1995). Whereas accumulation of Se was found in wheat (Grieve et al, 1999) and plant tissues of Astragalus bisulcatus (Duckart et al, 1992) and Brassica oleracea (Kopsell et al, 2000) by increasing sodium selenate concentrations in the substrate, grain Se concentration in soybeans was increased by increasing Se concentration in the planted seeds (Gupta and MacLeod, 1999). Selenium uptake by plants depends on many factors including substrate characteristics such as total salinity and the speciation of salt ions (Brown and Shrift, 1982;Läuchli, 1993;Wu, 1998).…”

A greenhouse study was conducted to determine the effects of irrigation waters differing in salt composition on growth characteristics, salt ion and selenium (Se) accumulation, and distribution in plant components of the soybean (Glycine max L. Merr.) cultivar "Manokin." Plants were grown in sand cultures and irrigated with isoosmotic solutions containing (1) Cl − as the dominant anion, or (2) a mixture of salts containing equal molar amounts of SO 2− 4 and Cl − . Six treatments of each salinity type were imposed. Electrical conductivities of the irrigation waters ranged from 2.1 to 13.0 dSm −1 . Selenium (1 mg · L −1 , 12.7 µM) was added to all irrigation waters as Na 2 SeO 4 . Regardless of salinity type, soybean plants were generally taller under the low-salinity treatments in early vegetative stages of growth. Towards the end of vegetative stages and until final harvest, higher values of plant height, leaf area, and shoot dry weight were found at the intermediate salinity levels (5.0 and 9.2 dS m −1 ), and higher salinity in general led to increased soybean leaf chlorophyll on a unit-area basis. Shoot-to-root ratios decreased with increasing chloride salinity, while the ratios remained nearly constant under the sulfate salinity treatment. Plant uptake and accumulation of salt ions (Ca 2+ , Mg 2+ , Na + , Cl − ), K + , total phosphorus (p), and total sulfur (s) were generally not related to the type of salinity, except total S, where higher concentrations were found in leaves, stems, and roots in the sulfate than under the chloride salinity treatment. Selenium concentration in leaves and seeds was about 4 mg kg −1 at final harvest when irrigated with the sulfate-based saline waters. Under the chloride salinity treatment, Se level was found to be about three times higher in leaves and five times higher in seeds. In conclusion, different solution concentrations of SO 1073This article is a U.S. government work, and is not subject to copyright in the United States. D. Wang et al.decreased with increasing chloride salinity, high-sulfate salinity reduced Se uptake by "Manokin" soybean.
