    Exogenous Selenium Mitigates Salt Stress in Soybean by Improving Growth, Physiology, Glutathione Homeostasis and Antioxidant Defense

    Hesham F. Alharby1, Mirza Hasanuzzaman2,*, Hassan S. Al-Zahrani1, Khalid Rehman Hakeem1

    Phyton-International Journal of Experimental Botany, Vol.90, No.2, pp. 373-388, 2021, DOI:10.32604/phyton.2021.013657

    Abstract The mechanism of selenium (Se)-induced salt tolerance was studied in moderately sensitive soybean (Glycine max L.) plants. To execute this view, soybean plants were imposed with salt stress (EC 6 dS m−1 ) applying NaCl. In other treatments, Se (0, 25, 50 and 75 µM Na2SeO4) was sprayed as co-application with that level of salt stress. Plant height, stem diameter, leaf area, SPAD value decreased noticeably under salt stress. Altered proline (Pro) level, together with decreased leaf relative water content (RWC) was observed in salt-affected plants. Salt stress resulted in brutal oxidative damage and increased the content of H2O2, MDA… More >

    Effects of Different Selenium Application Methods on Wheat (Triticum aestivum L.) Biofortification and Nutritional Quality

    Yong Liang1, Yuexing Chen2, Dong Liu1, Jianping Cheng3, Gang Zhao1, Tzion Fahima4, Jun Yan1,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 423-435, 2020, DOI:10.32604/phyton.2020.09339

    Abstract Mineral nutrient malnutrition, especially deficiency in selenium (Se), affects the health of approximately 1 billion people worldwide. Wheat, a staple food crop, plays an important role in producing Se-enriched foodstuffs to increase the Se intake of humans. This study aimed to evaluate the effects of different Se application methods on grain yield and nutritional quality, grain Se absorption and accumulation, as well as 14 other trace elements concentrations in wheat grains. A sand culture experiment was conducted via a completely randomized 3 × 2 × 1 factorial scheme (three Se levels × two methods of Se application, foliar or soil… More >

    High fluorine and other associated trace elements in waters from the south of the Pampean plain

    Espósito ME1, ME Sequeira2, JD Paoloni3, MC Blanco4, N Amiotti1

    Phyton-International Journal of Experimental Botany, Vol.82, pp. 35-44, 2013, DOI:10.32604/phyton.2013.82.035

    Abstract We investigated the levels of F and its relationship with As, B and V in ground and surface waters of the southern Pampas, where cases of dental and skeletal fluorosis, and arsenic in hair and urine samples have been detected in the rural population. Eating vegetables and cereals grown in irrigated areas with excessive fluoride may increase the risk of fluorosis due to the addition of the extra F contributed from other sources such as drinking water. Moreover, if these elements exceed the tolerance of crops produce toxicity and, like salinity, they decrease the potential crop yield. Within an area… More >

    Trace Elements in the Soil-Plant Systems of Copper Mine Areas-A Case Study From Murgul Copper Mine From the Black Sea Region of Turkey

    Munir Ozturk1,*, Volkan Altay2, Mahir Kucuk3, Ibrahim Ertuğrul Yalçın4

    Phyton-International Journal of Experimental Botany, Vol.88, No.3, pp. 223-238, 2019, DOI:10.32604/phyton.2019.07446

    Abstract This study presents a case study on the heavy metal analysis of soil and plant samples around the Murgul copper mine, one of the first and most important mining areas in Turkey. An attempt has been made to investigate the status of trace elements like Al3+, Fe2+, Cu2+, Zn2+, Pb2+, Ni2+, Co2+ and Cd2+ in soils and plants. The sampling localities were taken from 500 m, 600 m, and 1000 m altitudes around the factory and at 1400 m in the forest zone. The aboveground parts and foliage ash of Silene compacta, Tussilago farfara, Smilax excelsa, Rhododendron ponticum, R. luteum,… More >
