Potential antagonist Zn effect on faba bean (Faba vulgaris m.) contaminated by Pb and Cd / Antagonistyczny wpływ Zn na bób (Faba vulgaris m.) zanieczyszczony Pb i Cd

Abstract

Faba bean (Faba vulgaris M.) is one of the most important crops in most parts of the world including Africa, Asia and Latin America. Major producers of the Faba bean are China, Ethiopia, France and Egypt. The nutritional value of a faba bean is high [Gnanasambandan et al. 2012] and in some areas it is considered to be superior to peas or other grain legumes [Crépon et al., 2010]. Faba bean (Faba vulgaris M.) seeds are rich in protein and starch [Chaieb et al. 2011]. Of the legumes, the faba beans in fresh condition contain most fiber. In bean seeds, the content of lysine and limiting amino acids as methionine and threonine is very favorable. Bean seeds contain a factor that aggravates the retention of Zn and Fe [Gálik et al. 2011]. Faba beans are also grown for green manure and can significantly enhance yields of cereals or other crops [Wani et al. 1994]. Local environmental conditions have influence on the quantitative and qualitative parameters of faba beans [Al-Barri, Shtaya 2013]. Heavy metals occur in the soil in various concentrations and forms. Heavy metals affect plants as a stress factor. Cadmium, lead and Potential antagonist Zn effect on faba bean (Faba vulgaris m.) contaminated by Pb and Cd

Antagonism between lead and zinc ions in plants

“…A similar relation has been noted by Symeonidis and Karataglis (Symeonidis and Karataglis 1992) in the studies of interactions between the metals in Holcus lanatus L. The antagonistic effect of Zn on Pb was also observed in Faba vulgaris Moench (Bystrická et al 2013). Reduction of lead content to 0.61 ± 0.17 μg/g was due to the presence of zinc in an amount of 80 μg/g.…”
