Effects of NaCl on plant growth and antioxidant activities in fenugreek (Trigonella Foenum Graecum L.)

Abstract

Fenugreek is used as a spice, vegetable and a important medicinal crops cultivated throughout the world. Since antioxidant properties have been linked to health benefits of natural products, such properties were studied salt concentrations (0, 50, 100,150 and 200 mM NaCl) effect on plant growth mineral contents composition, antioxidant responses and phenolilc contents. Results showed a reduction of dry weights of leaves stems and roots growth. These changes were associated with decreased in water content, K + and Ca 2+ concentrations and a highly increased in Na + and Clcontents in different organs. Catalase, guaiacol peroxidase activities and total phenolic content significantly increased in fenugreek leaves. Data reported here revealed the variation of phenolic compound contents at different organs in the presence of salt, who suggested the use of Fenugreek in commercial and economic applications.

Sargassum wightii Aqueous Extract Improved Salt Stress Tolerance in Abelmoschus esculentus by Mediating Metabolic and Ionic Rebalance

“…Terpene is a class of secondary metabolites having antioxidant properties proven in different in-vitro assays (Aziz et al, 2018). Tannins have been proven to have a significant impact on plants in terms of inducing ROS-scavenging qualities under stress, and high tannin levels in plants induced by seaweed application improve the uptake of potassium ions, which has a positive influence on plant development and salt stress reduction (Baatour et al, 2018). SAE treatment had a significant impact on the terpene and tannin levels of A. esculentus plants, according to current findings.…”

Teores E Acúmulos De Nutrientes Em Mudas De Maracujazeiros Sob Salinidade Hídrica E Uso De Urina De Vaca

“…No tocante ao estado nutricional, em condições de exposição salina, ocorrem tendências de que as plantas apresentem decréscimos nos teores foliares de macronutrientes (SCHOSSLER et al, 2012). Para Olfa et al, 2018) isto pode estar relacionado ao excesso de sais solúveis na zona radicular, com redução na matéria seca caulinar e radicular em razão de menor absorção de água, que pode restringir a absorção de alguns elementos pelas plantas, principalmente K + e Ca 2+ , acarretando, em muitos dos casos, em deficiências nutricionais.…”
