Comparative effect of Nickel and beta-aminobutiric Acid on some Secondary Metabolits of Echium amoenum

Abstract

Article InformationPlants have a wonderful variety of secondary metabolites which may be change due to environmental factors and stress conditions. Considering the importance of Echium amoenum in Iranian traditional medicine, this study aimed to investigate the effect of abiotic stresses on the possibility of further production of secondary metabolites in the plant. In general, according our research findings, betaaminobutyric acid increased growth indexes. Effect of BABA on secondary metabolites was different. BABA increased plant flavonoids but reduced the tannins. Numerous studies have pointed to the stress effects of this material at high concentrations but the concentrations used in this study increased the plant growth. Nickel in applied concentrations had no significant reduction in plant dry weight but increased the photosynthetic pigments. Ni increased plant flavonoids but reduced the tannins. Nickel and beta-aminobutyric acid at low concentrations, is recommended to use for greater production of secondary metabolites in Echium cultivation.

Sodium Nitroprusside Mitigates the Inhibitory Effect of Salt and Heavy Metal Stress on Lupine Yield and Downregulates Antioxidant Enzyme Activities

“…With regards to the effects of heavy metals, we found that treatment with NiSO 4 at 100 mM and 150 mM promoted increases in total phenol and flavonoid contents in the shoots and roots of lupine plants, when compared with the control values. Previous studies have shown significant increases in phenol and flavonoid contents of plants in response to nickel treatment (Rajaei & Mohamadi, 2015) , and it is believed that such increases in turnip (Brassica rapa L.) and lettuce plants grown in heavy metal-enriched soil are defense mechanisms designed to ameliorate the oxidative damage caused by heavy metal contamination (Hassanein et al, 2013).…”
