Melatonin supplementation combats nickel-induced phytotoxicity in Trigonella foenum-graecum L. plants through metal accumulation reduction, upregulation of NO generation, antioxidant defence machinery and secondary metabolites.

Nickel (Ni) at a toxic level (80 mg kg of soil) adversely affects the crop performance of fenugreek (Trigonella foenum-graecum L.). Melatonin (MEL), a potent plant growth regulator, is ascribed to offer promising roles in heavy metal stress alleviation.

Silicon dioxide nanoparticles suppress copper toxicity in Mentha arvensis L. by adjusting ROS homeostasis and antioxidant defense system and improving essential oil production.

Copper (Cu) is an essential micronutrient for plants; however, the excessive accumulation of Cu due to various anthropogenic activities generates progressive pollution of agricultural land and that causes a major constraint for crop production. Excess Cu (80 mg kg) in the soil diminished growth and biomass, photosynthetic efficiency and essential oil (EO) content in Mentha arvensis L., while amplifying the antioxidant enzyme's function and reactive oxygen species (ROS) production.

Exogenous abscisic acid fine-tunes heavy metal accumulation and plant's antioxidant defence mechanism to optimize crop performance and secondary metabolite production in Trigonella foenum-graecum L. under nickel stress.

Nickel (Ni) contamination of farming soil has become currently a recurring global menace to agriculture crop productivity. The purpose of the present study was to investigate the putative contributions of abscisic acid (ABA) to extemporize Ni tolerance in Trigonella foenum-graecum L. (fenugreek) plants.

Soil-applied Nickel Generates Differential Responses in Growth, Physiology and Oxidative Metabolism of Fenugreek (Trigonella foenum-graecum L.) Varieties.

This work aims to evaluate the potential of nickel (Ni), an essential micronutrient, as an oxidative stress inducer along with associated morphological and biochemical responses in different varieties of fenugreek (Trigonella foenum-graecum L.), a chief economically cultivated crop of India. Varietal differences in crop performance upon exposure to 0, 20, 40, 60 and 80 mg Ni kg soil reflects that Ni applied at 20 mg Ni kg soil offers growth-promoting effects, improved photosynthesis attributes, carbonic and nitrate reductase activities more profound in PEB followed by AFg2, AFg1 and UM185 variety.
