Heavy metals are a very
important abiotic stress factors that can induce different response mechanisms
in plants. These response mechanisms include modifying membrane
compositions, generating small
molecules and free radicals, and altering antioxidant enzyme activities. In
this study, we aimed to determine the effect of lead (Pb), an important heavy metal, on some growth
parameters, enzymes, and the content of macro- and micro-nutrients. This
study was launched to determine
the effects of lead (0, 25, 50, 75, 100 mg L-1) on fenugreek’s (Trigonella foenum-graecum L.) growth parameters and biochemical responses in a fully controlled aeropon- ic climate chamber.
Growth, biochemical enzyme activities and the content
of macro- and micro-nutrients
of fenugreek plants changed under heavy metal stress. In the study, a decrease occurred in parameters such as the plant
height (cm), root length (cm), root and stem fresh weight (g), leaf weight (g) and leaf number (number).
There were increases
in malondialdehyde (MDA) and ascorbate peroxidase (APX)
enzymes. There was a decrease in the content of mine- rals (Ca, K,
Mg, Na, Cu,
Ni, Fe, Zn,
Mn, Cr, Ni, Se and
Cd) in leaves,
stem and root
parts of fenugreek plants. In
this study, lead tolerance conditions, the plant content of macro- and micro-nutrients and enzyme activity
values of this plant were determined.
