Soil contamination by heavy metals is a global environmental problem. This
contamination affects agricultural crops in the area concerned. In the present study, chromium,
which is a heavy metal, is evaluated for its diverse effects on seed germination and lateral growth
of fenugreek and lens seeds. A chromium solution was prepared at increasing concentrations:
0, 0.02, 0.04, 0.06, 0.08, 0.1, and 0.2 mg L-1 for the addition of germinating seeds in petri dishes
for ten days. After two days, the germination rate is calculated. For the following days the length
of radicle, stem, and number of leaves are measured. The germination rate of fenugreek varies
between 100 and 73.33% for the control and 0.02 mg L-1 of chromium respectively. However,
the germination rate of the lens varies between 100% for the control and 90% for the
0.02 mg L-1
. The elongation of fenugreek radicle with chromium solutions shows a significant
effect. However, there is no significant difference in the lens at the different concentrations. For
the growth of the fenugreek stalk, it is noticed that the concentration 0.02 shows a length of
2.83 cm compared to their control which is 2.30 cm. Consequently, chromium at 0.02 mg L-1
stimulates growth, but at 0.2 mg L-1
, it inhibits it. For lens the length of the stems shows also a
significant difference compared to their control. So the effect of chromium on germination
parameters depends on their concentrations, as well as on the seed response itself. For our
research the response of fenugreek compared to the lens at the same concentrations is different.
