Abstract
Copper is one of the heavy metals, although it is an essential microelement through interference with numerous physiological processes, when it absorbed in excess amounts, it can be toxic and induce a number of deleterious effects. A pot experiment was conducted in order to assess the possible effects of Nostoc muscorum (2 g/ kg soil fresh pellets) on the growth and some metabolic activities of Trigonella foenum gracum at 30 and 60 days of growth growing under copper stress. This experimental plant was grown in clay-sandy soil (2:1 W/W) amended either with different concentrations of CuSO4 (0.4, 0.6, 0.8 and 1.0 g/kg soil) or Nostoc mixed with Cu (0.6, 0.8 and 1.0 g/kg soil). Application of Nostoc in a mixture with Cu significantly increased fresh and dry weight of root and shoot, photosynthetic pigments and ctivity at 30 and 60 days of growth when compared with their counterparts of Cu treatment. In addition, the content of K+, Ca2+, P3+ and iron were increased with the exception of a decrease in Cu level at 60 days of growth. On the other hand, the content of starch was significantly decreased at 30 and 60 days of growth. Moreover, the activity of both peroxidase (POD) and superoxide dismutase (SOD) were reduced by applying Nostoc to the soil having different concentrations of Cu.
