The effects of Cr and Co supplied either individually or mixed together in the nutrient solution on seed germination, enzyme activities, photosynthesis, metabolic products, and yield were investigated. Cr and Co reduced germination percentage only at the highest concentration used but markedly decreased radicle growth which might be attributed to depressive effect of Cr and Co on the activity of amylases and subsequent transport of sugars to the embryo axes. Protease activity, on the other hand, increased with the metal treatment. The highest concentration (10(-2) M) tested of both metals was harmful on plant growth, while the low and moderate concentrations (10(-6) and 10(-4) M) enhanced the contents of chlorophylls and sugars, and activity of Hill reaction. Fresh mass of the produced pods increased at low and moderate concentrations of Cr and at Cr+Co treatment, but decreased in plants treated with Co.
