Effect of CuSO4 on the growth of Brassica juncea L.

Abstract

Seeds of Black Mustard (Brassica juncea) were sowed in a paper cup with copper sulfate at different concentration. This experiment aimed to determine the effect of the variation in concentration of copper sulphate on the germination and growth of seeds of Brassica juncea. We wanted to establish which is the highest concentration of copper that the seeds of Black Mustard can tolerate. Seedlings growth investigation and measurements were made after 5 days. The seed germination rate was low to no for the high concentration and for control that increased dramatically with the decrease in concentration. At high concentration, no growth was seen.
