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.

Highlights

Copper is a widespread pollutant of the industrial world originating from electric power plants, metal smelting plants, cars, agrochemicals such as pesticides, and sewage sludge (Verkleij, 1994)
Null Hypothesis: There is no significant effect of CuSO4 on growth of Brassica juncea Alternate Hypothesis: There is significant effect of CuSO4 on growth of Brassica juncea
The effect of CuSO4 had adverse effect on the growth of plants as we can see the difference in following Table 1 as the concentration of CuSO4 increased the growth has significantly decreased comparing to control

Summary

Introduction

Copper is a widespread pollutant of the industrial world originating from electric power plants, metal smelting plants, cars, agrochemicals such as pesticides, and sewage sludge (Verkleij, 1994). A major part of the studies of the effects of copper on plants has been conducted in solution cultures. Such studies provide relative toxicities of different toxicants, but results are difficult to extrapolate to natural growth media because of the high affinity of copper to chelate strongly to the organic fraction of the soil and because this chelation is pH dependent (Adriano, 1986). Toxic concentrations of copper affect plants in many ways.
