Effect on Amylase Activity and Growth Paramaters Due to Metal Toxicity of Iron, Copper and Zinc

Nidhi Mittal, Prachi Vaid, Avneet Kaur

Abstract :

 Increasing contamination and widespread accumulation of heavy metals in soil has become a major concern due to their adverse effect on plant growth and metabolism. Taking this account, an attempt was 

made to study the effect of 50 mM concentration of CuSO4, FeSO4 and ZnSO4 on the root/shoot length, protein content, enzyme activity (α–Amylase) in Vigna Radiata. There was significant decrease in germination and root/shoot length 
in seeds treated with CuSO4, FeSO4 and ZnSO4 as compared to controls. The root/shoot length decreased more 
significantly in the presence of CuSO4 (p<0.0001), ZnSO4 (p<0.0003) as compared to FeSO4 (p<0.003). Significant 
decrease in protein content has been found in Vigna Radiata when treated with CuSO4 and ZnSO4 (p<0.0001). However, there was no significant decrease in protein content when treated with FeSO4. There was significant decrease in 
α–amylase enzyme activity in seeds treated with of CuSO4, FeSO4 and ZnSO4 as compared to controls (p<0.001).
