Abstract
Dye
industry effluent was analyzed for physico-chemical characteristics and its
impact on germination and growth behaviour of Pea (Pisum sativum). The
100% effluent showed high pH (10.3) and TDS (1088 mg l-1). The germination
parameters included percent germination, delay index, speed of germination,
peak value and germination period while growth parameters comprised of root
and shoot length, root and shoot weight, root-shoot ratio and number of
stipules. The study showed the maximum values of positive germination
parameters viz. speed of germination (7.85), peak value (3.28), germination
index (123.87) and all growth parameters at 20% effluent concentration while
the values of negative germination parameters viz. delay index (-0.14) and
percent inhibition (-8.34) were found to be minimum at 20% effluent
concentration. The study demonstrated that at lower concentrations the dyeing
industry effluent caused a positive impact on germination and growth of Pisum
sativum.
