Effect of Industrial Effluents on Seed Germination and Early Growth of Cicer arientum

Sofia Nawaz, Syeda Maria Ali and Azra Yasmin

ABSTRACT

The aim of this study was to determine the effects of different effluents on seed germination and early growth of plants. Water samples were collected from three different industries of Rawalpindi, which were Koh-e-Noor textile mill (KNM), Marble Industry (MI) and Attock Refinery Limited (ARL). Two different varieties of Cicer arientum (P-91 and P-2000) were selected to grow in these effluents. Physicochemical parameters (pH, temperature, Dissolved Oxygen (DO), conductivity, turbidity, Total Dissolved Solids (TDS), Total Suspended Solids (TSS) etc.) of these samples were analyzed. Both varieties were grown in different dilutions of effluents. With t he increase in effluent concentration, growth of plants was found more affected in Koh-e-Noor mill effluent while, less effect was seen in Marble and ARL effluents. Increase in root and shoot lengths were observed in these effluents at different concentrations. Fresh weight was less in Koh-e-Noor mill effluent as compared to control while in other two effluents both increases and decreases in dry weight were observed. Dry weights of plants were greater in most of the treatments. Variety P-91 was more tolerant as compared to P-2000.
