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 shootweight, 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.
对染料工业废水的物理化学特性及其对豌豆(Pisum sativum)发芽和生长行为的影响进行了分析。100%的废水显示出高pH值(10.3)和总溶解固体(1088 mg l(-1))。发芽参数包括发芽率、延迟指数、发芽速度、峰值和发芽期,而生长参数包括根和茎的长度、根和茎的重量、根冠比和托叶数量。研究表明,在20%废水浓度下,发芽参数的正值(即发芽速度(7.85)、峰值(3.28)、发芽指数(123.87))以及所有生长参数均达到最大值,而在20%废水浓度下,负发芽参数(即延迟指数(-0.14)和抑制率(-8.34))的值最小。该研究表明,在较低浓度下,染料工业废水对豌豆的发芽和生长产生了积极影响。
