In this study Sanganer town, Jaipur was selected as study area. The plants of Lycopersicon esculentum var. K 21(Tomato) treated with 20 and 30% textile wastewater were analyzed for metal accumulation, growth and biochemical parameters at per, peak and post flowering stages. Findings of the study revealed that chlorophyll content was most severely affected with the increase in metal concentration. Total chlorophyll content showed a reduction of 72.44% while carbohydrate, protein and nitrogen content showed a reduction of 46.83, 71.65 and 71.65% respectively. With the increase in waste water treatment the root and shoot length, root and shoot dry weight and total dry weight were reduced to 50.55, 52.06, 69.93, 72.42, 72.10% respectively. After crop harvesting, the fruit samples of the plants treated with highest concentration of textile waste water contained 2.570 mg g(-1)d.wt. of Zn, 0.800 mg g(-1) d.wt. Cu, 1.520 mg g(-1) d.wt. Cr and 2.010 mg g(-1) d.wt. Pb.
在本研究中,斋浦尔的桑加纳镇被选为研究区域。对用20%和30%纺织废水处理的番茄品种K 21(番茄)植株在开花前期、开花高峰期和开花后期的金属积累、生长及生化参数进行了分析。研究结果表明,叶绿素含量受金属浓度增加的影响最为严重。总叶绿素含量降低了72.44%,而碳水化合物、蛋白质和氮含量分别降低了46.83%、71.65%和71.65%。随着废水处理浓度的增加,根长、茎长、根干重、茎干重和总干重分别降低至50.55%、52.06%、69.93%、72.42%和72.10%。作物收获后,用最高浓度纺织废水处理的植株果实样本中锌含量为2.570毫克/克干重,铜含量为0.800毫克/克干重,铬含量为1.520毫克/克干重,铅含量为2.010毫克/克干重。
