Impact of laundry waste water on growth and biochemical characteristics of Vigna mungo L.

Resumo

A pot culture experiment was conducted to study the effect of laundry waste water on seedling growth of Vigna mungo, L. The laundry waste water were collected near Chennai industrial area and their results have been estimated at different concentration of laundry waste water ( 10 , 25. 50 ,75 and 100%). The results showed that the application different concentration of laundry waste water at 30 th days treatment, as resulted significantly decreased of Vigna mungo,L compared with control. But the laundry waste water affected at 30 th day the plants of Vigna mungo L. seedling growth of shoot length, root length, fresh weight, dry weight , Vigor index and biochemical content viz pigment content and carbohydrates, protein was significantly
decreased compared with control. The laundry waste water effect leads to decrease the various growth parameters such as seedling growth of the root and shoot. The reduction in all the growth characteristics and biomass accumulation was parallel to decrease in carbohydrate, protein and nucleic acid content of the leaf and an increase in the anthocyanin, L-proline, peroxidase
catalase and leaf nitrate activity. Laundry waste water treatment should follow the treatment methods and that treated water to use and increases the soil fertility and the high yielding of crop production. The waste water on proper dilution can be also be materialized as cash by proper sale of the product thus the review fresh up the idea of motility of waste material.
