Abstract
Industrial waste water and sewage water is extensively used to irrigate various crops in Karachi. The research was conducted to evaluate the effect of textile industrial waste water, on morphological and biochemical activity of mung bean seedlings as it is composed of various heavy metals. Mung bean genotype ‘Ramzan’ was used as a test material. Seeds were imbibed in deionized water for 12 h, germinated in Petri dishes for 24 h in deionized water. Treatment of various concentrations of textile industrial waste water (10, 50 and 100%) along with control (0%), was given till 72 h. A decrease in seedling length was observed in treated samples as compared to control with more decrease as the concentration of waste water was raised. The amount of soluble proteins was nonsignificantly increased in low concentrations (10 and 50%) as compared to control. However at high concentration (100%), there was significant reduction in mean protein content. Various abiotic stresses like metal stress is able to cause lipid peroxidation which can be detected by Malandialdehyde (MDA) content. We found that there was more accumulation of MDA as well of proline in treated samples in concentration dependent manner.
