ABSTRACT:
The paper presents an investigation conducted in order to study the phytotoxic effects of textile wastewater on germination and early growth of Triticum aestivum. Triticum aestivum belongs to family Poaceae and commonly referred to as common wheat, bread wheat. Sixteen samples were collected from Bagru (Hub of small scale textile industries) Rajasthan and were analyzed for various physic-chemical parameters including pH, TDS, EC, Chloride, hardness etc. the wastewater were rich in hardness, chloride etc with pH ranges from 2.0 to 8.12. Parameters studied in case of o. sativa includes germination percentage, percentage phytotoxicity, Tolerance index, relative length of germinated seedlings, fresh weight and dry weight of seedlings. Germination percentage and seedling growth shows considerable reduction as compared to control with relative germination percentage reducing to 36.66% as compared to control with 100% germination percentage. Similarly the wastewater showed inhibitory effect on seedling growth with minimum length of root up to 1.03±0.1 cm and shoot up to 0.74±0.05 cm in contrast with control with 6.48±0.01 cm root length and 5.65±0.04 cm shoot length. Effluent with lower concentration showed seedling growth higher than the control. The findings indicate that textile wastewater being rich in dissolved solids reduces the energy supply through anaerobic respiration causing retardation of growth and development of seedling. Similarly increase in phytotoxicity percentage and decrease in tolerance index and vigour index was observed. Therefore use of wastewater for irrigation purpose cannot be permitted without treatment.
