Abstract

This project was carried out to investigate the effect of pharmaceutical industry effluents on seed germination and seedling growth of some common cultivated crops of Bangladesh. Four varieties of crops such as Okra, Data shak, Ridge gourd, and Black mustard were selected to grow in this effluent. Concentrations used for the effluents in terms of seed germinations were 0%, 25%, 50%, 75% and 100% respectively. The optimum condition of seed germination obtained for Okra, Data shak and Ridge gourd were 25%, 100% and 50% respectively. However, in terms of Black mustard the germination percentage was same in all condition. At lower dilutions the crops exhibited favorable effect on seed germination, seedling growth, shoot length and root length. Among all 100% concentrations of the effluent caused inhibitory effect in terms of all crops except Black mustard. Based on the present investigations, it can be concluded that pharmaceutical effluent which is discharging as waste can be used for irrigation purpose, after proper dilution. Bangladesh J. Sci. Ind.

制药工业废水对孟加拉国一些常见作物种子发芽和幼苗生长的影响

本项目旨在调查制药工业废水对孟加拉国一些常见栽培作物种子发芽和幼苗生长的影响。选择秋葵、大沙、脊葫芦和黑芥菜等四个品种在该污水中种植。就种子发芽而言，废水的浓度分别为0%、25%、50%、75%和100%。结果表明，秋葵种子发芽率为25%，大沙种子发芽率100%，冬瓜种子发芽率50%。然而，就黑芥菜而言，在所有条件下发芽率都是相同的。在较低的稀释度下，作物对种子发芽、幼苗生长、茎长和根长都有良好的影响。在所有100%浓度的流出物中，除黑芥菜外，对所有作物都产生了抑制作用。根据目前的调查，可以得出结论，作为废物排放的制药废水经过适当稀释后可以用于灌溉。孟加拉国科学杂志。Ind.Res.57（1），2022年15月22日
