Current study presents the effect of irrigation with different concentrations (20, 40, 60, 80 and 100%) of untreated and treated brewery-distillery effluent on germination behaviour of marigold (Tagetes erecta L. var. Pusa Basanti). The 100% untreated effluent showed acidic pH (4.80) and higher values of BOD (1500.00 mg l(-1)), COD (4000.00 mg l(-1)), chloride (1742.20 mg l(-1)), TSS (900.00 mg l(-1)) as compared to that of treated effluent. Tagetes seeds were exposed to different concentrations of effluent and the results revealed maximum values of germination parameters viz., percent germination, peak value, germination value, germination index, speed of germination and vigour index at 20% untreated and 60% treated effluent concentrations, whereas the values for negative germination parameters viz., delay index, germination period and percent inhibition were minimum at 20% untreated and 60% treated effluent concentrations.
当前研究展示了用不同浓度（20%、40%、60%、80%和100%）的未处理和处理后的啤酒厂-酿酒厂废水灌溉对万寿菊（Tagetes erecta L. var. Pusa Basanti）发芽行为的影响。与处理后的废水相比，100%的未处理废水呈现酸性pH值（4.80）以及更高的生化需氧量（BOD）值（1500.00毫克/升）、化学需氧量（COD）值（4000.00毫克/升）、氯化物含量（1742.20毫克/升）、总悬浮固体（TSS）含量（900.00毫克/升）。将万寿菊种子暴露于不同浓度的废水，结果显示，在20%的未处理废水和60%的处理后废水浓度下，发芽参数的最大值，即发芽率、峰值、发芽值、发芽指数、发芽速度和活力指数出现；而在20%的未处理废水和60%的处理后废水浓度下，负发芽参数的值，即延迟指数、发芽周期和抑制率最低。
