Studies revealed that, control treatment showed constantly higher seed germination while the concentrations of Cobalt, Nickel and Lead chloride reported negative impact on seed germination of Acacia nilotica. In case of Cobalt chloride, overall mean seed germination was 19.10 per cent at 5 DAS and 62.75 per cent at 19 DAS. The highest germination was recorded in control (88.15%) followed by 100 ppm (85.56%), 200 ppm (73.33%) and 500 ppm (65.56%) at 19 DAS while in concentrations of Nickel chloride, germination of seeds started from 5 DAS in all the cases except 2000 ppm where it was observed from 14 DAS with 16.67 per cent germination. Control treatment showed the higher germination percentage as compared to other treatments during 5 to 19 DAS. Germination in concentrations of Lead chloride was recorded on 5 DAS in all the treatments except 2000 ppm concentration where germination was recorded at 14 DAS. The mean germination of 15.62 per cent was recorded at 5 DAS and 56.40% at 19 DAS. Maximum seed germination was obtained in control (88.15%).
