Seed Germination Test Triplicates of selected 25 seeds of Sorghum bicolor were spread on two layers of filter paper in 11- cm Petri dishes. These plates were treated with different concentrations Al Cl3 solution (250, 500 µM AlCl3, 250 µM Al + 250 µM SA and 500 µM Al + 250 µM SA) and Petri dishes were incubated in a grown chamber at 25ºC and 12 h photoperiod. The seeds were considered as germination when radical emerged 1mm and germination was calculated in Percentage. Measurement of Fresh and Dry weights of Fresh weights (F.W) of Al treated were measured immediately after harvesting. Dry weights (D.W) were measured after oven-drying of the seedling sample or 48hr at 1050C.
