Germination of seeds is the first physiological evolution affected by various metals (Shankar et al., 2005). One of the Al ion form Al3+ inhibits the seed germination rate at different concentrations in white spruce (Nosko et al., 1988), in pigeon pea (Narayanan and Syamala, 1989) and in wheat (Lima and Copeland, 1990). Different concentrations of Arsenic was inhibited the Seed germination rate and seedling growth of in rice (Abedin and Meharg, 2002). In our study seed germination rate was decreased along with increasing concentration of Aluminium and SA treatment improved the seed germination rate against Al (Fig. 1). These seed germination may improve after SA treatment due to the induction of seed germination of physiological process such as hydrolysis, imbibitions, enzymes activation and protrusion according to (Farooq et al., 2008; Sedghi et al., 2010 and Farooq et al., 2009). The root and shoot length were decreased with increased concentrations of Al by entering in to cytosol of cells and alter the metabolic process after immediate exposure of seedlings to Al (Vazquez et al., 1999; Silva et al., 2000; Sneller et al., 2000 and Abedin and Meharg, 2002). Root growth inhibited plants cannot absorb any nutrients it resulted plants completely decreased its biomass (Mitchell and Barr, 1995). There are some reports are clearly saying that After Al treatment initially Al inhibit the root expansion and elongation behind the cell division (Frantzios et al., 2001). Many researchers investigated the inhibition of seed germination rate, root and shoot lengths and fresh and dry weights up on Al treatment in different plant species (Yang et al., 2007 and Panda et al., 2009).
