Abstract

AlCl3 dissolved in half-strength Kimura B nutrient solution was observed to be less effective in inhibiting root growth of rice seedlings than that dissolved in distilled water. Kimura B nutrient solution is composed of inorganic salts and citrate. Thus, we investigated the influence of inorganic salts and organic acids on AlCl3-inhibited root growth of rice seedlings. It was observed that CaCl2, MgCl2, N aH2PO4, citrate, malate, tartarate, and oxalate were able to reduce AlCl3-inhibited root growth of rice seedlings. Results suggest that the effect of CaCl2, MgCl2, and organic acids on AlCl3-inhibited root growth is mediated through reducing Al level in roots of rice seedlings.
