Abstract
In this study, calcium silicate and sodium silicate were added to OM7347 rice seedlings grown in artificial aluminum toxicity (AlCl3) conditions. This study was carried out through two experiments to evaluate the effect of sodium silicate and calcium silicate on aluminum resistance in rice planting stage OM7347. Experiment 1, theeffects of aluminum were evaluated at three different levels (AlCl3 50, 100 and 150 mM) on plant growth. Experiment 2, sodium silicate and calcium silicate were added with a concentration of 200 mg/L to aluminumtoxic medium (AlCl3 50 and 100 mM) to evaluate the aluminum poisoning improvement effect of Si compounds. Experimental results showed that rice seedlings were very sensitive to aluminum, and a concentration of 50 mM reduced rice seedlings development. AlCl3 caused lower pH values, decreased chlorophyll a content, plant height and root length were poorly developed resulting in low fresh biomass. In addition, aluminum presentmade root cells lose their integrity and lipid peroxidation occured. However, when sodium silicate and calcium silicate were added to the cultured solution, the pH values of the solution increased, improved plant growth such as shoot height, root length, fresh biomass and especially reduced aluminum toxicity on root morphology of rice seedlings indicated by less of lipid peroxidation and maintained root cell integrity. Silicon supplementsprevented aluminum accumulation in roots and improved secondary root system, root branching.
