O2 producingvelocity in 91SP\'s leaves and leaf sheaths of Si+ rice plants were lower than those of Siriceplants, MDA content in leaves and leaf sheaths of Si+ rice plants were lower thanthose of Si- rice plants significantly in three days after inoculating, SOD、POD、CATactivities in leaf sheaths of Si+ rice plants were higher than those of Si- rice plantssignificantly in one day after inoculating, SOD、POD、CAT activities in leaves ofSi-treatment were higher than those of Si- rice plants significantly in three days afterinoculating. O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.
