The above facts indicated that silicon accumulation in the rice leaf sheath inside, the leaf surface and the sclerenchymatous cell, played the physical barrier role, delayed the hypha of sheath blight expansion.5、Analysing the physiological and biochemical mechanism of the resistance to rice sheath blight improved by silicon application in several respects.(1) After being inoculated with R.solani, O2 and POD activities disordered, CAT activities obviously declined. 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.

说明硅在水稻叶鞘内侧、叶表和厚壁细胞积累，起到了物理屏障的作用，延缓了纹枯病菌的扩展。5、阐明了施硅增强水稻抗纹枯病的生理生化机制(1)接种纹枯病菌后，两个水稻品种91SP和Lemont的叶鞘和叶片超氧阴离子自由基O2性紊乱，CAT活性明显下降；抗病品种91SP叶鞘和叶片施硅处理的O2产生速率小于缺硅处理，叶鞘和叶片MDA含量在接种第3 d后显著低于缺硅处理，叶鞘SOD、POD、CAT活性在接种1 d后一直显著高于缺硅处理，叶片SOD、POD、CAT活性在接种3 d后显著高于缺硅处理；感病品种Lemont叶鞘和叶片施硅处理的O2产生速率、MDA含量始终显著小于缺硅处理，SOD、POD、CAT活性始终显著大于缺硅处理。

The research activities were briefly highlighted as follows: They were yield nurseries, observational nurseries, tolerance/resistance screening nurseries (cold, drought, salt/acid, blast. bacterial leaf blight, rice tungro virus, brown planthopper and white-backed planthopper resistances).
