Based upon the ecoanatomical method, leaf anatomical characters of eleven populations of six evergreen species (Cyclobalanopsis glauca, C. myrsinaefolia, C. gracilis, Castanopsis sclerophylla, C. eyrei and Lithocarpus glaber) from the eastern subtropical area of China were analyzed and compared with SPSS, DCA and TWINSPAN. The results are: 1. Although the leaf structures of the eleven populations still belong to the mesophyll type, they all express the trend of xerophilization. 2. There are some differences in leaf anatomical characters among populations, species and genera, which occur as the results of their adaptation to different habitats. 3. Different leaf anatomical characters have different variations among populations, species and genera, of which leaf thickness and palisade tissue thickness (considered as ecological adaptation characters) have greater variation than sponge tissue thickness, lower cuticle thickness and lower epidermis thickness (as systematical evolution characters). 4. The leaves of C. sclerophylla and C. glauca with thicker lamina, palisade tissue and cuticle (a multilayered upper epidermis in C. sclerophylla) are thought to better adapt to their dry habitat. The leaves of C. eyrei with thicker sponge tissue, although characterized by a multlayered upper epidermis, adapt to their humid and warm habitat. The leaves of C. myrsinaefolia and C. gracilis characterized by a thinner lamina, a less palisade tissue and a moderate cuticle thickness adapt to the humid and cool habitat in a middle mountain.

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。

Leaves began to shape from the end of March until September, and the growth of young leaves terminated in November. In February or March of the next year, the leaves shot out of the ground. Finally, they withered in May. In addition, 4 phases exist in the process of leaf shaping (buttress forming, primordium, straplike leaf and sheath). At first, the leaf primordium shapes the zonary leaf, and then the plaits are formed at the bilateral base of the zonary leaf. Finally, the plaits close and form sheaths.

结果发现：中国石蒜的叶片在3月底开始分化，9月分化结束，11月，幼叶生长停止，并於翌年2、3月露出地面，5月即枯萎，完成生活史；叶片的形成经历4个阶段，即叶原座形成时期、叶原基生长时期、带状叶片的形成以及叶鞘的形成时期；叶原基先形成带状叶片，随后在其基部两侧形成褶，进而闭合发育成叶鞘。
