拟侵填体是筛管或裸子植物分泌道中发现的类似导管侵填体的结构，裸子植物分泌道中的拟侵填体由树脂道上皮细胞发育而来，而在被子植物分泌道中的拟侵填体尚缺乏系统研究；本研究拟在前期对漆树乳汁道拟侵填体研究的基础上，采用植物解剖学、组织化学及其细胞化学等方法，以我国产漆树科四种代表植物为材料，系统研究该科植物分泌道中拟侵填体的存在状况、结构特征以及发生、发育规律，并进行拟侵填体超微结构和细胞化学的研究，从细胞水平探讨漆树科植物拟侵填体结构与次生代谢产物之间的关系，分析其种间差异，为被子植物分泌道拟侵填体的研究提供理论依据。

Tylosoids are outgrowths of parenchyma cells into sieve elements and epithelial cells into intercellular resin ducts in many pinus species, however, tylosoid in the angiosperms secretion lumina was lack of systematic research. On the basis of preliminary studies of tylosoids in T. vernicifluum laticiferous canals, 4 kinds of Anacardiaceae plants which distribute in China were choose as materials, combine with anatomical, histochemical and cytochemical methods to study the structural and development characters of tylosoids systematic, ultrastructure and cytochemistry studies of tylosoids will investigate synchronously. Explore the relationship between the structure and secondary metabolites on the cellular level. Analysis the correlation between different species, provide a theoretical basis for the tylosoids research in angiosperms secretion lumina.
