Construction of database on characteristics of genetic resources of orange subfamily plants.

佐贺大学保存了橙子亚科植物22属47种的遗传资源。这些植物材料已被评估为进一步用于品种和砧木改良。在本项目中，记录和评价遗传资源的特征信息来构建数据库，该数据库可以与其他遗传资源数据库相连接；花、果实、叶片和气孔的形态信息被记录和积累作为数据库。记录了10个柑橘属菌株和7个桑寄生属植物的解剖特征、挥发油成分和同工酶分析，以供系统发育研究之用。砧木矮化与树皮与木质部的比例有关。嫁接品种的矮化程度不能通过对砧木的解剖学研究来估计，高效液相色谱分析叶片中的黄酮类化合物和果汁中的有机酸对柑橘亚科植物的化学分类是有用的。

Genetic resources of 47 species in 22 genera of orange subfamily plants are maintained at Saga University. These plant materials have been evaluated for further uses of the cultivar and rootstock improvement. In the present project, the information on the characteristics of genetic resources are recorded and evaluated to construct the database, which can be linked with other databases on genetic resources.Information on the morphology of flower, fruit, leaf and stomata are recorded and accumulated as a database. The information on anatomical characteristics, components of essential oils and isozyme analysis of 10 strains of Citrus depressa and 7 strains of Poncirus trifoliate are recorded for the phylogenetic study. The dwarfism of rootstock is related to the ratio of bark and xylem. The dwarfism of scion cultivars cannot be estimated by the anatomical research on rootstocks.The analysis of flavonoid compounds in the leaf and organic acids in fruit juice by high pressure liquid chromatography are useful for the chemotaxonomy of orange subfamily plants.
