     View Summary

    Pyrus ussriensis Maxim. is native to the northern part of China, but whose habitats are currently being destroyed by environmental changes and human deforestation. Wild Ussurian pear populations possessed low genetic diversity as a result of habitat fragmentation. These were divided into 5 groups based on the Bayesian clustering method using nSSRs and by haplotype distributions by cpSSRs. The genetic diversity of the populations in Inner Mongolia and north east of Heilongjiang representing unique genotypes was especially low. These populations need urgent conservation because of their genetic vulnerability and peculiarity. Distant evolutionary relationships between P. ussuriensis Maxim. in China and var. aromatica in Japan inferred from phylogenetic analysis are also discussed. Although wild sand pears were also explored on mountain areas in central region of China, individuals sampled were identified with interspecific hybrids between sand pear cultivar and pea pear by DNA analysis.

  • Conservation of the endangered annual plant, Mitrasacme pygmaea R. Brown (Loganiaceae) : life history, ecology, germination traits and genetic diversity

     View Summary

    To conserve the natural populations of the endangered annual plant, Mitrasacme pygmaea R. Brown (Loganiaceae) grown at Botanical Garden,Osaka City University, we investigated its distribution, the life histories, the environmental conditions suitable for the growth, the breeding system and the genetic diversity. As a result, we found three more localities the plants were distributed in Osaka pref. And its seedlings appeared at the end of May and flowering began in August. The seeds of the plant revealed to be photoblastic and the enough light intensity were necessary for the germination and growth. They were self-compatible and produced seeds mainly through self-pollination. We could not detect the geographical genetic structures among eight populations examined. We concluded that the maintenance of enough light conditions and proper weeding time and frequencies corresponding to the growth stages would be the most effective for the conservation of this plant.

  • Program development for environmental education through the use of Botanical Gardens of Osaka City University with the participation of citizens.

     View Summary

    This project was performed at the Botanical Gardens of Osaka City University. Different forests at the almost same geographical conditions consisted of different wood species were revealed to show different carbon dioxide fixation. Insect fauna, spider fauna and avifauna were surveyed. Those results indicated that ecosystems with abundant species including endangered species were regenerated after 60 years since planting. Based on these results, environmental education programs were developed and done for citizens and children as Environmental course or Forest class.

  • Researches on the introgression between pre-historically naturalized plants and native plants in Pyrus

     View Summary

    Using microsatellite analyses we revealed that the extensive introgression between Pyrus ussuriensis, which is a threatened plant distributed in the Kitakami Mountains and P. pyrifolia, which is a prehistorically introduced plant. The introgressed plants are distributed widely in this Mountains, even in natural habitats, whereas the plants estimated as genetically true native grow very limitedly. However, we were able to infer the genotypes of true native plants, their original distribution area and habitats. They will become useful for their future conservation.
