Major Research Achievements

In recent five years, the photosynthesis of more than 20 species belonging to Cypripedium, Paphiopedilum, Dendrobium, Incarvillea, and Camellia were investigated. These studies provide our insight for photosynthetic adaptation of wild plants to light, temperature and water availability.
The leaf traits, such as leaf anatomy, photosynthesis, leaf life span, and leaf element content were especially compared between Cypripedium and Paphiopedium, both belong to Cypripediodeae. The results suggest that the differences in leaf traits between Cypripedium and Paphiopedilum reflect their adaptation to contrasting habitats and are shaped by both phylogeny and environment.
The relationship between mycorrhizal fungi and orchids including Cypripedium, Paphiopedilum and Dendrobium were studied. The phylogenetic analysis revealed for the first time that mycorrhizal fungi in Paphiopedilum were members of the fungal family Tulasnellaceae, just the same as that in Cypripedium, having strong specificity. Different species of Cypripedium or Paphiopedium with similar habitats might have some identical mycorrhizal fungi, but the dominant mycorrhizal fungi for each orchid species were not the same. The dominant fungi are determined by the species and habitats.
From 2006, More than 30 papers were published in the journals, and 7 patents and 7 new varieties have been registered. Our research achievements were contributed to Yunnan Green-land Biotechnological Co., Ltd., which was successfully listed in the stock market in 2007, KIB became to a shareholder of this enterprise, owning 6,712,474 stocks. Our group was awarded 5000,000 RMB by KIB due to outstanding contribution of scientific achievements industrialization.
