| 英文简介 | Currently, the adaptive evolution of some key water transport traits of woody plants is one of the cutting-edge issues in the ecophysiological research of woody plants. Picea species (Picea: about 34 speices in the world) are the dominant forest tree species in China and even the Northern Hemisphere with significant phenotypic variation and clear phylogenetic history, which widely distributed in the cold temperate zone and the alpine regions of temperate zone. Herein, Picea species is the ideal materials to study the adaptive evolution of some key functional traits of plant water transport. This project will rely on the applicant has established spruce common garden (total of 34 kinds, more than 250 kinds of sources) in three different geographic regions, systematically analyse the relationships of environmental plasticity, genetic variation and phylogenetic history of some key water transport traits in Picea species, such as xylem anatomical features, hydraulic conductivity, and the ability of anti-embolism, explore the adaptive evolutionary mechanism of the key features of plant water transport, and effectively screen the suitable spruce species for growing in Chinese arid and alpine regions.So, these results will provide a certain scientific basis and practical support for the protection and utilization of the important spruce resources in the Northern Hemisphere, especially for Chinese cold and arid regions, as well as for the recovery of the spruce forest and the screening of suitable spruce spreces in the major national forestry ecological engineering. |
