| Abstract: |
| To understand the status of oil plant resources in Mayanghe National Nature Reserve, Guizhou province, and to provide a scientific basis for protection and sustainable utilization of local oil plants, the oil plant resources in Mayanghe National Nature Reserve was analyzed and studied through field investigation and interview, combined with literature and specimen collection. The results showed that there were 78 families and 150 genera and 213 species of oil plants in Mayanghe National Nature Reserve, including 9 species of gymnosperms, 204 species of angiosperms. There were two dominant families,which had ten or more oil plant species,included Rosaceae and Lauraceae.Based on the diversity of life forms, arboreal oil plants (88 species) were dominated, accounting for 41.31% of total species. Seed，fruit and kernel were the main oily parts of the oil plants in Mayanghe Nature Reserve. The family and genus of the geographical distribution were mainly tropical. Mayanghe Nature Reserve is rich in species of oil plants, with various types of growth types, oily parts, and functions, but there are few kinds of developed commodities. Therefore, the protection of oil plant resources in Mayanghe Nature Reserve should be strengthened, as well as the development and utilization of the oil plant resources scientifically and rationally should be performed. |
