  • Title: [Habitat survey and biological characteristics study of Polygonum multiflorum germplasms in Guizhou region].
    Author: Liu HC, Luo CL, Li JL, Wang HL, Zhao Z.
    Journal: Zhong Yao Cai; 2013 Jun; 36(6):864-70. PubMed ID: 24380264.
    Abstract:
    OBJECTIVE: To provide reference in selecting premium provenance and improve the cultivation techniques of Polygonum multiflorum. METHODS: Field survey, routine field-observation and sampling fixed plant for analysis in lab were adopted. RESULTS: The growing adaptability of Polygonum multiflorum was very strong, which growed flourishly in the condition with adequate light, ample rainfall, rich heat and fertile soil; Along with the lower of latitude, the vegetative period was prolonged and reproductive stage was delayed, which prolonged the time of roots' nutrition acquisition. Time for root shoot ratio increasing continuously of low latitude germplasms was higher than that of higher latitude germplasms. CONCLUSION: Polygonum multiflorum germplasms have different biological characteristics because of different regions and habitats, which can provide useful reference for selecting premium provenance and adjusting measures to local conditions in different areas.
