RESEARCH ON THE BIOMASS OF PAULOWNIA

  • Received Date: 1990-02-10
  • The biomass relations among different organs and the patterns of biomass change were studied in the biomass investigation with 1~8 year-old Pauloivnia elongata. Close relationship was found between the biomass of various organs and D1.32H. From the base to the top in a trunk, the biomass decreased successively. During the juvenile period, small twigs constituted the majority in the branch biomass. After 6~7 year-old, the branch biomass was contributed mostly to the large branches. Within the root biomass, 40%~60% came from the root-stake. The distribution of biomass among different types of roots varied with the tree's age. With the age increasing, the contribution of the large roots to the root biomass increased progressively and that of the small roots (the diameter4cm) decreased. According to their biomass, the organs rank was rootstrunkleavebranches before 3-year-old and trunkbranchrootsleaveflowersfruits after 3-year-old respectively.

Abstract: The biomass relations among different organs and the patterns of biomass change were studied in the biomass investigation with 1~8 year-old Pauloivnia elongata. Close relationship was found between the biomass of various organs and D1.32H. From the base to the top in a trunk, the biomass decreased successively. During the juvenile period, small twigs constituted the majority in the branch biomass. After 6~7 year-old, the branch biomass was contributed mostly to the large branches. Within the root biomass, 40%~60% came from the root-stake. The distribution of biomass among different types of roots varied with the tree's age. With the age increasing, the contribution of the large roots to the root biomass increased progressively and that of the small roots (the diameter4cm) decreased. According to their biomass, the organs rank was rootstrunkleavebranches before 3-year-old and trunkbranchrootsleaveflowersfruits after 3-year-old respectively.
