Abstract:
Annul growth rhythm of height, caliper and distribution of aboveground biomass on one-year seedlings of Pteroceltis tatarinowii were studied in this paper. The results indicated that growth pat- terns of height and caliper are fitted for S curve and can be simulated with Logistic equation. At the same time, the growing period of both height and caliper is divided into 4 stages according to its growth rate: emergence phase of seedling( before May 1), initiation phase of seedling growth(from May 1 to June 15 ), prosperous phase of seedling growth(from June 16 to August 15 ) and later phase of seedling growth( from August 16 to December 30). The production of prosperity period is 60% of gross of whole year. The paper also indicated that the biomass distribution ratio of leaf : xylem : bark was 40. 1 : 47.8 : 12. 1 and height and caliper are linear correlation with aboveground biomass and bark yields, however, two of correlation value of caliper with biomass and bark are higher than height’s.
