Abstract: A field experiment was conducted to research biomass allocation and estimation models of Rauvolfia vomitoria and Rauvolfia verticillata , in Xishuangbanna, Yunnan Province . Biomass measurement was conducted with harvest method, and estimation models were set up by following equations: linear , logarithmic, binomial, and power models . The results
showed that the biomass between these two species is obvious, R. vomitoria is higher than R. verticillata , and stems have the highest proportion to the whole plant , roots come next, and leaves lowest . The estimation coefficients (R2 ) were high and the models had certain applicability.

Key words: A field experiment was conducted to research biomass allocation and estimation models of Rauvolfia vomitoria and Rauvolfia verticillata
