ABSTRACT

Aegiceras corniculatum grows as single-stemmed evergreen shrub or small tree in the Sundarbans mangrove forest of Bangladesh. The objectives of this study were to derive the allometric models for estimating above-ground biomass, nutrients (N, P and K) and carbon stock in A. corniclatum. A total of 8 linear models (y = aX + b,

, y = aLogX + b, Logy = aX + b, Logy = aLogX + b, y = alnX + b, Lny = aX + b and Lny = alnX + b) with 64 regression equations were tested to derive the allometric model for biomass of each plant part; and nutrients and carbon stock in total aboveground biomass. The best fit allometric models were selected by considering the values of R², CV, R_mse, MS_error, S_a, S_b, F value, AICc and Furnival Index. The selected allometric models were Logbiomass = 0.76LogDBH² - 1.39; Biomass = 0.07DBH² - 0.49; Logbiomass = 1.04LogDBH² - 1.80; Logbiomass = 1.04LogDBH² - 0.99;

= 0.48DBH - 0.13 for leaves, branches, bark, stem without bark and total above-ground biomass respectively. The selected allometric models for Nitrogen, Phosphorous, Potassium and Carbon stock in total above-ground biomass were

= 0.67DBH + 0.11;

= 0.94DBH + 0.08;

= 1.06DBH - 0.18;

= 0.33DBH - 0.09 respectively.
