ABSTRACT
Allometric relationships between biomass of different components of saplings and trees of Bruguiera parviflora and diameter at breast height (DBH) were established and biomass proportion at different components of saplings and trees were also estimated. Linear relationships were observed when the biomass of individual component of saplings and trees were plotted against diameter at breast height (DBH) on a log-log scale. All regression equations both for saplings and trees were highly significant (p<0.05) and the regression co-efficient values found to exist above 0.89 except the sapling roots. Significant (p<0.05) differences in regression slopes and co-efficients were observed for all the components of saplings and trees. The mean percentage of total above and below-ground biomass of saplings and trees were 84.29 and 88.79%; 15.71 and 11.21%, respectively.
ABSTRAK
Hubungan alometri di antara biojisim dan diameter pada paras dada (DBH) bagi komponen-komponen berbeza anak-anak pokok dan pokok dewasa Bruguiera parvifolia telah diwujudkan, dan nisbah biojisim bagi komponen berbeza anak-anak pokok dan pokok dewasa juga dianggarkan. Pertalian linear telah diperhatikan apabila biojisim bagi komponen individu anak pokok dan pokok dewasa diplotkan melawan DBH pada skala log-log. Semua persamaan regresi bagi anak pokok dan pokok dewasa adalah amat signifikan (p<0.05) dan nilai-nilai pekali regresi adalah melebihi 0.89, kecuali akar anak pokok. Perbezaan yang signifikan (p<0.05) bagi kecerunan-kecerunan negresi dan pekali-pekali dilihat pada semua komponen anak-anak pokok dan pokok dewasa. Min peraturan biojism atas tanah dan bawah tanah bagi anak-anak pokok dan pokok dewasa adalah masing-masing 84.29% dan 88.79%; 15.71 dan 11.21%.
