Bamboo properties and applications

The objective of this study was to determine the effect of clump density on the production and distribution of biomass in commercial Bambusa vulgaris plantations cultivated under an annual rotation system in Northeast Brazil.The data were obtained one year after the last cut in populations led by regrowth and submitted to previous cuts for a 22-year period.Plantations I and II were located on slightly undulating terrain with 3.75 and 5.63 m 2 of average usable area per clump, respectively.Plantation III was characterized by its location on hilly terrain with 3.57 m 2 of area per clump.Three plots of 15 × 15 m were established in each plantation, from which three clumps were selected.The clumps were cut to estimate the dry biomass of leaves, branches, new culms, mature culms and rhizomes.The higher density of plants did not reduce the commercial biomass production per plant, while increasing the commercial production per hectare.Given the precocity of the cutting age considered, the relative proportion of culm biomass was new culms > mature culms > leaves > branches, showing a high biomass of new culms and leaves.The exploited biomass was only 38% of the total.
