Abstract


Dendrocalamus hamiltonii one of the promising species of clumping bamboos is known for its root system which spreads vertically and holds the soil strongly, effective measure to prevent soil erosion as well to accumulate large quantities of carbon in terms of biomass. Estimation of above ground biomass of this species was conducted through multiple regression at Agriculture Research Station, Majhera situated in Nainital District of Uttarakhand, India. Results highlighted accumulation of 35.61 kg biomass per clump contributed by culm, branches and leaves on fresh weight basis. Above ground biomass on per culm basis was at par with the reports available but total number of culms produced per clump was less. An increase of 293.87 per cent was observed on dry weight basis in two years interval after the plantation was well acclimatized. Correlation matrix of growth parameters of small micropropagated plants showed positive correlation between length and weight of twigs, weight of leaves and leaf area index. However, weight of leaf and leaf area index showed strongly positive correlation.
