Authors:Nath, A.J; Das, A.K

Abstract:Leaf phenology and biomass increment of the culms of Bambllsa cacharensis, a priority village bamboo was studied in the Cachar district ofAssam, Northeast India. Leafphenological parameters were associated with the seasonal changes. Leaf area expansion and leaf dry weight increment was greatest during warm and wet rainy season, Specific leaf area (SLA) exhibited inverse relation with leaf area and leaf dry weight. Pattern of biomass allocation changed with the culm maturity and culm phenology, Leaf and branch biomass showed the highest accumulation rate during the peak leafappearance period while sheath, culm and total biomass showed the highest rate during the rapid phase of culm growth, Biomass acquisition is manifested by a shifting strategy of resource investment between culm and leaf component. Outcome of the study is discussed in the context to scientific management and efficient utilization of this bamboo species,
