Decomposition of Different Components of Muli Bamboo in Sub-tropical Forests of Mizoram, Northeast India: Effect of Climate

Abstract


In the present study decomposition of leaf, branch, culm and sheath litter of the bamboo Melocanna baccifera in relation to monthly average precipitation (MAP) and monthly average temperature (MAT) was carried out. It was observed that the remaining mass at 180 days was 11% in leaf, 62% in sheath, 72% in branch and 78% in culm litter. Significant positive correlation of k (month-1) was recorded with MAT in leaf litter; with MAP in branch litter; with MAP and MAT in culm litter, however an inverse correlation with MAP in sheath litter was recorded. The negative response of sheath litter to MAP can be attributed to resistance during decomposition in the initial stage which corresponds to more rainy months.


Keywords
