Abstract
The decomposition dynamics of various types of Mesua Jerrea litter were studied in a tropical rain forest zone of the Indian eastern Himalaya Arunachal Pradesh. The senesced leaves. twigs 2 mm) and fruit coat decomposed in a three-phased pattern while the green leaves showed a two-phased decay pattern. All phases were characterised by a composite linear regression model Y a bX eX dX ... where Yis the percentage of initial mass remaining a the Y intercept b the rate of change in Y with respect to time e the shift parameter for adjustment of the Yintercept in phase II and d the shift parameter for adjustment of the Y intercept in phase III. The values of e and d were taken as zero if decay was slow and/or equal to one if decay was rapid. The annual decay constant was maximum (0.8) for senesced leaves and minimum (0.4) for twigs. Initial litter chemistry influenced the rate of decomposition of M. Jerrea litter.
