Abstract

We researched the decomposition of leaves of Syzygium jambos and Michelia alba allocated into coarse and fine mesh bags in terrestrial habitat(210 d) and pond(60 d) at the Changgangshan Nature Reserve,Guangzhou.The breakdown rates of S.jambos in coarse and fine mesh bags were 0.003 318d^-1 and 0.003728d^-1,while those of M.alba litter were 0.009238d^-1 and 0.004379d^-1,respectively,in terrestrial environment.In lentic environment,the breakdown rates of S.jambos in coarse and fine mesh bags were 0.009 536d^-1 and 0.012 591d^-1,while those of M.alba litter were 0.017 949d^-1 and 0.020 759d^-1, respectively,indicating that the leaf litter decomposition rates of the two species were lower in terrestrial habitat than in lentic environment.Furthermore,the decomposition rates of S.jambos were lower than those of M.alba both in terrestrial habitat and in lentic environment,mainly due to its high content of polyphenols which can inhibit the growth of microbes.
