Research Abstract |
To better understanding of belowground carbon cycle in the forest ecosystems, 13C labeling method was applied to a Quercus serrata tree in the field 7 times in 2011. Respired 13CO2 from trunks, coarse and fine root was tracked using tunable diode laser absorption spectrometry to determine time lags and the velocity of carbon transfer. The seasonal dependencies were observed with shorter time-lags and higher velocity in the summer and longer time-lag and lower velocity in the autumn.
