To
evaluate the role of root respiration (Rr), we
measured spatial and temporal variation of Rr. We measured
root biomass, Rr and soil respiration (Rs) in temperature deciduous forest in central Japan.
The size dependence of Rr was shown
and Rr in fine root (< 2 mm) accounted
more than half of total Rr per unit
area. Moreover, we had measured continuously Rr
and Rs using automated system. Rr responded exponentially to soil temperature. High soil
moisture during and just after rainfall caused limiting factor in Rr. And the contribution of Rr
to Rs changed seasonally.
