Research Abstract

Seasonal patterns of fine-root production and nutrient uptake by oak (Quesruc crispula) and understory vegetation, Sasa (Sasa veitchii) were determined and compared by growing separately under the same environmental condition. The two plants revealed different seasonal patterns of root production and nitrogen uptake. This difference might have been caused by difference in leaf phenology among the plants. These results show that not only tree species but also understory vegetation should be taken into account for evaluating temporal pattern of nitrogen dynamics in forest ecosystems.
