| 内容記述 | Characteristics of rhizome resource storage of common reed, Phragmites australis (Cav.) Trin. Ex Steudel, were investigated associated with the aboveground biomass in terms of rhizome age category. Age-specific rhizome biomass and total nonstructual carbohydrate (TNC), and standing stock of aboveground biomass were observed monthlu. The biomass of one- or two-year old rhizomes did not reduce during the growing season, while a large reduction was observed with older rhizomes. TNC concentration declines twice a year, first in May before the recovery in late spring and second after August, followed by recovery in November. The amount of remobilized TNC is negatively correlated to rhizome age during spring growth and autumnal translocation, except for one year old rhizomes. Analyses of carbon budgets implies that the spring decline is caused by the remobilization of TNC for the aboveground biomass growth and rhizome respiration, and that of autumn is mainly due to respiration, while translocation of dead shoots contributes to the subsequent recovery of rhizome biomass. The nitrogen contents substantially decrease decrease during the second summer, however, phosphorous contents reduce gradually during the whole year. | |||||||||||||
