Abstract
Seasonal changes in plant biomass, both aboveground and underground, and annual net production of a naturalized herbaceous perennial, Solidago altissima, were studied in 1964 at Toride, Ibaraki Prefecture. Seasonal peak of LAI of S. altissima community was 4.8 (late in August) and that of aboveground standing crop was 1230g d, w./m2 (late in October). Total loss by shedding of aboveground parts (mainly leaves) amounted to about 280g/m2 for the growing season from April through October. Annual net underground production was estimated to be about 290g/m2, which was about 24% of the maximum aboveground standing crop and about 20% of the annual net aboveground production. Annual net production of the whole community was 1780g/m2 or 17.8ton/ha. Three characteristic growth periods were distinguished according to the difference in growth pattern and productivity; i. e. the first period (April) was characterized by active growth of leaves and depletion of reserve substances in rhizomes, the second period (May-August) by high produttivity and active growth of stems, and the final period, especially in October, by rapid growth of daughter rhizomes. The highest rate of monthly net productivity was 380g/m2 in July and the lowest 80g/m2 in April.
