Other claims from this paper (18)
- Observation The Sasa kurilensis community kept a nearly constant standing crop of 11 kg dry weight per m2 throughout the year.
- Observation The 2-year-old leaves were defoliated so that whole-leaf amount stayed at about 0.85 kg wet weight per m2, a leaf area index of about 5.
- Mechanism Productive structure recovers rapidly after thawing from winter dormancy, through strong elasticity of culms.
- Observation Relative light intensities under the Sasa community ranged from 1 to 7 percent, with a mean of 2-3 percent.
- Mechanism Such low light intensities may prevent the invasion of other plant species.
- Observation Dry weight of culms stayed at nearly 7.5 kg per m2 throughout the year.
- Observation Subterranean parts reached their maximum dry weight, 4.2 kg per m2, in early November.
- Observation Newly formed culms during the growing season weighed 390 g dry weight per m2.
- Observation Newly formed branches during the growing season weighed 245 g dry weight per m2.
- Observation Newly formed rhizomes during the growing season weighed 230 g dry weight per m2.
- Association Dry weight of culms was linearly related to the logarithm of culm diameter.
- Observation Dry weight of culms and rhizomes decreased in late spring to early summer, probably through use of reserved starch.
- Observation Dry weight of culms and rhizomes increased from early summer until late autumn.
- Observation The transformation factor from reserved substances into active organs was about 0.5.
- Observation The Sasa kurilensis community kept its daily net production at a fairly high level throughout the growing season.
- Observation Maximum daily increment of newly formed biomass was about 11 g per m2 per day.
- Observation Annual net production of the Sasa kurilensis community was estimated at 1.6 kg per m2 per year.
- Observation The S. nikkoensis community achieved almost the same net production as the S. kurilensis community despite a smaller standing crop.
