e1“Productive structure and its seasonal variation were studied also in S. nipponica- and S. nikkoensis-communities. The latter could achieve almost the same amount of net production as that of the S. kurilensis community, in spite of the smaller standing crop”

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 Subterranean parts reached their minimum dry weight, 3.0 kg per m2, in mid-August.
- 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.
