Other claims from this paper (10)
- Intervention effect Quercus serrata seedling emergence was significantly lower at 5% soil moisture than under other treatments and than Quercus variabilis.
- Intervention effect The emergence period was shortest at 20% soil moisture for both oak species.
- Observation Seedling survival did not differ among treatments or between oak species.
- Association Organ dry weight tended to increase with relative light intensity in both species.
- Association Organ dry weight tended to increase with soil moisture in both species.
- Intervention effect Reducing soil moisture from 20% to 10% caused a small proportional dry-weight decrease in Quercus serrata.
- Intervention effect Reducing soil moisture from 20% to 10% caused a large proportional dry-weight decrease in Quercus variabilis.
- Association The top-to-root ratio and leaf dry-weight share remained approximately constant as light declined in Quercus serrata.
- Association The top-to-root ratio and leaf dry-weight share tended to rise as light fell from 10% to 3% in Quercus variabilis.
- Association The top-to-root ratio and leaf dry-weight share tended to decline as soil moisture fell in both species.
