Other claims from this paper (13)
- Observation Heights and diameters of Korean pine seedlings showed a reverse J-shaped distribution.
- Intervention effect Total biomass of Korean pine seedlings was 3,627 kg/ha in the harvested stand versus 1,432 in the control stand.
- Observation The amounts of foliage were higher in both stands than in other artificially planted Korean pine seedlings.
- Intervention effect The ratio of foliage biomass to total biomass was 32% in the harvested stand and 42% in the control stand.
- Observation There were no significant differences in N and P concentration between the two stands among the different seedling parts.
- Intervention effect Total N content of seedlings was 22.50 kg/ha in the harvested stand versus 12.04 in the control stand.
- Intervention effect Total P content of seedlings was 2.48 kg/ha in the harvested stand versus 1.26 in the control stand.
- Intervention effect The ratio of foliar N content to total N content was 58.9% in the harvested stand and 65.3% in the control stand.
- Intervention effect The ratio of foliar P content to total P content was 53.0% in the harvested stand and 55.1% in the control stand.
- Intervention effect LMA was higher in the harvested stand than in the control stand.
- Observation The LMA of current-year foliage was lower than that of older foliage in both stands.
- Observation Total chlorophyll and chlorophyll b contents were higher in the control stand.
- Mechanism Seedlings showed increased LMA, decreased chlorophyll contents and increased biomass, resulting from improved light conditions following overstory harvesting.
