- Observation Light intensity significantly affected germination rate, survival rate, establishment rate and germination index.
- Observation Germination rate was maximal at 40% light intensity.
- Observation Survival and establishment rates were maximal at 100% light intensity.
- Observation Stem length increased as light intensity declined.
- Observation Euphylla number declined as light intensity declined.
- Observation Basal stem diameter did not differ significantly among light intensities.
- Observation Total, root and stem biomass were highest under 100% light intensity.
- Observation Leaf biomass was highest under 100% light intensity.
- Observation Photosynthesis non-photosynthesis biomass ratio and leaf biomass ratio declined with falling light intensity.
- Observation Stem biomass ratio increased with falling light intensity.
- Observation Root to shoot ratio and root biomass ratio did not differ significantly among light intensities.
- Observation Low light promoted seed germination.
- Observation Seedlings grew slowly under low light.
- Observation Seedling mortality was high under low light.
- Mechanism The authors attributed greater low-light tolerance to greater stem biomass accumulation.
