Other claims from this paper (12)
- Observation Juvenile plants grown under 250 µmol/ms PAR at the initial stage maintained a relative growth rate of 80 mg/g · dry weight day.
- Observation At the initial stage of growth under 250 µmol/ms PAR, the main phytomass contributed to the leaves.
- Observation At the initial stage of growth under 250 µmol/ms PAR, the rate of net photosynthesis was high.
- Intervention effect Under decreased illumination of 20 µmol/ms PAR, juvenile plants lengthened their petioles.
- Intervention effect Under decreased illumination of 20 µmol/ms PAR, juvenile plants decreased leaf density.
- Intervention effect Under decreased illumination of 20 µmol/ms PAR, juvenile plants increased the size of the light-harvesting complex of leaf pigments.
- Intervention effect Limitation of light resources decreased the relative growth rate to 14 mg/g dry weight day.
- Intervention effect Restoring illumination to 250 µmol/ms PAR increased storage of plastic substances in the underground organs of juvenile plants.
- Observation Structural and functional changes indicate high efficiency of light resource use in spring and autumn.
- Intervention effect Summer shading caused a significant decrease in metabolic activity of juvenile plants.
- Mechanism The adaptive light strategy promotes effective growth during a long growing season.
- Mechanism The adaptive light strategy preserves the number of juvenile plants under intraspecific competition.
