Observation At spring light levels, most biomass was allocated to leaves.
Observation At spring light levels, net photosynthesis was high.
Intervention effect Reduced illumination lengthened petioles.
Intervention effect Reduced illumination lowered leaf density.
Intervention effect Reduced illumination enlarged the leaf pigment light-harvesting complex.
Intervention effect Light limitation reduced relative growth rate to 14 mg/(g dry mass day).
Intervention effect Restored light activated growth.
Intervention effect Restored light promoted storage of plastic substances in underground organs.
Mechanism Authors interpret seasonal structural and functional changes as efficient light use in spring and autumn and lower metabolic activity in summer shade.
