Successive degradation of the light-harvesting system of the photosynthetic apparatus during senescence of barley flag leaves

摘要

Levels of light-harvesting complexes were investigated during maturation and senescence of flag leaves derived from field-grown barley plants (Hordeum vulgare L.). In mature flag leaves possessing photosynthetically highly active chloroplasts levels of the major light-harvesting complex LHCII and also of the minor light-harvesting complexes CP29 of photosystem II and LHCI of photosystem I were high.
