SUMMARY The relative amounts of chlorophyll b (C b ) and chlorophyll a 685 (C a 685) are determined for seven plant species. It is found that the amount of the C b – C a 685 chlorophyll‐protein complex is correlated with the relative amounts of both C b , and C a 685. However, this relationship differs for these chlorophylls. The same relations are studied for a single species, Phaseolus vulgaris , grown under various light intensities. No changes are observed in plants grown at intensities ranging from 15 to 150 W · m 2 . At 8 W · m 2 the amount of the C b – C a 685 complex is hardly changed. However, the ratio of the relative amounts of both components is clearly increased. The results are discussed.
