Abstract:Under CO2 doubling, the content of chlorophyll and carotenoid per unit fresh weight and er unit area of leaves from weeping willow ( Salix babylonica L. ) as well as chlorophyll of eucommia ( Eucommia ulmoides Oliv. ) were raised, but carotenoid content of eucommia was reduced. The capability of light energy absorption of chloroplasts and regulative capability of excitation energy distribution between PS Ⅱ and PS Ⅰ were also raised by doubled CO2 condition.
