英文摘要	The effects of different phosphorus (p) concentrations (0.36, 3.6, and 36 mu mol/l corresponding to low-, middle-, and high-p concentration groups, respectively) and nitrogen (n)/p ratios on the growth and photosynthetic characteristics of skeletonema costatum and prorocentrum donghaiense were studied. for both species, the high-p (hp) concentration group showed the greatest algal density and highest specific growth rate. changes in the maximum efficiency of photosystem ii (f (v) /f (m) ) were monitored under the various p and n/p conditions. the largest decrease in f (v) /f (m) was in the low-p (lp) group in s. costatum and in the hp group in p. donghaiense. there were high rapid light curves and photochemical quantum yields (i broken vertical bar (psii)) for s. costatum in the hp group, while the actual photosynthetic capacity was higher in p. donghaiense than in s. costatum in the mp group. under eutrophic but relatively p-restricted conditions, p. donghaiense had higher photosynthetic activity and potential, which could cause this dinoflagellate to increasingly dominate the phytoplankton community in these conditions. under the same p concentration and n/p ratio, p. donghaiense had a larger relative maximum rate of electron transport and higher i broken vertical bar (ps ii) values than those of s. costatum. these differences between p. donghaiense and s. costatum may explain the interaction and succession patterns of these two species in the changjiang (yangtze) river estuary from a photosynthesis perspective.
