Growth inhibition of Prorocentrum minimum by Ulva pertusa Kjellm under different N and P nutrient limitations

The effects of different N and P nutrient limitations on the growth inhibition of Prorocentrum minimum by Ulva pertusa Kjellm fresh tissue and dry powder were studied in this paper. The results showed that U. pertusa fresh tissue and dry powder could inhibit the growth of P. minimum, and the growth inhibition was more significant with the increased contents of U. pertusa fresh tissue and dry powder. The growth inhibition of P. minimum could be changed under different N and P nutrient limitations. The growth inhibition rates of P. minimum by U. pertusa fresh tissue were N and P sufficient > P limited > N limited > N and P both limited. The growth inhibition of P. minimum by U. pertusa dry powder was decreased but not significantly (p>0.05) when N and P were limited.
