To study the effects of allelochemicals of Arundo donax Linn. on the growth of @entity16589 , the allelochemicals were extracted with three solvents ( @entity1042 , @entity1046 and @entity4315 ), respectively. Based on the observation of algal morphology and the measurement of algal density and cell size, the results showed the allelochemicals extracted with all the three solvents had inhibition on @entity16589 . The appearance time of allelochemical inhibition increased as follows, allelochemicals extracted with @entity1042 < @entity1046 < @entity4315 . As treatment time extended, @entity16589 regrew at low doses of allelochemicals extracted with @entity1042 . Their inhibitory effects at high doses were lower than those extracted with @entity1046 and @entity4315 . After 2 d and 4 d of treatment, the inhibition ratios of allelochemicals extracted with @entity1046 and @entity4315 reached almost 100%, respectively. The 50% effective concentrations (EC50, 6 d) of allelochemicals extracted with @entity1042 , @entity1046 and @entity4315 were 0.17 g x L(-1), 0.05 g x L(-1) and 0.08 g x L(-1), respectively. The allelochemicals extracted with @entity1042 caused cavities in cells, those with @entity1046 caused cells into cavities, pieces and conglomeration, and those with @entity4315 caused goffers on cells initially with conglomeration later. The allelochemicals extracted with all the three solvents decreased the cell size of @entity16589 , among which those extracted with @entity1046 had the strongest action.
