Allelopathy Effects of Various Higher Landscape Plants on <i>Chlorella pyrenoidosa</i>

In this paper, the effects of the culture water of three types of higher landscape plants Typha latifolia L, Canna indica L and Iris tectorum Maxim on the growth of Chlorella pyrenoidosa have been investigated. The results show that Iris culture water promoted the growth of Chlorella pyrenoidosa, which was facilitated at low contentions and inhibited at high concentrations by the culture water of Canna indica L. Moreover, inhibitory effect of the culture water of Typha latifolia L was the strongest with the rate of 50.7%. Differences of the effects of the three plants on the chlorophyll a contents of Chlorella pyrenoidosa were significant (P Iris tectorum Maxim was utilized, whereas the content was lowest at merely 41% of that of the control group when treated with 80% of the culture water of Typha latifolia L.
