Laboratory studies were conducted to determine the allelopathic activities of leaf powder of 38 plant species with method of grinded powder of plant mixed with agar(PPA) we developed. Growth of radicles and hypocotyls of lettuce as a test plant were inhibited due to the allelopathic *** inhibition effect was higher for radicles than for *** these plants,the inhibition rates of leaves of Nandina domestica,Pittosporum tobira,Hypericum chinensis, Hedera nepalensis,Koelreuteria bipinnata,Punica granatum,Petunia hybrida,Pinus armandii, Acer palmatum,Prunus persica,Albizia julibrissin and Hemerocallis fulva for radicle elongation reached above 90%.These results provide important evidence for further study allelopathy and developing bionic herbicides.
