%X The allelochemicals and allelopathic potentials of rice (Huahang No.1) were investigated under different water,fertility,and light conditions with pot culture. The results showed that the allelopathic potential of Huahang No.1 was stronger at high levels of water and fertility,but its specific allelochemicals contents had no significant variation at both levels. The numbers of the total secondary metabolites and the contents of some anti pathogenic chemicals were increased at low level of water or fertility. Furthermore,the contents of specific allelochemicals in Huahang No.1 were lower under strong light than under weak light condition. Similarity,the allelopathic potential decreased,and the contents of some anti pathogenic chemicals maintained unchanged under weak light condition. No matter what levels of water,fertility or light conditions were,the allelopathic potential of Huahang No. 1 on associated weeds was weaker than that on non associated ones.
