Abstract: The allelopathic effect of Eucalyptus urophylla Eucalyptus grandis forest soil on the content of chlorophyll,proline,and soluble sugar was tested by treating growth medium of four crops:Brassica parachinensis(false pakchoi),Brassica pekinensis(Peking cabbage),Oryza sativa(rice),and Raphanus sativus(radish)with aqueous extracts of the soil. Results showed highly significant differences(P<0.01)on content of chlorophyll,proline,and soluble sugar for the four crop plants. With an increase in aqueous extract concentration,chlorophyll content in receptor plant leaves decreased. Also,proline content rose first and then decreased as did soluble sugar of rice. Soluble sugar content from the four crop plants also declined. Thus, allelochemical resistance of rice was stronger than the other crops,and it was certain that there were some allelochemicals in the soil that caused different effects on the four species.[Ch,3 tab. 23 ref.]
