摘要

The objectives of this research were to determine suppression rates on rice blast (Pyricularia oryzae Cavara), sheath blight (Rhizoctonia solani Kühn),anthracnose (Colletotrichum coccodes), Phytophthora capsici and Botrytis cinerea, and shoot and root lengths of plant species by using ethanolextracts from roots of four Polygonaceae species (Rheum palmatum, Polygonum cuspidatum, Rumex crispus and Polygonum multiflorum) and seedsof one Fabaceae species (Cassia obtusifolia L.),containing chrysophanol and emodin and to confirm whether contents in the five plant species arerelated to the suppression levels of above various pathogens and plants. Rice blast was completely suppressed by ethanol extract at 3% concentrationof Rheum palmatum roots. Other pathogens Phytophthora capsici, Botrytis cinerea, Rhizoctonia solani Kühn, and Colletotrichum coccodes weresuppressed 100%, 94%, 89%, and 59% by 3% concentration of the Rheum palmatum extract, respectively. Rice blast was suppressed 84% and 90%by chrysophanol and emodin treatments (249 g/ml), respectively. Suppression rates on rice blast showed 69% and 52% by extracts at 5%concentrations of Cassia obtusifolia and Polygonum multiflorum, respectively, but showed low suppression in Polygonum cuspidatum and Rumexcrispus extracts. In addition, Rheum palmatum and Polygonum multiflorum extracts showed higher suppression rates in sheath blight, anthracnose,and Phytophthora capsici. Shoot and root lengths in cucumber and barley also showed higher inhibition rates in Rheum palmatum and Polygonummultiflorum extracts than those of Rumex crispus, Polygonum cuspidatum and Cassia obtusifolia L. Higher suppression rates on pathogens and plantsin Rheum palmatum and Polygonum multiflorum were related to higher total contents of crysophanol and emodin.
