The Allelopathic Potential of Root Exudates from Ageratina adenophora Spreng on Different Conditions

Abstract

Abstract: This paper studied the allelopathy of root exudates from Ageratina adenophora Spreng seedings which grew on different conditions by bioassay. With the comparison of no treated immature Ageratina adenophora, root exudates from Ageratina adenophora on different conditions were collected by cyclic irrigation. Component content of root exudates were determined by Gas chromatography/mass spectrometry (GC/MS) to examine the difference of root exudates of Ageratina adenophora seedlings on different conditions. When the allelopathic potential of root exudates from Ageratina adenophora on the growth of upland rice were examined under indoor natural conditions and 1000 mg/kg, it indicated that the allelopathic inhibiting effect of root exudates from Ageratina adenophora were not significant. However, while the plants were treated with herbicide stress and aphid feeding, the allelopathy would be enhanced significantly. It showed after it was treated with physical damaged, herbicide stress and aphid feeding, the root exudates of Ageratina adenophora seedlings contained similar chemical compounds in which were mainly esters and ketones, and the content of primary components of root exudates from Ageratina adenophora was different by GC/MS, as well as the content of main components of root exudates maybe change the allelopathy of root exudates.
