Phenolic Allelopathic Effects of Mongolian Oak Leaf Extract and Wood Vinegar
Using mongolian oak leaves and wood vinegar as raw materials,the components were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the components with higher relative content in mongolian oak leaf extract were 2,3-dimethyl-2-cyclopentene-1-one(13.49%),2-methyl phenol(9.22%),etc.The components with higher relative content in wood vinegar include guaiacol(28.27%),phenol(7.78%),p-cresol(4.97%),2,3-dimethyl-2-cyclopentene-1-one(4.93%),etc.The seed germination experiment showed that compared with the control group,leaf extract diluted 50,100,200,and 400 times significantly inhibited the germination rate of pakchoi,while diluted 50,100,200,400,800,and 1600 times significantly inhibited the germination rate of mustard;Diluting wood vinegar 50 times significantly inhibits the germination rate of mustard,while phenolic compounds in leaf extracts and wood vinegar have a certain inhibitory effect on seed germination rate.
