| 摘 要： | 利用生物检测法研究海南和广东几个不同地区假臭草(Eupatorium catarium Veldkamp)的化感作用,研究结果表明,不同地区的假臭草水提液对受试种子的萌发和幼苗生长的化感作用差异明显；海南地区的假臭草化感作用强于广东地区的假臭草的化感作用;广东不同地区假臭草化感作用由强到弱顺序为鹤山,阳江,徐闻；海南不同地区假臭草化感作用由强到弱顺序为琼中,琼海,儋州,三亚,海口.推测各地区假臭草化感作用差异可能是假臭草生境不同所致.

| Abstract: | Use of biological test methods to determine the plant allelopathy differences of Eupatorium catarium Veldkamp from several different areas in Hainan and Guangdong regions,the results of the study showed that,the water extraction liquid of E.catarium from different regions showed significant differences in allelopathy in germination of seeds and seedling growth;and E.catarium in Hainan areas had stronger allelopathy than in Guangdong areas.In Guangdong,allelopathy of E.catarium from different areas could be ordered as Heshan>Yangjiang>Xuwen.In Hainan,allelopathy of E.catarium from different areas could be ordered as Qiongzhong>Qionghai>Danzhou>Sanya>Haikou.The different allelopathy of E.catarium with different areas maight be as the result of the different habitats. |
