摘    要:以强化感水稻品种PI312777和弱化感水稻品种Lemont为供试材料,运用“循环法”收集供试水稻经土壤和石英沙介质后的根系分泌物,并经乙醚萃取,所获萃取物经气相色谱 质谱联用仪(GC-MS)测试,检索谱图库确定化合物.结果表明,乙醚萃取物中检测到含氧萜类化合物,如柠檬烯氧化物、柠檬烯二氧化物、香芹酮氧化物、香芹醇、雪松醇等,不同品种间含氧萜类化合物种类相似,但在不同介质中的存留方式和数量存在差异.文中还就不同培养方式和品种间萜类化合物的差异作了进一步讨论.

关 键 词:水稻  化感作用  萜类化合物  化感物质

Abstract:In this paper,a strong allelopathic rice variety PI312777 and a weak allelopathic rice variety Lemont were used as test materials,and the root exudates of two rice varieties grown in the media of sand and soil were respectively collected by using circulation system approach.The terpenoids in ether-extracts were detected by GC-MS,and characterized by spectrum database.The results showed that some terpenoids such as limonene oxide,limonene dioxide,carvone oxide,carveol,and cedrol were detected in the ether-extracts.Different rice varieties had the similar kinds of terpenoids,but their existing modes and quantities were different.The differences between different various cultural methods and between rice varieties were further discussed.
Keywords:Oryza sativa  Allelopathy  Terpenoids  Allelochemicals
