| 摘 要： | 以不同苗龄伊贝母幼苗为试验材料,采用连续收集法收集伊贝母不同苗龄根系分泌物,并采用气相色谱质谱联用技术(GC-MS)分析了根系分泌物的组分和含量.结果表明:一、二、三、四年苗龄伊贝母幼苗根系分泌物化合物在含量上存在较大差异,醛酮类化合物含量最多,分别为57.90%、74.15%、59.66%、59.32%.脲类、苯酚类、醇类含量较小,均在0.5%以下.但不同苗龄根系分泌物在种类和组成上相似,连续捕获系统获得的根系分泌物种类丰富,主要为有机物,包括烷烃类、酯类、醚类、烯烃类、苯酚类等有机物质. |

| Abstract: | The root exudates of Fritillaria pallidiflora Schvek seedlings with different ages were collected by using the continous cyclic device.The components and contents of the exudates were identified to examine the differences of root exudates at different ages by gas chromatography-mass spectrometry.The results showed that the ketone and aldehyde have the largest contents,which were 57.90%,74.15% and 59.66%,59.32% for one,two,three and four years old Fritillaria pallidiflora Schvek seedlings,respectively,while ... |
