摘要： 利用固相微萃取法（SPME）和气质联用（GCMS）技术对常规稻（化感稻3号、象牙香占）和杂交稻（软华优3号、农珍优3号）的4个不同生育期叶片挥发物成分及其相对含量进行了比较分析。结果表明，杂交稻叶片挥发物成分比常规水稻多。化感稻3号共检测出41种物质，象牙香占共检测到37种物质。软华优3号共检测出49种物质，农珍优3号共检测出53种物质。化感稻3号、象牙香占和软华优3号均是乳熟期挥发物成分最多，农珍优3号则是完熟期最多。在同一生育期常规稻和杂交稻叶片挥发物成分及相对含量虽然有一定差异，但规律不明显。随水稻的成熟叶片烷烃类和萜烯类的相对含量总体呈下降趋势。4种水稻各生育期共有的化合物为长叶烯和角鲨烯。软华优3号在扬花期检测出(Z)3己烯醇，象牙香占和农珍优3号在完熟期检测出γ己内酯两种绿叶挥发物。这些化合物与水稻品质、有害生物之间的关系值得进一步深入研究。

Abstract: Volatile components of conventional and hybrid rice leaves were analysed by solid phase microextraction (SPME) and gas chromatographymass spectrometry(GCMS) with two conventional rice varieties(Allelopathic rice 3, Xiangyaxiangzhan) and two hybrid  rice combinations (Ruanhuayou 3, Nongzhenyou 3) as materials during four developmental stages. The results showed that 41 and 37 components were identified in Allelopathic rice 3 and Xiangyaxiangzhan; 49 and 53 in Ruanhuayou 3 and Nongzhenyou 3. For Allelopathic rice 3, Xiangyaxiangzhan and Ruanhuayou 3, the number of volatile components maximized during milkripe stage, while for Nongzhenyou 3 during fullripe stage. There were some insignificant differences in volatile components and their relative content between conventional rice and hybrid rice combination during the same stage.  The relative content of alkanes and terpenes decreased with rice ripening in the four tested rice. Longifolene and Squalene were identified in all tested rice during different stages. (Z)3Hexenol from Ruanhuayou 3 in flowering stage and γCaprolactone from Xiangyaxiangzhan and Nongzhenyou 3 in fullripe stage were identified, these two components were green leaf volatiles.The relationship between these components and rice quality, pests was worth of further study.
