| 摘 要： | 本文对7个史密斯桉无性系桉叶的出油率进行了测定，对其精油成份进行了分析。结果表明：在7个史密斯桉无性系中，出油率在3．0％以上的有17号、2号、8号，出油率分别达到3．67％、3．61％、3．20％，出油率分别超过史密斯桉实生苗91．43％、88．62％、67．39％，分别超过蓝桉实生苗131．97％、128．18％、102．29％，具有较高的精油得率；精油成份分析表明：在7个史密斯桉无性系中1,8-枝叶素含量在80％以上的有4号、8号、7号、1号无性系，分别为82．85％、80.31％、80．26％、80．05％；以1,8-桉叶素产量为首选指标的综合分析表明，出油率是1,8-桉叶素产量的关键因素，出油率与1,8-桉叶素产量呈正相关。

| Abstract: | This study investigated the leaf oil yields for 7 clones of Eucalyptus smithii and analyzed components of the leaf essential oils from these clones. The results showed： 1） among the 7 clones, the oil yielding rate of clones 17 （3.67%）, 2 （3.61%） and 8 （3.20%） were over 3.0% and the leaf oil yields of these three clones were 91.43%, 88.62% and 67.39% higher respectively than the average for Eucalyptus smithii seedlings, and 131.97%, 128.18% and 102.29% higher respectively than the average for Eucalyptus globulus seedlings; 2） for oil samples obtained from the leaves of the 7 clones, the 1,8-cineole （one of main components of eucalypt leaf essential oil） contents of clones 4, 8, 7 and 1 were 82.85%, 80.31%, 80.26% and 80.05% respectively; 3） by the index of total 1,8-cineole yield obtained from leaves of these clones, the total oil yield rate was the key factor determining productivitY of 1,8-cineole and the oil yield rate showed a direct correlation with production of 1,8-cineole. |
