| 摘 要： | 采用控制浇水量的方法设计土壤(相对含水量为低44.46%±1.22%~52.84%±2.34%）、中（59.75%±3.11%~77.85%±3.47%）、高（75.24%±3.24%~99.27%±5.67%）3个范围，研究土壤含水量对茴香生长与精油含量及其组分的影响。结果表明，随着土壤含水量的升高，茴香株高、植株节数、根干质量、地上部干质量、全株干质量、全碳含量、单株精油产量和叶绿素a/叶绿素b均随之升高，而根冠比、全氮含量、蛋白氮含量、叶绿素a含量、叶绿素b含量和类胡萝卜素含量均随之下降；中土壤含水量的植株花序数、精油含量和可溶性糖含量较高，低和高土壤含水量的则较低；不同土壤含水量处理茴香植株，其精油共鉴定出22种成分，除α-蒎烯、香桧烯、β-蒎烯、γ-萜品烯、萜品油烯、肉豆蔻醚6种成分相对含量差异不显著外，其余16种成分相对含量均表现出显著或极显著差异；随着土壤含水量的增大，精油的第一主要成分反式—茴香脑含量呈升高趋势，低、中、高3个含水量处理的含量依次为41.34%、53.87%和62.97%，第二主要成分柠檬烯含量与反式—茴香脑含量变化相反，其3个含水量处理依次为44.77%、34.77%和22.16%。因此，低土壤含水量处理相对有利于茴香柠檬烯的积累，而高土壤含水量处理相对有利于反式-茴香脑的积累。

| Abstract: | Effects of soil water on plant growth, contents and components of essential oil in fennel were studied , by controlling soil water content at low (relative water content, 44.46%±1.22%~52.84%±2.34%), middle (relative water content, 59.75%±3.11%~77.85%±3.47%) and high (relative water content, 75.24%±3.24%~99.27%±5.67%) levels. The results showed that, with increasing of soil water content , plant height, number of node, root and shoot fresh weight(FW), plant FW, content of total carbon, yield of essential oil per. plant and Chl.a/Chl.b ratio were elevated, but root/shoot ratio, contents of total nitrogen, proteinic nitrogen, Chl.a, Chl.b and CAR were decreased; Number of inflorescence, contents of essential oil and solubility sugar were higher in middle level water treatment, while they were lower in low and high level water treatments; Twenty-two chemical compounds were also identified in different soil water treatments, relative content was no difference (α=0.05) in α-Pinene, Sabinene, β-Pinene, γ-Terpinene, Terpinolen and Myristicin, but was significant ( α=0.05,0.01) in other sixteen compounds; With increasing water content , content of (E)-anethole, the dominant component in essential oil, was enhanced at 41.34%, 53.87% and 62.97%; Limonene was the second abundant material in oil, its content was decreased at 44.77%, 34.77% and 22.16%. This study indicated that lower water content had a positive role in accumulation of Limonene, and higher water content was relatively favour for storage of (E)-anethole in fennel. |
