The experiment of potted was carried out in the green house and biao-ben orchard of Shandong Agricultural University from 2002.9~2003.6. Aroma components of fruit were extracted by solvent soluble and analyzed by Gas Chromatogram/ Mass Spectrum , to study on the effect on strawberry aroma component under various nitrogen levels. At the same time , glucose and fructose in fruit were analyzed by High Performance Liquid Chromatography, and the correlation between glucose、 fructose and the precursor of strawberry characteristic aroma component was studied according the former article.

本试验于2002年9月~2003年6月分别在山东农业大学日光温室和果树标本园中进行，采用盆栽的方式，用溶剂萃取法提取香气成分，用气相色谱-质谱联用仪进行定性、定量分析，研究了不同氮素水平对草莓果实芳香成分的影响，同时采用高效液相色谱法测定果实葡萄糖、果糖含量，对果实中葡萄糖、果糖与草莓特征香气成分前体之间的关系进行了初步探讨。

Measurement of Ligninolysis The delignification of a solid lignocellulosic substrate is often assessed by the simple procedure of removing its low molecular weight components by extraction, weighing the leftover woody residue, degrading the remaining polysaccharide component with strong acid, and then reweighing the leftover insoluble lignin, which is chemically modified and referred to as Klason lignin.
