在柑桔遗传和分类研究中,采用凝胶电泳法检测叶片同功酶,可鉴别大多数柑桔种;但对某些种,采用此技术却难以区别.试验证明,通过叶片挥发油的色谱分析,则能加以鉴别。气相色谱分析挥发油的样品制备,普遍采用蒸气蒸馏,但需大量叶样。另一种样品制备方法,系采用液上气体分析技术.本试验应用载体气体和反相填充材料吸附作用 In citrus genetic and taxonomic studies, gel electrophoresis was used to detect leaf isozymes to identify most citrus species, but for some species, it was difficult to distinguish between these techniques. It was shown that by chromatographic analysis of volatile oils from leaves, , You can identify. Gas chromatographic analysis of volatile oil sample preparation, the general use of steam distillation, but the need for a large number of leaf-like. Another sample preparation method, the use of liquid gas analysis technology.This test uses carrier gas and reverse-phase packing material adsorption
