摘　　要：目的:探讨土壤营养元素与栀子苷含量的相关关系。方法:运用HPLC法测定52个产区的栀子苷含量,根据土壤元素相关测定方法分别测出52个产区的11种土壤营养元素含量,将两者测定结果进行相关分析、回归分析,再经通径分析得出营养元素对栀子苷含量的直接作用、间接作用和综合作用。结果:相关分析得出各营养元素之间普遍存在极显著或显著关系;逐步回归分析筛选出有统计意义的3种营养元素,分别是有效铜、有效锰、有效锌;通径分析得出3种营养元素影响栀子苷含量的综合作用值排列顺序依次是有效铜>有效锌>有效锰,其中有效锌产生负相关作用。结论:土壤营养元素与栀子苷含量有一定相关性,经分析所得结果为指导栀子的规范化种植以及提高栀子的品质提供相关参考理论,但栀子生长过程和品质是多种因素互相作用的结果,对其他影响因素的全面分析仍有待于进一步研究。Objective： To study the relationship between soil nutrient elements and the content of geniposide. Method： The HPLC method and the correlation method of soil elements were used to determinate the content of geniposide and the 11 soil nutrient elements in 52 producing areas. The correlation analysis and the regression analysis were conducted to analyze the two test results. A path analysis was conducted to define direct effects,indirect effects and combined effects of nutrient elements on the content of geniposide. Result： The correlation analysis results showed extremely significant or significant relations among the nutritional elements.Three nutrient elements with statistical significance were selected by stepwise regression analysis,namely effective copper,effective manganese,and effective zinc. According to the path analysis,the order of the three nutrient elements in the comprehensive effect on the content of geniposide is effective copper,effective manganese and effective zinc,among them,effective zinc had an effect in negative correlation. Conclusion： Soil nutrient elements and the content of geniposide have a certain correlation. The results of this paper provide the relevant reference theory for guiding standardized cultivation and improving the quality of gardenia. However,as the growth process and quality of Gardeniae Fructus are affected by many factors,the comprehensive analysis on other factors shall be further studied.
