Fe元素与山茱萸产量及品质的相关性研究

Correlation Study on Iron Content, Yield and Quality of Cornus officinalis

目的:研究山茱萸叶片中Fe元素含量与其产量及品质的相关性。方法:采用微波消解-火焰原子吸收光度法测定山茱萸叶片中Fe元素含量,果实中马钱苷与熊果酸含量采用HPLC法测定,同时对叶片中Fe元素含量与果实产量、马钱苷及熊果酸含量之间的关系进行相关性分析。结果:不同产量水平的山茱萸叶片中Fe元素含量不同,且与果实产量及品质有着一定的相关性。结论:该研究可改善山茱萸源库关系,进而调节源库平衡,指导药农掌握喷施Fe肥时期,以提高山茱萸的产量与品质。

This article was aimed to study the correlation between iron content in Cornus officinalis leaves and its yield as well as quality. The method of microwave digestion atomic absorption spectrophotometer was used to determine the content of iron element in Cornus officinalis leaves. HPLC was used to determine the content of loganin and ursolic acid in fruits. Correlation analysis was made among the content of iron element, yield of fruits, loganin and ursolic acid in fruits. The results showed that iron element in leaves of different yield level cornus officinalis was different. It also had some correlation with yield and quality of fruits. It was concluded that the research can improve relations of source-sink in Cornus officinalis, adjust source-sink balance, guide farmers to master the period of spraying iron fertilizer, and increase production and quality of Cornus officinalis.
