摘要:

为研究余甘子不同器官中19种无机元素的分布规律,利用电感耦合等离子体发射光谱仪(ICP-OES)测定干热河谷区余甘子不同器官(根、茎、叶、果实、种子)中19种无机元素含量,并对其进行单因素方差分析、相关性分析、聚类分析和因子分析。结果表明,供试所有余甘子器官样品中均检出B、Cu、Fe、Mg、Mn、Ni、Zn、Ca、K、Na、P、S共12种元素;Se、Si、Co、Cr、Pb、Cd、Mo仅在个别器官样品中检出。不同器官中B、Cu、Fe、Mg、Mn、Ni、Zn、Ca、K、Na、P、S元素含量均存在极显著性差异(P<0.01),且存在极大值和极小值的特征。元素含量之间存在显著或极显著正(负)相关关系。B、Cu、Fe、Mg、Mn、Ni、Zn、Ca、K、Na、P、S共12种无机元素可将余甘子不同器官分为3类,种子、茎、叶片聚为第一类,果实为第二类,根为第三类。Fe、Na、Zn、Cu、Ca和B元素是余甘子不同器官中的特征性元素。表明不同器官对不同元素的吸收和分配具有一定选择性,无机元素之间存在相互作用。

Abstract:

The contents of 19 inorganic elements in different organs (root, stem, leaf, fruit, and seed) of Phyllanthus emblica in dry-hot valley area of Jinsha River were determined by Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). The distribution law of the 19 inorganic elements in different organs of P. emblica was studied by one-way ANOVA, correlation analysis, cluster analysis and factor analysis. The results showed that 12 elements (B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P and S) were detected in all P. emblica samples tested. However, Se, Si, Co, Cr, Pb, Cd and Mo were only detected in individual organ samples. The contents of elements B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P, S in different organs were significantly different (P<0.01), and had the characteristics of maximum and minimum values. Significant or extremely significant positive (negative) correlation existed between the contents of the 12 elements. Different organs of P. emblica could be divided into three categories by these 12 inorganic elements (B, Cu, Fe, Mg, Mn, Ni, Zn, Ca, K, Na, P and S). Among them, seed, stem and leaf clustered into the first type, fruit was the second type, and root was the third type. Fe, Na, Zn, Cu, Ca and B were the characteristic elements in different organs of P. emblica. The results indicate that different organs have certain selectivity on the absorption and distribution of different elements, and there are interactions between inorganic elements.
