高粱杂交种籽粒中功能元素含量差异及相关性分析

Difference and Correlation Analysis of Functional Elements Content in Grain of Sorghum Hybrids

利用ICP-MS测定了12个高粱杂交种籽粒中的Fe、Zn、Se、Mn等元素含量,进行了品种差异显著性比较和相关性分析,为创制优质的高粱种质资源和组配杂交种提供理论依据。结果表明,在12个杂交种中,晋杂15号4种功能元素的含量普遍较高,其中,Zn、Se、Mn的含量最高,623A×014-33晚和晋杂20号的Fe含量较高,6A×33的Fe、Zn、Se含量较低;不同品种间Zn元素含量差异显著,而Fe、Se、Mn含量的差异未达显著水平;Fe、Zn、Mn和Cu元素间存在极显著正相关,有协同吸收或运输作用,Fe与Se、Cd和As元素间存在负相关,As与Zn和Se间存在极显著正相关。

The contents of Fe,Zn,Se,Mn and other elements in the grains of 12 sorghum hybrids were determined by ICP-MS,and the significant comparison and correlation analysis of varieties were carried out,so as to provide a theoretical basis for creating high-quality sorghum germplasm resources and hybrid varieties.The results showed that among the 12 hybrids,the content of 4 functional elements in Jinza 15 was generally higher,among which the contents of Zn,Se and Mn were the highest,and the content of Fe in 623A×014-33 wan and Jinza 20 was higher,the content of Fe,Zn,Se in 6A×33 were lower.There were significant differences in Zn element content between different varieties,but the difference in Fe,Se,Mn content was not at a significant level.There were significant positive correlation between Fe,Zn,Mn and Cu,indicating that synergistic absorption or transport effect were present among four elements.There was a negative correlation between Fe and Se,Cd and As elements,and there was a very significant positive correlation between As and Zn and Se.
