微量元素在小麦植株不同器官的富集和转运特征
Enrichment and Transport Characteristics of Trace Elements in Different Organs of Wheat Plants
摘要
Abstract
The distribution characteristics of trace elements in wheat were analyzed in order to provide scientific basis for scientific regulation of trace element content in wheat and cultivation of new wheat varieties.The distribution characteristics of trace elements,including iron(Fe),manganese(Mn),copper(Cu)and zinc(Zn)in different organs of wheat at maturity stage were analyzed by using wheat varieties popularized in large area in northern Henan as experimental materials.The content of Fe in wheat plants ranged from 42.31 to 80.66 mg/kg,the content of Mn ranged from 212.11 to 604.89 mg/kg,the content of Cu ranged from 12.31 to 16.35 mg/kg,and the content of Zn ranged from 48.77 to 87.08 mg/kg.The variation coefficients of Fe,Mn,Cu,Zn contents in roots,stems,leaves,glume and grains of wheat plants showed different rules.The order of Mn enrichment ability of different organs of wheat was leaf>root>grain>stem>glume,and the order of Cu and Zn enrichment ability was root>grain>leaf>stem>glume.The order of Fe,Cu and Zn transport capacity of wheat organs was grain>leaf>stem>glume,and the order of Mn transport capacity was leaf>grain>stem>glume.The order of enrichment ability of trace elements in wheat roots,stems,glume and grains was Zn>Cu>Mn>Fe,and the order of enrichment ability of trace elements in leaves was Mn>Zn>Cu>Fe.The transport capacity of trace elements Cu,Mn,Zn in stems,leaves and glume of wheat was greater than that of Fe,and the order of transport capacity of trace elements in grains was Zn>Cu>Fe>Mn.The results of correlation analysis showed that there was a significant interaction between trace elements.The distribution of trace elements in wheat plants in northern Henan showed a vertical distribution pattern.The enrichment ability of trace elements in roots,leaves and grains was strong,and the transport ability of trace elements in leaves and grains was strong.关键词
