外源施硒对金银花植株金属元素分布的影响
Effect of exogenous application of selenium on the distribution of metal elements in honeysuckle plants
摘要
Abstract
Objective To explore the effects of exogenous selenium application on the appearance and morphology of honeysuckle flower buds and the absorption and transfer of selenium in honeysuckle plants,in order to provide a scientific basis for the application of selenium fertilizers in medicinal plants such as honeysuckle.Methods Different concentrations of sodium selenite were sprayed on the leaves of honeysuckle,and the contents of metal elements in honeysuckle plants after selenium application were determined by inductively coupled plasma mass spectrometry(ICP-MS).Results When the concentration of sodium selenite was low(0～50 mg·L-1),the appearance and morphology of honeysuckle flower buds were normal,while at high concentrations(100～300 mg·L-1),there was a certain degree of scorching on the flower buds.Appropriate concentrations(20～50 mg·L-1)of sodium selenite could promote the absorption of beneficial elements such as calcium,magnesium,iron,zinc,and manganese.At different treatment times(6,12,18,and 24 days),with the increase of sodium selenite concentration,the selenium content in the roots,stems,and leaves of honeysuckle significantly increased.Notably,except for the lead content in the roots of honeysuckle being slightly higher at 20 mg·L-1,the contents of heavy metal elements such as lead,cadmium,chromium,arsenic,and copper in different parts of honeysuckle plants were all lower than those in the blank group,indicating that sodium selenite could inhibit the absorption of heavy metals.Conclusion This study provides a scientific basis for the application of selenium fertilizers in medicinal plants such as honeysuckle.Appropriate concentrations of sodium selenite can not only promote the absorption of beneficial elements but also effectively control heavy metal pollution,which is of great significance for improving the quality and safety of medicinal plants.关键词
