摘要
利用小麦水培安验，研究了从土壤中提取的富啡酸（Ｆｕｌｖｉｃａｃｉｄ，ＦＡ）对亚硒酸钠生物有效性及毒性的影响。结果表明，富啡酸对小麦吸收利用亚硒酸钠有明显的影晌，并且对高浓度亚硒酸钠的毒性有一定的抑制作用，富啡酸可提高小麦对硒胁迫的生态适应性。
Influence of Fulvic acid (FA) on bioavailability and toxicity of selenite to wheatseedling is studied by greenhouse hydroponical experiment. The results showed that FA from soil inhibites the absorption of selenium from culture media. The antagonism effects betweenFA and selenium has been observed in terms of various of physiological and biochemical measurements. FA enhances also the ecological adaptability of wheat to high selenium stress.
