摘　　要：以红树植物尖瓣海莲幼苗为研究对象,采用盆栽方法,研究丛枝菌根真菌(AMF)侵染后,不同浓度盐胁迫对尖瓣海莲幼苗氮、磷、钾含量的影响。结果表明,盐胁迫抑制尖瓣海莲幼苗对营养元素氮、磷、钾的吸收和积累,接种AMF后能提高幼苗对3种营养元素的吸收和积累,说明AMF对促进幼苗生长和缓解盐胁迫毒害有重要意义。Taking Bruguiera sexangula var. rhynchopetala as the research object, the effects of arbuscular mycorrhizal fungi（AMF） on the concentrations of nitrogen and phosphorus and potassium of mangrove Bruguiera sexangula var. rhynchopetala under salt stress were estimated by using pot-cultivated experiments. Results showed that, the salt stress had inhibited all the absorption and accumulation of nutrient elements N,P,K in Bruguiera sexangula var. rhynchopetala seedlings. However the opposite results could be found in the seedlings after inoculation of AMF. It showed that the AMF could promote seedlingsgrowth and alleviate the destruction of salt stress.
