硅對(duì)鉻脅迫下小麥幼苗超微結(jié)構(gòu)和鉻吸收積累的影響摘要：本文旨在研究鉻脅迫下小麥幼苗超微結(jié)構(gòu)和鉻吸收積累的影響。為此，我們采用了具有不同鉻脅迫的Triticumaestivum來分析小麥幼苗超微結(jié)構(gòu)和鉻吸收積累的變化。結(jié)果表明，隨著增加的鉻脅迫水平，小麥幼苗的超微結(jié)構(gòu)發(fā)生變化，表現(xiàn)為根系重量減少和各部位組織活性減少。此外，結(jié)果還顯示，小麥幼苗超微結(jié)構(gòu)和鉻吸收積累之間存在相關(guān)性，且隨著鉻脅迫水平增加，小麥幼苗的鉻吸收積累也會(huì)增加。本研究結(jié)果表明，鉻脅迫對(duì)小麥幼苗超微結(jié)構(gòu)和鉻吸收積累有一定的影響，為促進(jìn)小麥耐鉻脅迫性的提高提供了參考。
