Aerenchyma may supply submerged portions of the plant with atmospheric oxygen as well as lower metabolic demands of the plant. These physiological benefits help to make <i>Spartina</i> grasses formidable invasive species in areas where they have been introduced. Aerenchyma development was investigated in <i>S. alterniflora</i> and <i>S. anglica</i> maintained in greenhouse experiments under flooded and drained soil conditions. Amounts of aerenchyma along the lengths of roots were calculated from digital images of serial root cross-sections using image analysis software. Maximal aerenchyma formation occurred in <i>S. alterniflora</i> following exposure to flooded conditions, while aerenchyma in <i>S. anglica</i> did not increase under the same conditions. Aerenchyma function was investigated by testing individual <i>Spartina</i> plants for their ability to transport oxygen from leaves to roots. Oxygen transport capacities provided information about the plants' oxygen demands and the overall effectiveness of their aerenchyma systems. <i>S. anglica</i> plants were able to transport substantial oxygen to their roots, but no oxygen transport was detected in <i>S. alterniflora</i> plants under the same conditions. Increased aerenchyma formation in flooded <i>S. alterniflora</i> did not enhance oxygen transport and may function primarily in reducing metabolic oxygen demands.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Aerenchyma development and oxygen transport in the estuarine cordgrasses <i>Spartina alterniflora</i> and <i>S. anglica</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:03.968303","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Cordgrass; Invasive species; Aerenchyma","Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2002-10-22","DateCreate":"2002-10-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000178231500002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0304-3770(02)00051-7"},"refs":null,"anarec":{"AnaID":28463,"PubliDate":2002,"Pagination":"109-120","XtraPublOfAnaID":null,"ISBN":null,"Volume":"74","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
