Trin. Ex Steudel), a species potentially susceptible to salinity. We measured dry weight and <i>δ</i><sup>13</sup>C of <i>P. australis</i> transplanted in a constructed saline wetland four times between July 2001 and May 2002. Shoot dry weight (590–3090 g m<sup>−2</sup>) of <i>P. australis</i> was negatively correlated with rhizosphere salinity. Shoot <i>δ</i><sup>13</sup>C values (−27.1 to −23.8‰) in the saline wetland were less negative than that of control samples (−28.7 to −28.2‰) collected from non-saline riparian zones nearby. In addition, the <i>δ</i><sup>13</sup>C values became less negative, indicating decreased carbon isotope discrimination, as salinity increased. These results are consistent with published gas exchange measurements that showed that salinity stress could decrease CO<sub>2</sub> diffusion rate by reducing stomatal and/or mesophyll conductance. However, we could not preclude the possibility of growth reduction caused by salinity effects on carboxylation. We suggest that the non-destructive and time-integrating <i>δ</i><sup>13</sup>C measurement is a useful tool in monitoring responses of <i>P. australis</i> to environmental conditions in saline wetlands.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Carbon isotope composition of <i>Phragmites australis</i> in a constructed saline wetland","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-17 01:32:09.615177","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"carbon isotope discrimination; common reed; constructed wetland; salinewater; salinity stress","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2020-10-07","DateCreate":"2005-07-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000230046300003","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":74905,"PubliDate":2005,"Pagination":"27-38","XtraPublOfAnaID":null,"ISBN":null,"Volume":"82","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
