In a shallow outdoor trough, the growth responses of transplanted <i>C. globularis</i> and <i>E. densa</i> plants were examined over a 12-month period and the germination response of <i>C. globularis</i> oospores over a 5-month period. Under low light, growth of both species, but particularly <i>C. globularis</i>, was poor and no significant differences were observed between sediment types. Under high light, growth of <i>C. globularis</i> plants was strongly inhibited (by 96 and 49%) on the sand and <i>C. demersum</i> sediments relative to the charophyte sediment (320&nbsp;g&nbsp;DM&nbsp;m<sup>&#x2212;2</sup>&nbsp;y<sup>&#x2212;1</sup>). However, germination and short-term (&#60;20 weeks) survival of <i>C. globularis</i> oospores was comparable between sediment types (8&#x2013;12%, no significant differences). Since growth of <i>E. densa</i> was not similarly affected by <i>C. demersum</i> sediment (955, 1051 and 270&nbsp;g&nbsp;DM&nbsp;m<sup>&#x2212;2</sup>&nbsp;y<sup>&#x2212;1</sup> on <i>C. demersum</i>, charophyte and sand sediments), this could indicate higher tolerance of unfavourable conditions associated with organic-rich sediments (inhibitory substances and/or low density substrate) by vascular submerged plants relative to non-vascular species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Responses of vascular (<i>Egeria densa</i>) and non-vascular (<i>Chara globularis</i>) submerged plants and oospores to contrasting sediment types","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"allelopathy; ammonium; angiosperm; Ceratophyllum demersum; charophyte;oospore germination; organic matter; redox potential","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2005-09-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000231866300006","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2005.05.010"},"refs":null,"anarec":{"AnaID":76690,"PubliDate":2005,"Pagination":"141-153","XtraPublOfAnaID":null,"ISBN":null,"Volume":"83","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
