High plant density caused a reduction of 30% in height, 82% in stem dry mass, 80% in leaf dry mass, and 95% in root dry mass. High density also induced a pronounced 72% reduction in leaf area, 29% decrease in length of mature internodes and 50% decline in net photosynthetic rate. The alteration of net photosynthesis paralleled growth inhibition, decreasing from 7.6 ± 0.9 μmol CO<sub>2</sub> m<sup>−2</sup> s<sup>−1</sup> at low density to 3.5 ± 0.4 μmol CO<sub>2</sub> m<sup>−2</sup> s<sup>−1</sup> at high density, indicating growth inhibition caused by intraspecific competition is mainly due to a decline in net photosynthesis rate. Plants grown at high density also exhibited a reduction in stomatal conductance from 0.7 ± 0.1 mol H<sub>2</sub>O m<sup>−2</sup> s<sup>−1</sup> at low density to 0.3 ± 0.1 mol H<sub>2</sub>O m<sup>−2</sup> s<sup>−1</sup> at high density and a reduction in transpiration rate from 6.0 ± 0.3 mmol H<sub>2</sub>O m<sup>−2</sup> s<sup>−1</sup> at low density to 4.3 ± 0.3 mmol H<sub>2</sub>O m<sup>−2</sup> s<sup>−1</sup> at high density. Biomass production was inhibited by an increase in plant density, which reduced the rate of photosynthesis, stomatal conductance and leaf area of plants.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of intraspecific competition on growth and photosynthesis of <i>Atriplex prostrata</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:31:20.781841","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2020-10-15","DateCreate":"2005-10-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000232564100003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2005.06.005"},"refs":null,"anarec":{"AnaID":77324,"PubliDate":2005,"Pagination":"187-192","XtraPublOfAnaID":null,"ISBN":null,"Volume":"83","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
