Lateral root was 2.43 times longer and 1.97 times denser at low-P than at high-P treatments, while the diameter decreased by 20% when the P application rate was lowered from 4.8 to 0.6 g m<sup>-2</sup> per year. Specific root length (SRL) and specific root area (SRA) of water hyacinth were significantly higher and plant allocated more biomass to lateral root when grown in low-P environments. Although only accounting for 85.35% of total root biomass in condition with low-P availability, lateral roots constituted 99.8% of total root surface area. In natural habitats, plant displayed the same tendency as in experimental tanks. Biomass increased during the experimental period and plant P concentration declined with time under either high- or low-P conditions, the total plant P, however, remained constant at low-P treatment (P>0.05). These results indicate that the variation in lateral roots of water hyacinth can be considerable and the plant can satisfy P requirements for growth by redistribution of internal P source and increase of P absorption capability in low-P waters.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The significance of lateral roots in phosphorus (P) acquisition of water hyacinth (<i>Eichhornia crassipes</i>)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Eichhornia crassipes; lateral roots; morphological plasticity; nutrientacquisition; phosphorus","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-04-01","SecASFANote":"Lateral root morphology and phosphorus intake of <i>Eichhornia crassipes</i> (Donghu L., China)","ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000181681700003","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0304-3770(03)00003-2"},"refs":null,"anarec":{"AnaID":59017,"PubliDate":2003,"Pagination":"311-321","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
