Despite these improvements, seagrass leaf growth can be difficult to measure effectively; current methods are destructive to the plants and require at least two site visits per growth period. We used the “previous growth” of Ibarra-Obando and Boudouresque [Ibarra-Obando, S.E., Boudouresque, C.F., 1994. An improvement of the Zieman leaf marking technique for <i>Zostera marina</i> growth and production assessment. Aquat. Bot. 47, 293–302.] to develop a relationship between sheath length and leaf growth in eelgrass, <i>Zostera marina</i> L., and we demonstrated that a simple, non-destructive method allows reliable calculation of eelgrass leaf growth (mg shoot<sup>−1</sup> day<sup>−1</sup>) based on sheath length. We measured eelgrass sheath length and leaf growth for 18 months, from November 1999 to April 2001, at a site in Portsmouth Harbor on the border of New Hampshire and Maine, USA. Regression analyses showed a high coefficient of determination between sheath length and leaf growth, demonstrating that sheath length reliably reflected eelgrass leaf growth. We also showed that four seasonal measurements were sufficient to establish a significant relationship between sheath length and leaf growth. After a regression of sheath length and leaf growth has been established for a site, eelgrass sheath length can be measured in situ to accurately calculate leaf growth, eliminating both the need for destructive growth measurements and the need to mark and relocate plants.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sheath length as a monitoring tool for calculating leaf growth in eelgrass (<i>Zostera marina</i> L.)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:12.453451","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"seagrass; growth; plastochrone; productivity sheath length; monitoring","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2020-10-19","DateCreate":"2006-03-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000235861300006","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2005.10.006"},"refs":null,"anarec":{"AnaID":97075,"PubliDate":2006,"Pagination":"226-232","XtraPublOfAnaID":null,"ISBN":null,"Volume":"84","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
