The experiment of prolonged submergence was performed in field conditions with two treatment levels; 50% inundation (control) and 100% inundation levels. The experiment of soil water stress was conducted in a plant-house with four treatment levels, 100% water holding capacity (WHC) (control), 50% WHC, 25% WHC and high salinity (> 35 psu). The experimentation period was 18 months. According to the results, antioxidant activity was increased in the 100% inundation level in field conditions and in the 25% WHC, 50% WHC and high salinity levels in plant-house conditions. However, decreased radical scavenging capacity reflected by low 2,2-diphenyl-1-picrylhydrazyl (DPPH) and high IC<sub>50</sub> values were only observed in the 25% and 50% WHCs. Plant cell membranes were highly damaged in the 25%, 50% WHCs and high salinity level and a significant decrease in photosynthetic capacity (~ 90% reduction) and in dry matter content of <i>Rhizophora</i> plants were also observed in the same treatment levels. It was recorded that a higher proportion of dry matter is allocated to the root system under the 100% inundation level and it may be an adaptation to keep up the standing stability. Although, the antioxidant and scavenging capacities of young <i>Rhizophora</i> plants have increased under abiotic stress conditions, oxidative stress and its associated impacts on leaf photosynthetic capacity and dry weight contents were unavoidable under persistence of the stress.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Oxidative stress, leaf photosynthetic capacity and dry matter content in young mangrove plant <i>Rhizophora mucronata</i> Lam. under prolonged submergence and soil water stress","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":"Mangroves; Reactive oxygen species; Antioxidants; Scavenging capacity; Dysfunction; Survivorship","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-05-31","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000549656500001","VABBcode":null,"OpenAcc":0,"Handle":"10.1007/s12298-020-00843-w"},"refs":null,"anarec":{"AnaID":337762,"PubliDate":2020,"Pagination":"1609-1622","XtraPublOfAnaID":null,"ISBN":null,"Volume":"26","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":276413,"SerRR":"Physiology and Molecular Biology of Plants.
