Plants were grown in pots in monoculture (three monocultures) and one mixture of the three species, under two different watering regimes: low watering frequency (LWF) and high watering frequency (HWF) corresponded to watering each four-six or two-three days, respectively, depending on the daily evapotranspiration demand. The responses to water stress in leaves were assessed by quantifying the content of chloroplastic pigments (chlorophylls and carotenoids) and the oxidation state (by measurements of ascorbate and dehydroascorbate). Prior to irrigation, all three species were more stressed as compared to after irrigation. LWF was always more damaged showing significant differences between watering treatments and indicating that future Mediterranean conditions will be more oxidative for the montado species. There were no pronounced differences between monoculture and mixtureISA/ULPintó-Marijuan, MartaCorreia, Alexandra Cristina PiresRepositório da Universidade de LisboaBicho, Maria Catarina Gomes Pedro2014-11-04T10:28:34Z20142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.5/7401TID:201921120engBicho, M.C.G.P. - Different water regimes effects on photoprotection strategies of three species from montado understorey: a pot experiment.
