“…In this case, a twofold value of the R D in flooded condition indicated that higher energy expenditure was applied to maintain the metabolism in response to soil flooding. Chl fluorescence has been widely used to reveal the responses of plants to environmental stresses (Maxwell andJohnson 2000, Mauchamp andMéthy 2004). In our study, we did not find any differences in fluorescence parameters between the two experimental conditions.…”

Gas exchange of Carex cinerascens was carried out in Swan Islet Wetland Reserve (29°48′ N, 112°33′ E). The diurnal photosynthetic course of C. cinerascens in the flooded and the nonflooded conditions were analyzed through the radial basis function (RBF) neural network approach to evaluate the influences of environmental variables on the photosynthetic activity. The inhibition of photosynthesis induced by soil flooding can be attributed to the reduced stomatal conductance (g s ), the deficiency of Rubisco regeneration and decreased chlorophyll (Chl) content. As revealed by analysis of artificial neural network (ANN) models, g s was the dominant factor in determining the photosynthesis response. Weighting analysis showed that the effect of water pressure deficit (VPD) > air temperature (T) > CO 2 concentration (C a ) > air humidity (RH) > photosynthetical photon flux density (PPFD) for the nonflooded model, whereas for the flooded model, the factors were ranked in the order VPD > C a > RH > PPFD > T. The different photosynthetic response of C. cinerascens found between the nonflooded and flooded conditions would be useful to evaluate the flood tolerance at plant species level.

“…This did not result from lowered chlorophyll contents that were not affected under the stress conditions. Rather, the photosynthetic capacity of the reed plants should have been inhibited by waterlogging effects (Mauchamp and Mé thy, 2004) and do to the increasing salinity (Lissner et al, 1999b;Pagter et al, 2009;Wang et al, 1998). Whereas photosynthetic activity certainly is one of the major factors controlling growth (Ashraf, 2004;Shannon, 1998;Tezara et al, 2002), the CO 2 assimilation rate measured here did not show a correlation with shoot growth of P. australis under the given cultivation conditions.…”

“…Phragmites australis is a worldwide occurring emergent macrophyte characteristic of the ecotone between terrestrial and aquatic environments in freshwater to brackish wetlands (Mauchamp & Méthy, 2004). It exhibits wide tolerance to flooding and drainage (Hudon, Gagnon, & Jean, 2005) with the ability of phenotypic plastic responses (Vretare, Weisner, Strand, & Graneli, 2001).…”

Environmental conditions in wetlands were long thought to suppress mycorrhizal fungi and it has been assumed that mycorrhiza in wetlands is limited and is of little significance. This contribution summarises the presence of arbuscular mycorrhizal (AM) fungi and dark-septate endophytes (DSE) in different habitats of the intermittent Lake Cerknica. Mycorrhizal colonisation of wetland plants from the following wetland habitats was analysed: (1) frequently inundated small depressions in the lakebed colonised by amphibious plants; (2) P. australis stands covering large parts of the lake area; and (3) wet meadows surrounding the lake area colonised by different Schoenus species. All of the examined amphibious species were found to be mycorrhizal, however terrestrial shoots were more mycorrhizal than aquatic shoots. In the former mycorrhizal frequency F% was up to 100% and mycorrhizal intensity M% up to 67%, while F% was up to 80% and M% up to 16% in the latter. Mycorrhizal colonisation of P. australis with AM and DSE fungi was confirmed in plants growing in different soils and water regimes (17% < F% < 50%; 0.6% < M% < 3%). In the two Schoenus species, F% was up to 99% and M% was up to 14%. According to the literature this is the first detailed report on the presence of AM and DSE mycorrhiza in S. ferrugineus and S. nigricans.
