“…Indeed, the nature of resources stored is partly ruled by the nutrient level of the habitat where the plant has grown (Fischer et al 1995;Améziane et al 1997;Cuzzuol et al 2005;Kavanova and Gloser 2005). For instance, in nutrient-rich habitats, Steinbáchová-Vojtísková et al (2006) demonstrated that Typha individuals tend to store more nitrogen and non-structural carbohydrates, whereas in oligotrophic conditions, individuals of Phragmites accumulate preferably starch (Kubin and Melzer 1996).…”

Abiotic stresses increase plant regeneration ability

In disturbed habitats, vegetative regeneration is partly ruled by plant reserves and intrinsic growth rates. Under nutrient-limiting conditions, perennial plants tend to exhibit an increased allocation to storage organs. Under mechanically stressful conditions, plants also tend to increase allocation to below-ground biomass and storage organs. We tested whether those stresses acting differently on plants (nutrient level versus mechanical forces) led to similar effect on storage organs and regeneration ability. We measured, for an aquatic plant species, (1) the size and allocation to storage organs (stems) and (2) the regeneration ability of the storage organs. Plant stems were collected in 4 habitats ranked along a nutrient stress gradient, and having encountered null versus significant mechanical stress (flowing water). All stems were placed in similar neutral conditions and left for a period of 6 weeks before measuring their survival and growth. Dry mass allocation to the storage organ (stem) was higher in stressful habitats. Moreover, stress encountered by plants before the experiment significantly affected regeneration: stems of previously stressed plants (i.e. plants that had grown in nutrient-poor or mechanically stressful habitats) survived better than unstressed ones. Stems of plants having encountered mechanical stress before the experiment had increased growth in nutrient-rich habitats but reduced growth in the poorest habitats. These results demonstrate that regeneration could rely on the level of stress previously encountered by plants. Stress could lead to greater regeneration ability following mechanical failure. The possible mechanisms involved in these results are discussed.

“…Here the interspecific competitionespecially with Typha angustifolia and Phragmites australis -are more important factors than abiotic environmental conditions. When the nutrient availability is very high -in hypereutrophic conditions -the growth and physiological condition of the nutrientdemanding plants, such as Typha angustifolia can weaken (Steinbachova-Vojtiskova et al, 2006). At present, T. angustifolia is very common and forms large monocultures in the Kokemäenjoki River delta (Suominen, 2013).…”

The growth dynamics of two tall littoral helophytic plants, the narrow-leaved cattail (Typha angustifolia L.) and broad-leaved cattail (Typha latifolia L.; Typhaceae) were studied in the rapidly changing estuarine habitats in the Kokemäenjoki River delta, western Finland. The two cattails form uniform, single-species communities (monocultures) throughout the plant-covered estuary. Of the two taxa compared, the shoots were taller in T. angustifolia (mean 166 cm) than in T. latifolia (mean 120 cm). But due to the robust leaves, the relation in the average weight of individual ramets was opposite: The mean weight of T. angustifolia was 9.6 g (dry wt), and that of T. latifolia was 16.5 g. In a separate study, the leaf height was compared between the fertile (flowering) and sterile (non-flowering) ramets. In flowering ramets the average leaf length was 35 cm taller in Typha angustifolia than in T. latifolia. The differences were even more pronounced in sterile ramets, where the leaves of Typha angustifolia were 70 cm taller than those of T. latifolia. The differences were statistically highly significant. Interspecific competition between the two Typha species is negligible, because the microhabitats differ from each other. T. angustifolia grows in considerably deeper (mean depth 42 cm) waters than T. latifolia (mean depth 19 cm). The optimum range in the water depth is markedly stricter in T. angustifolia than in T. latifolia. The differences between the rooting depths of the two cattails were statistically highly significant. The physico-chemical characteristics of the rooting zones (rhizospheres) of the two cattails are similar, with the locally produced (autochthonous) organic matter dominating and determining the fertility of the habitats.

“…Many authors emphasize the intensification of the succession of common reed in European lakes resulting [7,8], among other things, from the high trophy of waters. Moreover, experimental studies suggest that growth in fertile habitats such as those emerging with Phragmites australis, Typha angustifolia or Typha ssp., is not limited by the high concentration of nutrients [35][36][37].…”

Lake overgrowth is one of the mechanisms affecting the gradual disappearance of lakes in the temperate zone caused by excessive eutrophication of waters. The aim of this study was to assess the possibility of using helophytes as bioindicators of lake overgrowth based on long-term changes based on the cartographic maps studies and field analyses of plant form growth cover (2012)(2013)(2014). Additionally, water and sediment chemistry in overgrowing lakes were investigated. The study comprised a total of 33 eutrophic lakes characterized by varying degrees of vegetation development. Based on discriminant analysis, four groups of lakes with diverse degrees of vegetation growth were distinguished. The group comprising the most overgrown water bodies was found to have the greatest percentage of helophytes, with a considerable proportion of submerged and floating-leaved macrophytes. Based on a review of archival materials, lakes which currently exhibit the highest degree of overgrowth were shown to have been affected by intensive littoral growth for over 100 years, which confirms bioindicator properties of helophytes in the assessment of the degree of lake overgrowth. In addition, lakes with the highest rate of overgrowth were characterized by a high content of nitrogen in sediment, with a concurrent high concentration of potassium.
