“…Plant species are often limited by multiple stress factors operating simultaneously LENSSEN et al, 2003;SILVA et al, 2016) such as soil salinity and waterlogging (GARCÍA; MENDOZA, 2014;SINGH, 2015), and plant response in these cases can be a consequence of amplified or hierarchical effects (LENSSEN et al, 2003). The results of the present work suggest that the effect of a stress factor depends on the level of the other factor to which the plant is subjected.…”

Soil salinization is a problem commonly found in semi-arid regions. In addition, the problem of salinity is aggravated in clayey soils when accompanied by cycles of waterlogging in the rainy season or when excess irrigation is applied. In this work we evaluated the isolated and combined effects of soil salinity and waterlogging on the responses of young plants of 'Green Dwarf' coconut. The experiment was conducted under controlled environment in a complete randomized block design, arranged in split plots with five replications. The plots comprised five waterlogging cycles (0, 1, 2, 3 and 4), each with a duration of four days, and applied at 30, 60, 90 and 120 days into the experimental period, with the sub-plots consisting of five levels of soil salinity (1.70, 11.07, 16.44, 22.14 and 25.20 dS m -1 ). Response of coconut seedlings to waterlogging was dependent on the level of soil salinity, with waterlogging significantly impairing biomass accumulation and leaf expansion at low soil salinity levels, but causing no additional harm at elevated salinity. Leaf gas exchange was reduced mainly due to soil salinity, and this response was related to stomatal and non-stomatal effects. Seedlings of 'Green Dwarf' coconut used in this study were classified as moderately-tolerant to salinity when grown in soils with an electrical conductivity up to 11.07 dS m -1 , having the potential to be used in revegetation programs of salt-affected areas, provided that these areas are not exposed to frequent waterlogging cycles. ResumoA salinização dos solos é um problema comumente encontrado em regiões semiáridas. Além disso, nos solos mais argilosos, o problema da salinidade vem acompanhado de ciclos de encharcamento do solo, no período de chuvas ou no caso de irrigação excessiva. Neste trabalho, avaliamos os efeitos da salinidade do solo e do encharcamento, de maneira isolada e combinada, nas respostas adaptativas de plantas jovens de coqueiro-anão-verde. O experimento foi conduzido em ambiente protegido, sob delineamento estatístico de blocos casualizados, arranjados em parcelas subdivididas com cinco repetições. As parcelas foram constituidas por cinco ciclos de encharcamento (0, 1, 2, 3 e 4), com duração de quatro dias cada, aos 30, 60, 90 e 120 dias do período experimental e as subparcelas foram constituídas por cinco níveis de salinidade do solo (1,70; 11,07; 16,44; 22,14 e 25,20 dS m -1 ). As respostas das mudas de coqueiro ao encharcamento dependeram do nível de salinidade do solo, os quais reduziram significativamente o acúmulo de biomassa e a expansão foliar em baixos níveis de salinidade do solo. Contudo, os níveis de encharcamento não causaram danos adicionais sob elevados níveis de salinidade. As trocas gasosas foliares foram reduzidas principalmente devido à salinidade do solo, e esta resposta pode estar relacionada aos efeitos estomáticos e não estomáticos. As mudas de coqueiro 'Anão Verde' utilizadas neste experiment foram classificadas como moderadamente tolerantes à salinidade, quando cultivadas em solos...

“…Moreover, our results also confirm that the below-ground mass fraction was much higher in the waterlogged treatments than in drained treatments. In waterlogged sediments, roots of both tolerant and intolerant species may serve as a carbohydrate sink and thus inhibit the investment in the above-ground plant organs (Lenssen et al, 2003), which might be beneficial to plants in preventing oxygenation of the entire root system, as has been ) and two water levels (0 cm and -40 cm, waterlogged and drained conditions). Different letters indicate significant differences between treatments at the 0.05 significance level.…”

“…Waterlogging could inhibit plant growth mainly due to the reduced oxygen availability and redox potential (Eh) in the sediment (Deegan et al., 2007;Li et al, 2011). Generally, plants can acclimatize to waterlogged conditions through various morphological adaptations, such as increased allocation to roots, decreased root length, and formation of aerenchyma (Loreti and Oesterheld, 1996;Lenssen et al, 2003;Xie et al, 2008). These adaptations allow plants to acclimatize to anaerobic conditions by increasing oxygen transport to roots or by reducing radial oxygen loss to the sediment (Luo and Xie, 2009).…”

Competition between two wetland macrophytes under different levels of sediment saturation

Plant-plant interactions have been widely studied under various environmental conditions. However, in wetland ecosystems how plant interactions change in response to brevicuspis densities. Above-ground relative neighbor effect index (ARNE) and relative neighbor effect index (RNE) of C. brevicuspis on P. hydropiper increased along with enhanced C. brevicuspis density only under waterlogged conditions. The below-ground relative neighbor effect index (BRNE) was not affected at the different water level and density treatments. The below-ground mass fraction of P. hydropiper was much higher in the waterlogged treatment than it was inthe drained one, especially with no C. brevicuspis treatment. However, the leaf mass fraction displayed the opposite pattern. The longest root length of P. hydropiper was much shorter under waterlogged treatment than under the drained treatment. These results suggest that the competition intensity of C. brevicuspis to P. hydropiper increased along with increasing C. brevicuspis density only under waterlogged conditions. Moreover, this study also confirms that P. hydropiper can acclimate to water stress mainly through modulating its root architecture, for example reducing the root system length or increasing the root mass fraction.

“…Stress sensu Grime [1] induced by periodic anaerobic conditions [8,12,47] inhibited the growth and development of plants already present and, primarily, impeded recruitment of new individuals of species characteristic of variable-moist meadows, e.g. Cirsium rivulare, Filipendula ulmaria and Lythrum salicaria, which were replaced by Carex acutiformis.…”

“…Given the most common effects of anthropogenic transformation of wet habitats, a substantial number of publications are focused on the impact of desiccation on changes occurring at the level of vegetation, population, and soil seed bank [2][3][4][5]. Seasonal floods and prolonged waterlogging caused by stagnation of water in the catchment area are equally important factors exerting a considerable effect on species dynamics and vegetation of hydrogenic areas [6][7][8][9].…”

Soil waterlogging is among abiotic stresses that influence species composition and productivity in numerous plant communities. The aim of the study was to find answer to the question of how waterlogging caused by beavers' activity induces quantitative and qualitative changes of vegetation and soil seed bank levels of variable-moist meadows.An immediate effect of the waterlogging at the level of vegetation was the decline in species richness and a decrease in the values of the biodiversity index. Water stress inhibited growth and development of plants already present and, primarily, impeded recruitment of new individuals of species characteristic of variable-moist meadows, e.g. Cirsium rivulare, Filipendula ulmaria and Lythrum salicaria, which were replaced by Carex acutiformis. Prolonged waterlogging did not induce equally substantial changes in the soil seed bank as in the vegetation. Both in the waterlogged and control patches, slightly decreased species richness and biodiversity index were recorded. After waterlogging withdrawal, the reserves of the soil seed bank were slightly higher than the initial values. The differences were not statistically significant.In the waterlogged patch, the qualitative floristic similarity between taxa identified in the soil seed bank and vegetation cover declined, which was evidenced by the value of Jaccard's index decreasing from 0.46 to 0.36. A reverse relationship was found in control patch, where the value of the similarity index slightly increased from 0.41 to 0.48.
