“…During flowering there were no apparent differences between the sites. Chen et al (2005), found similar results under flooded conditions but observed reduced flowering as well as a reduction in seed production. Even though the highest moisture levels observed in this study occurred at or near the time of flowering, we observed no reduction in flowering at the site.…”

Lepidium latifolium is an aggressive plant species that is invading both wetlands and uplands across a wide range of salinities. This study examined how salinity and moisture gradients influence the potential for invasion by L. latifolium. Three sites in the San Francisco Bay Delta with varying salinity and moisture levels were chosen as research sites. These sites corresponded to a dry (18.32%) freshwater (3.88%) site, a wet (40.53%) brackish (23.16%) site, and a moderately wet (38.33%) saline (32.33%) site. Our results showed that inflorescence number and height were unaffected by salinity or soil moisture. Seed production was significantly affected by salinity (P = 0.0297) and moisture levels (P = 0.0004). Seed production at the high salinity site was reduced by 29% from the freshwater site. Seed production at the wettest site had an 87% reduction from the driest site. Seed viability was also reduced by both salinity (P \ 0.0001) and soil moisture (P \ 0.0001). Viability at the highest salinity site was reduced by 49% from freshwater sites and was reduced by 8% from the wettest to driest sites. Mean seed dispersal distance was 0.23 m greater at the freshwater site, which was not statistically significant (P = 0.1815). The deleterious effects of salinity and moisture resulted in reduced L. latifolium densities in high salinity and moisture locations, but only at the highest salinity site. With increased seed production and viability, drier freshwater sites experience greater propagule pressure, resulting in an increased invasion potential. Therefore, variability along salinity and soil moisture gradients serve as useful metrics for prioritizing control and eradication efforts of L. latifolium.

“…C18 showed an increase in the phloem width of 48.2% compared to the variety BR 107 and of 46.2% compared to C1. There is inhibition of photoassimilate transport to the root in plants under flooding conditions (Chen et al 2005). A thicker phloem tissue in the root might be favorable for an increase in the phloem transport from the aboveground parts to the roots.…”

Changes in root anatomical structures at successive cycles of selection (cycle 1 to cycle 18, alternating) were observed in the study of maize (Zea mays L. cv. Saracura-BRS 4154) capable to survive and produce in temporarily flooded soils; this cultivars was developed by the Maize and Sorghum National Research Center through stratified phenotypic recurrent selection for cultivation wetland soils. Field trial was carried out and flooding of the soil was initiated at the six-leaf stage; the soil was flooded with water (20-cm deep) three times per week. Root sample was collected, fixed, and selected for observation in photon microscope. A gradual increase in the number of aerenchyma, the proportion of vascular cylinder, smaller metaxylem, and phloem and epidermis width, and a decrease in exodermis and cortex were observed in successive selection cycles. Such phenotypic changes impart the flood tolerance ability to this maize cultivar.

“…Flooding itself is a stress factor for non-wetland vegetation as it drastically changes physiological functioning of plants, such as photosynthesis, respiration and internal transport of nutrients, due to oxygen deficiency and accumulation of reduced compounds (Chen et al, 2005;Banach et al, 2009a). Herbs, the most abundant plant group on the studied meadows were most sensitive to flooding as could be expected for this terrestrial species group lacking specific adaptations to flooding (Van Eck et al, 2004;Banach et al, 2009a); 8 out of 26 species disappeared.…”

Abstract. Raising safety levees and reinforcing dykes is not a sufficient and sustainable solution to the intense winter and summer floods occurring with increasing frequency in Eastern Europe. An alternative, creating permanently flooded floodplain wetlands, requires improved understanding of ecological consequences. A 9 month mesocosm study (starting in January), under natural light and temperature conditions, was initiated to understand the role of previous land use (fertility intensity) and flooding water quality on soil biogeochemistry and vegetation development. Flooding resulted in severe eutrophication of both sediment pore water and surface water, particularly for more fertilized soil and sulphate pollution. Vegetation development was mainly determined by soil quality, resulting in a strong decline of most species from the highly fertilized location, especially in combination with higher nitrate and sulphate concentrations. Soils from the less fertilized location showed, in contrast, luxurious growth of target Carex species regardless water quality. The observed interacting effects of water quality and agricultural use are important in assessing the consequences of planned measures for ecosystem functioning and biodiversity in river floodplains.
