The results indicated that all these wetland plants decreased pH and concentration of Fe（II） but increased the Eh in the rhizosphere soils. Pb and Zn were transformed from unstable fractions to more stable fractions in the rhizosphere soils, so decreasing their potential metal mobility factors （MF）. Among the four plants, E. macrophyllus, with the highest ROL and root biomass, possessed the greatest ability in formation of Fe plaque and in the reduction of heavy metal MFs in the rhizosphere soil. Wetland plants, with higher ROLs and root biomass, may thus be effective in decreasing potential long-term heavy metal bioavailabilities.展开更多

In the system of plant species, however, the border with the pollen limitation has often been vague in past studies. This study, using field and laboratory experiments and field observations, examined the reproductive success of an endangered native herbaceous plant, Veronica polita lilacina, in the context of the reproductive interference by the alien congener, V. persica. The auto-pollination experiment confirmed that both species can usually produce seeds even without external conspecific pollens. Results of the artificial pollination experiment demonstrated that pollination with the heterospecific pollens significantly decreases the number of seeds in the native species, but not in the alien species. A transplant experiment revealed that the coexistence with the alien species reduced the fruiting success of the native species. Field observations have shown the interaction between two species in the native patch with only one intruding alien species. They demonstrated that native individuals placed closer to the alien individual suffered a greater decrease in fruiting success and the seed production and that the alien intruder produced no seed. These results demonstrate that species that could reproduce via the auto-pollination suffered the reproductive interference and that the native species also exert the resistive reproductive interference slightly. These interactions can explain the displacement pattern of the native species by the alien congener in Japan.展开更多

Antioxidant evaluation was based on the scavenging activity of free radicles (DPPH) and procollagen type 1 protein (P1P) synthesis test was performed in fibroblast cell. Clinical anti-wrinkle activity was performed on female subjects in placebo-controlled trail. Verbascoside (an isolated compound) showed higher (IC50 value of 36.24 ± 1.81 μg/ml) free radicle inhibition activity but weaker collagen synthesis activity. The ethanolic extract showed good inhibition to DPPH free radicals and also showed a significant effect in collagen synthesis activity without cytotoxicity. In the in vivo study, treatment with the formulated cream (Scoti-Speedwell) for 56 days significantly reduced the percentage of wrinkle area and length with 18.0% and 16.05%, respectively. Overall, Veronica officinalis extract containing product (Scoti-SpeedwellTM) can be regarded as a potent anti-wrinkle agent in human skin.展开更多

Vural comb. ＆ stat. nov., previously regarded as a variety, is proposed as a new combination, based on the morphological characters and seed storage protein polymorphism presented in this study. In addition, information about the ecology and conservation status of Veronica erciyasdagi was reported. This taxon is endemic to central Anatolia, Turkey and is critically endangered.展开更多

In hydroponic system, various concentrations of the Cd (50, 100, and 150 ppm) and NaCl salt (1000, 3000, and 6000 ppm) were used alone and in various combinations to evaluate the effect of salt (NaCl) concentrations on Cd absorption and accumulation in Veronica anagallis and Epilobium plants. The Cd at higher concentrations (100 and 150 ppm) significantly reduced the growth and biomass of both plants and addition of salt (NaCl) to growth media (Hoagland solution) further reduced the growth. The Cadmium (Cd) translocation factor (TF) of Epilobium plant was more than one (1), while the Veronica plant showed translocation factor less than 0.5. Veronica plant showed higher Bio-concentration factor (BCF) as more than 3.5 and Epilobium plant demonstrated Bio-concentration factor less than 1 (BCF 1 is a threshold limit for a plant to be hyper-accumulator of Cd). Conclusively, the Veronica anagallis plant is reported as Cd hyper-accumulator, while Epilobium laxum plant as non hyper-accumulator on the basis of BCF values in the present findings. Further study on Veronica and Epilobium plants is recommended.展开更多
