Titre : Ecological niche shifts affect the potential invasive risk of Phytolacca americana (Phytolaccaceae) in China Type de document : Imprimé Auteurs : Yifeng Xu ; Xingzhuang Ye ; Huiying Weng ; Yipeng Liu ; Sagheer Ahmad ; Guofang Zhang ; Qiuliang Huang ; Tianyu Zhang ; Bao Liu Année de publication : 2023 Article en page(s) : 1 Langues : Français (fre) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Phytolacca americana L., 1753 Résumé : Background : Predicting the potential habitat of Phytolacca americana, a high-risk invasive species, can help provide a scientific basis for its quarantine and control strategies. Using the optimized MaxEnt model, we applied the latest climate data, CMIP6, to predict the distribution of potential risk zones and their change patterns for P. americana under current and future (SSP126, SSP245, SSP585) climate conditions, followed by invasion potential analysis. Results : The predictions of MaxEnt model based on R language optimization were highly accurate. A significantly high area of 0.8703 was observed for working characteristic curve (AUC value) of subject and the kappa value was 0.8074. Under the current climate conditions, the risk zones for P. americana were mainly distributed in Sichuan, Chongqing, Guizhou, Hunan, and Guangxi provinces. The contribution rate of each climatic factor of P. americana was calculated using the jackknife test. The four factors with the highest contribution rate included minimum temperature of coldest month (bio6, 51.4%), the monthly mean diurnal temperature difference (bio2, 27.9%), precipitation of the driest quarter (bio17, 4.9%), and the warmest seasonal precipitation (bio12, 4.3%). Conclusion : Under future climatic conditions, the change in the habitat pattern of P. americana generally showed a migration toward the Yangtze River Delta region and the southeastern coastal region of China. This migration exhibited an expansion trend, highlighting the strong future invasiveness of the species. Based on the predictions, targeted prevention and control strategies for areas with significant changes in P. americana were developed. Therefore, this study emphasizes the need of an integrated approach to effectively prevent the further spread of invasive plants.

Titre : Seed germination of american pokeweed (Phytolacca americana). I. Laboratory techniques and autotoxicity Type de document : Imprimé Auteurs : Maurice E. Edwards ; Elizabeth M. Harris ; Frederic H. Wagner ; M. Catherine Cross ; Gregory S. Miller Année de publication : 1988 Article en page(s) : 1794-1802 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Phytolacca americana L., 1753 Résumé : Seeds of pokeweed (Phytolacca americana L.), an underinvestigated species, were studied to determine optimal conditions for laboratory germination. Soaking seeds in acid solutions prior to sowing increased rates of germination. Concentrated (conc) H2SO4 was more effective than conc NO3 or conc HCl acids. Physiological evidence from seed germination studies suggests that autotoxicity, or intraspecific inhibition, exists in pokeweed, a species known to possess several biologically active compounds. Seed germination was investigated in the laboratory with aqueous extracts of vegetative and reproductive structures of the plant. The presence of extracts from most plant parts correlated with reduced or no germination by seeds of its own species, whereas the presence of distilled water correlated with high percentages of germination by control seeds. Whether diluted with water by 5-fold (20% v/v) or undiluted, juice of pokeweed fruits completely inhibited the laboratory germination of pokeweed seeds. Also, extracts of freshly harvested mature leaves, stems, and immature fruits inhibited seed germination. However, results with root extracts, obtained from a single individual, depended more on concentration, since the highest concentration (50% v/v) inhibited germination, and lower concentrations (10 and 20% v/v) increased germination percentages over control samples. Results with extracts of juvenile leaves correlated with neither inhibition nor promotion of germination. Thus, except for juvenile leaves and the root, most extracts of the pokeweed plant inhibited seed germination with more mature structures exerting more inhibition and less mature structures exerting less or no inhibition. The ecological implication of autotoxicity is that seeds are more dispersed through time and space. In regard to seed germination by other species, especially those taxa known to possess biologically active compounds, these and other results suggest that the phenomenon of autotoxicity might be more widespread than previously suspected.

Titre : Seed germination of invasive Phytolacca americana and potentially invasive P. acinosa Type de document : Imprimé Auteurs : Simona Strgulc Krajšek ; Aleš Kladnik ; Sara Skocir ; Martina Bacic Année de publication : 2023 Article en page(s) : 1052 Langues : Français (fre) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Phytolacca americana L., 1753 Phytolacca acinosa Résumé : Phytolacca americana and P. acinosa are alien plant species in Europe. The former is considered invasive and more widespread. In order to develop effective and safe eradication and plant disposal methods, the present research focused on the seed germination of the two species. Fruits of different ripeness of both species were collected (fresh and dry seeds within and without pericarp), after which both the germination and maturation were tested. We also tested the continued maturing of fruits on cut plants and observed the development of fruits on whole plants with a cut taproot (in addition to when only the upper part of the stem with fruit racemes was cut off). In general, the seeds germinated from all stages of fruit ripeness, although the germination of dry seeds was better compared to fresh seeds. P. americana’s seeds germinated better and the fruit ripening on cut plants was also more successful compared to P. acinosa. These results could partly explain the invasive success of P. americana. According to our results, removing all fruiting plants from the eradication site is crucial regardless of the fruit development stage.
