“…In Amazon floodplain forest species, new leaf expansion, photosynthetic activity, and wood production occur underwater during the submergence season (Waldhoff et al, 2002;da Fonseca et al, 2009). Although direct comparisons between anatomical data obtained in this study and those for Amazonia are not possible because measurements were taken from tall rates of unsubmerged saplings were lower than those of submerged saplings, but the biomass of plant parts and whole plants were higher in unsubmerged plants.…”

“…Woody plants have relatively slower growth than herbaceous species, and therefore employ the LOQS. In Amazon floodplain forests, where the river water level rises for several months per year, woody trees commonly have no shoot elongation during submergence (Parolin, 2009) but are able to maintain photosynthetic activity under water for several months (Waldhoff et al, 2002). Submergence is routine for wetland woody species growing in riparian and coastal areas, especially when plants are in the juvenile stage.…”

Aim of study: Withstanding total submergence and reaeration following submergence is essential for the survival and establishment of wetland species. We focused on “LOES–low oxygen escape syndrome” and “LOQS–low oxygen quiescence syndrome” and compared tolerances to total submergence among wetland woody species differing in morphological adaptation to soil flooding.Area of study, materials and methods: This study examined the survival of 2-year-old saplings of Taxodium distichum (LOQS species), and Alnus japonica and Metasequoia glyptostroboides, (LOES species), during and after total submergence. Saplings were completely submerged, then de-submerged to determine trends in survival and growth.Main results: The M. glyptostroboides and A. japonica saplings could not survive prolonged submergence for more than 8 weeks, whereas saplings of T. distichum survived for over 2 years. Submerged saplings of all species showed no significant growth or modifications in morphology and anatomy under water, such as shoot elongation, adventitious root formation, and/or aerenchyma development. All T. distichum saplings that were de-submerged in the second year had the same pattern of shoot growth regardless of differences in timing and seasonality of de-submergence. Wood formation in T. distichum saplings ceased during submergence and resumed after de-submergence in spring and summer, but not in autumn.Research highlights: T. distichum saplings, which survived longer submergence periods than A. japonica and M. glyptostroboides, had physiological characteristics, such as suspension of growth and metabolism, which allowed survival of protracted total submergence (at least 2 years) when saplings were immersed during the dormant stage before leaf flushing.Keywords: Alnus japonica; Metasequoia glyptostroboides; survival rates; Taxodium distichum; total submergence.Abbreviations: LOES, low oxygen escape syndrome; LOQS, low oxygen quiescence syndrome.

“…En Boltonia decurrens (Asteraceae), la inundación reduce la asimilación de CO 2 , pero no la eficiencia potencial del PSII (F v /F m ) (Pienkowski et al, 1998). En general, la inundación disminuye la eficiencia cuántica real del PSII y aumenta la disipación no fotoquímica, estos efectos incrementan al aumentar la duración del estrés (Else et al, 2009) o la intensidad lumínica (Waldhoff et al, 2002). Sin embargo, la intensidad del estrés y las demás condiciones ambientales (luz, concentración de CO 2 ) necesarias para disminuir la actividad fotosintéti-ca dependen del genotipo, por lo que es necesario hacer estudios específicos en girasol.…”

Plantulas de tomate.Foto: Álvarez-Herrera. RESUMENEl girasol es una Asteraceae con alto potencial como planta de corte. Esta planta está expuesta a una amplia fluctuación de condiciones ambientales como luz, temperatura, suministro de agua y nutrientes. Estas condiciones pueden generar estrés sobre las plantas. El girasol presenta resistencia a la sequía, bajas y altas temperaturas. Los efectos del estrés dependen de la intensidad y de la etapa fenológica en que se presente. La fluorescencia puede ser empleada como herramienta para obtener información acerca de la influencia del estrés sobre el estado fisiológico del aparato fotosintético de las plantas y su respuesta será indicadora del daño o alteración en él. El objetivo de la presente revisión es exponer resultados de investigaciones científicas sobre los diferentes tipos de estrés evaluados en Helianthus annuus y la forma como ha sido empleada la fluorescencia como un indicador de dicho estrés. Contribuyendo así a ampliar la información disponible sobre esta importante especie.
