“…There are non-destructive sampling methods using remote sensing spectroscopy for measuring plant biomass, and these methods are mainly used in the macro or large-scale research [ 41 , 42 , 43 , 44 , 45 , 46 ]. In order to directly reflect the characteristics of biomass, combined with the sampling methods commonly used by previous researchers [ 47 , 48 , 49 , 50 , 51 , 52 ], we chose the harvesting method to measure the biomass. That is, the aboveground parts of P. australis in five habitats were mowed in a 0.5 m × 0.5 m square and then dried in an oven at 75 °C for 48 h. The final weight was recorded when the weight showed no further reductions.…”

Water shortages have an important impact on the photosynthetic capacity of Phragmites australis. However, this impact has not been adequately studied from the perspective of photosynthesis. An in-depth study of the photosynthetic process can help in better understanding the impact of water shortages on the photosynthetic capacity of P. australis, especially on the microscale. The aim of this study is to explore the photosynthetic adaptation strategies to environmental changes in saline‒alkaline wetlands. The light response curves and CO2 response curves of P. australis in five habitats (hygrophilous, xerophytic, psammophytic, abandoned farmland, paddy field drainage) in saline‒alkaline wetlands were measured at different stages of their life history, and we used a nonrectangular hyperbolic model to fit the data. It was concluded that P. australis utilized coping strategies that differed between the growing and breeding seasons. P. australis in abandoned farmland during the growing season had the highest apparent quantum efficiency (AQE) and photosynthetic utilization efficiency for weak light because of the dark environment. The dark respiration rate of P. australis in the drainage area of paddy fields was the lowest, and it had the highest values for photorespiration rate, maximum photosynthetic rate (Pmax), photosynthetic capacity (Pa), biomass, maximum carboxylation rate (Vcmax), and maximum electron transfer rate (Jmax). The light insensitivity of P. australis increased with the transition from growing to breeding season, and the dark respiration rate also showed a downward trend. Moreover, Vcmax and Jmax would decline when Pmax and Pa showed a declining trend, and vice versa. In other words, Vcmax and Jmax could explain changes in the photosynthetic capacity to some extent. These findings contribute to providing insights that Vcmax and Jmax can directly reflect the variation in photosynthetic capacity of P. australis under water shortages in saline‒alkaline wetlands and in other parts of world where there are problems with similarly harmful environmental conditions.

“…Encontraron que a pesar de que la tasa de descomposición de las macrófitas era pequeña, estas resultaban co-sustrato apropiado para proceso de compostaje ya implementados. Asimismo, el compost producido mejoro significativamente las condiciones del suelo estudiado, mejorando el crecimiento de plantas sin generar elevada acumulación de material toxico [13].…”

Las actividades antropogénicas han afectado recursos naturales limitados, como el recurso suelo, el cual soporta diferentes actividades que se pueden considerar indispensables para la humanidad. En este sentido, la salud del suelo es ampliamente estudiada desde lo académico, especialmente en el contexto de la recuperación de suelos degradados. Así, el presente documento desarrollo una vigilancia tecnológica que permitirá analizar la información disponible relacionada a técnicas de recuperación de suelos degradados, lo que permite presentar un contexto general, las técnicas y estudios más significativos del área. La vigilancia se realizó empleando las bases de datos de Scopus y ESPACENET, que corresponden a la búsqueda de artículos científicos y patentes, respectivamente. Se evaluaron indicadores relacionados al número de publicaciones, tipo de publicación, registro de patentes por país, entre otros. Se encontraron más de 22.907 artículos y 380 patentes que correspondían al objeto de la búsqueda. Estas investigaciones e invenciones se relacionan, en su mayoría, a procesos de fitorremediación enfocados en la problemática de contaminación de suelos por metales pesados, y se desarrollan en países como China y Estados Unidos, lo que se asocia al crecimiento de procesos agroindustriales altamente tecnificados, la mitigación de la degradación por contaminación antrópica y la búsqueda del desarrollo sostenible.

Environmental pollution caused by urbanization, agricultural intensification, and industrialization has led to an increase in the disposal of toxic effluents in aquatic environments. Most ecosystems in the world receive a variety of toxic metals (TMs) that exceed the capacity of water bodies to absorb or recycle them, thereby threatening aquatic and human life. Physicochemical remediation methods encounter problems because of the high cost, labor input, and use of chemicals with long residence times that later add toxic by‐products. However, bioremediation techniques are a safe option for mitigating environmental pollution because of their high efficiency, cost‐effectiveness, non‐intrusiveness, eco‐friendliness, ease of application, and social acceptance. Submerged and free‐floating macrophytes were found to be more effective in the bioaccumulation of TMs than emergent macrophytes. Furthermore, most studies have suggested the use of macrophytes for the removal of TMs from water bodies; however, studies on the management of phytoremediated biomass are scarce. This review demonstrates the role of various macrophytes for the removal of TMs from water bodies and suggests techniques for the disposal and recycling of phytoremediated biomass with accumulated TMs. Further, the applications of genetically modified plants, nanotechnology, and native hyperaccumulators have been suggested as suitable candidates for greater efficiency of phytoremediation and appropriate management of TMs in the environment in the future.
