Abstract The use of complementary light spectra is a potential new approach to studying the increase in plant resilience under stress conditions. purpose this experiment was investigate effect different on growth and development strawberry plants salinity alkalinity Plants were grown greenhouse ambient irradiated with blue (460 nm), red (660 blue/red (1:3), white/yellow (400–700 nm) during developmental stages. treatments as follows: control (non-stress), (40 mM NaHCO 3 ), (80 NaCl). Our...

Considering the destructive effect of stresses on photosynthetic apparatus plants and important role light in photosynthesis, we investigated complementary under salinity alkalinity stress conditions. Light-emitting diodes (LEDs) monochromatic blue (460 nm), red (660 dichromatic blue/red (1:3), white/yellow (400-700 nm) at 200 μmol m-2 S-1, without LED treatment were used. The treatments three stages: Control (no stress), Alkalinity (40 mM NaHCO3), Salinity (80 NaCl). Our results showed that...

Limited water resources and natural drought may result in reduced availability for the population’s needs maintenance of proper vegetation condition. Understanding impact on turfgrass species is essential to developing strategies that enhance adaptability plants stress. It vital maintaining green areas cities under changing climatic conditions. Therefore, studies ability turfgrasses recover after periods without irrigation are becoming increasingly essential. We conducted research determine...

Abstract The xenic strain Chlorella sorokiniana was grown together with selected fungal strains to investigate the effect of fungi on algal photosynthetic performance during cultivation. introduction well‐selected can potentially increase cultivation efficiency. bacteria that inhabited algae were identified and coexistence in liquid solid media examined. Chlorophyll a fluorescence measurement, commonly used method for determining efficiency plant photosynthesis under stressful conditions,...

Despite covering only 2–6% of land, wetland ecosystems play an important role at the local and global scale. They provide various ecosystem services (carbon dioxide sequestration, pollution removal, water retention, climate regulation, etc.) as long they are in good condition. By definition, wetlands rich ecosystems. However, ongoing change with ambiguous balance rain a temperate zone leads to drought conditions. Such periods interfere natural processes occurring on restrain normal...

Enhancing plant productivity and mitigating the impact of environmental stressors require a thorough understanding phytomonitoring physiological features indicative health. This study delves into response cucumber plants to phosphorus deficiency employing diverse tools identify key indicators unravel underlying mechanisms. Under deficiency, rapid in older leaves was observed through analysis chlorophyll carotenoid content. Molecular-level changes photosynthetic performance were found be...

Strawberry is one of the plants sensitive to salt and alkalinity stress. Light quality affects plant growth metabolic activities. However, there no clear answer in literature on how light can improve performance photosynthetic apparatus this species under The aim work was investigate effects different spectra supplemental strawberry (cv. Camarosa) stress conditions. blue (with peak 460 nm), red 660 blue/red (1:3), white/yellow (1:1) (400-700 nm) ambient were used as control. There three...

Particulate matter (PM) is a serious air pollutant that poses significant health risks. One solution to reduce PM concentrations in these areas through phytoremediation, process involves using plants remove contaminants from the environment. In this study, we investigated capacity of spontaneous flora—herbaceous plants, shrubs, and trees growing five zones road—to absorb on their foliage. The study found differences accumulation PM, with highest recorded Zone V, which boasted blend three...

The response of some photosynthetic parameters (CO2 assimilation, transpiration rate, stomatal conductance, intercellular CO2 concentration, water-use efficiency, and chlorophyll content), shoot development, the morphological features root system to differentiated conditions nitrogen supply was tested in festulolium (Festulolium braunii K.
