Summary: Chlorophyll fluorescence can be used as a proxy for photosynthesis in boreal forests. This study measured the spectral chlorophyll fluorescence in leaves of three dominant evergreen species in the boreal ecosystem and analyzed the correlations with other traits to understand the spatial and temporal variation in chlorophyll fluorescence. The findings suggest that the diversity of species and light environments within an ecosystem generate baseline variation in leaf spectral chlorophyll fluorescence and contrasting seasonal photosynthetic acclimation patterns.

Summary: Accurate estimation of canopy chlorophyll content (CCC) is crucial for quantitative remote sensing. This study focused on maize and found non-uniform vertical distribution of leaf chlorophyll content (LCC), which affects CCC monitoring accuracy. The study analyzed LCC profiles, leaf reflectance spectra, and their correlations, finding that leaf reflectance can be used to estimate CCC directly.

Summary: In urban areas, the selection and integration of suitable ornamental plants is crucial due to constraints like building shading. Proper distribution of trees, shrubs, and herbaceous plants based on light requirements and shading intensity is important. Shadow projection and physiological parameters such as light compensation point help determine the positioning of ornamental species. Non-destructive leaf gas exchange, chlorophyll a fluorescence, and chlorophyll content can be useful tools in selecting suitable ornamental plants under diverse shading conditions.

Summary: The quality and intensity of light have a significant impact on the photosynthetic efficiency of plants. This research investigated the effects of different light spectral compositions on the photosynthetic efficiency of three cultivars of Begonia rex. The results showed that the combination of 15%B85%R and control conditions had the highest quantum yield and Fv/Fo values for 'Black Velvet' plants.

Summary: This study found that under high temperature conditions, the emission of leaf monoterpenes significantly increased in the INRA809 grape variety, while there was no significant change in the SMA130 variety. Additionally, when leaf temperature exceeded 30 degrees Celsius, INRA809 maintained higher photosynthetic rates and stomatal conductance values. This suggests that monoterpenes emission plays a significant role in heat tolerance of grapes under high temperatures.

Summary: The aim of this experiment was to study the response of Platycerium bifurcatum's photosynthesis to a 6-week water deficit. The results showed that after a decrease in leaf hydration by 10-15%, disturbances in the photosynthetic process occurred, especially in the initial photochemical reactions, leading to a rapid decrease in plant vitality and significant fluctuations in chlorophyll a fluorescence parameters. The relative size of PSI antenna structures compared to PSII also decreased in the following weeks of water deficit. Changes in the functioning of photosynthesis light phase and the pigment composition of leaves were related to the resistance of elkhorn fern to long-term water deficit.

Summary: The study found that leaf nitrogen content significantly influenced the response of PSI to fluctuating light in tomatoes grown under nitrogen deficiency. High-nitrogen plants were more susceptible to over-reduction of PSI compared to low-nitrogen plants, which gradually increased PSII electron flow to avoid this issue.

Summary: The study found that the use of fluorescence-based sensors can reliably assess chlorophyll and nitrogen content at leaf and canopy levels, providing absolute and relative sufficiency threshold values under standard nursery conditions. By determining optimal shoot nitrogen concentrations and corresponding non-destructive nitrogen balance index values, they can be used to make decisions on nitrogen application and monitoring of the considered species.

Summary: Knowledge of plant photosynthesis, biomass, and stress resistance is important for understanding vegetation growth and restoration. However, the response of these plant traits to plant-soil interactions at different successional stages is still poorly understood. A greenhouse experiment was conducted to investigate the effects of soil from different successional stages on plant traits, and the results showed specific directional responses of plant traits to plant-soil interactions.

Summary: This study investigated the adsorption process and mechanism of heavy metal ion lead using a magnetic ash/graphene oxide nanocomposite through artificial intelligence simulation and molecular dynamics calculations. The adsorption was found to occur through electrostatic interactions and van der Waals bonding, with the lead-water-GO configuration showing the highest adsorption affinity. An artificial neural network model was developed to predict the adsorption capacity, and the initial ion concentration was found to have a significant effect on the equilibrium concentration.
