The impact of exogenously applied glycine betaine (GB; 0, 5, 10, 20 and 50 mmol) was evaluated in preventing Vigna radiata from the adverse effects of salt (100 mmol NaCl) stress. Salinity reduced growth parameters, such as plant height and fresh and dry weight of plants, while GB application significantly alleviated the decline. Salinity stress led to a decline in total chlorophylls and carotenoids, as well as a reduction in the net photosynthetic rate and gas exchange attributes, including stomatal conductance, transpiration rate, and intercellular CO2. However, GB supplementation significantly alleviated this decline. Salinity...

Soil salinisation is a key determinant in soil fertility decline, exerting a direct negative impact on soil organic carbon. In the context of global warming, investigating the response mechanisms of soil organic carbon pools with varying salinity levels to climate change is essential for accurately assessing the carbon cycle and emission potential of degraded soils. Based on soil samples (B1–B6) collected along a coastal salinity gradient, indoor incubation experiments were conducted at 15 °C and 25 °C to characterise soil respiration and its temperature sensitivity (Q10). Double-exponential models were used to simulate soil organic carbon (SOC)...

The research was conducted in a long-term stationary experiment established on light grey forest surface-gleyed soil in 1965. Data presented in this study were collected during 2022–2024 growing seasons within the framework of this long-term experiment. The experiment is registered in the NAAS long-term field experiments registry (certificate No. 29) and the Global Long-Term Agricultural Experiments Network (GLTEN). The study examined the effect of growing red clover in a four-field crop rotation on nutrient balance at different fertiliser and lime doses and ratios. Red clover was used for feed and feed-green manure purposes. The research aimed...

Developing and employing new, sustainable, and eco-friendly biostimulants that enhance plant growth and alleviate the harmful effects of environmental challenges is a major focus for many researchers. Salt stress is a critical constraint on plant growth and a limiting factor in crop productivity, particularly during the early developmental stages in the nurseries. Syzygium cumini (L.) Skeels (Java plum) is an important fruit tree and widely cultivated in gardens as an ornamental plant. This study was designed to develop Cassia javanica subsp. nodosa leaf extract (CLE) as a new sustainable and eco-friendly biostimulant capable of...
Decoupling of stomatal and mesophyll recovery drives photosynthetic resilience to water deficit in sugar beet: evidence from multiscale structural and functional traitsOriginal Paper

Water deficit severely constrains sugar beet productivity by impairing photosynthetic capacity. However, the underlying structure-function mechanisms conferring photosynthetic resilience remain poorly characterised. This study investigates the temporal dynamics of photosynthetic limitations and structural adaptations in sugar beet during water deficit and subsequent rehydration. We found that water deficit significantly reduced the maximum net CO2 assimilation rate (ANmax) and the Rubisco carboxylation rate (Vcmax) by impairing CO2 diffusion and biochemical processes. The reduction in photosynthetic capacity...

Drought is a major abiotic stressor that limits crop growth and is often associated with oxidative stress. We evaluated whether foliar silicon (Si) application affects primary root anatomy, plant height, and phenolic metabolism in three common buckwheat (Fagopyrum esculentum) cultivars (La Harpe, Panda, and Smuga) exposed to water deficit. Plants were grown under controlled conditions in four treatments: control; drought; control + Si, and drought + Si. Qualitative anatomical assessment revealed that Si promoted more advanced development of the primary root central cylinder, most notably in La Harpe under drought conditions, where a continuous...
