Seed-level disease detection in soybeans presents significant challenges, including small-sample limitations, spectral interference, and dense occlusions, which are less pronounced in leaf-level analysis. To overcome these obstacles, we propose YOLOv8-ECCI, an enhanced algorithm based on YOLOv8 for high-precision identification of purple spot disease directly on soybean seeds. Experimental results demonstrate that YOLOv8-ECCI substantially outperforms the baseline YOLOv8n model, achieving significant gains of +5.

The co-occurrence of elevated tropospheric ozone concentrations and drought in agricultural regions is anticipated to increase with climate change. Both stressors negatively impact leaf photosynthetic capacity and stomatal conductance, contributing to reductions in biomass and yield. The interaction of ozone and drought stress is complex and under-researched, particularly in field settings.

Advanced methods are necessary to improve the detection of flavescence dorée (FD), i.e., one of the most relevant grapevine (Vitis vinifera) diseases in Europe, caused by flavescence dorée phytoplasma (FDp), which is commonly carried out visually by agronomists/winegrowers, so being time-consuming and error prone.

Background: Volatile isoprenoids (VIs), such as isoprene, monoterpenes, and sesquiterpenes, participate in various forest-atmosphere processes ranging from plant cell regulation to atmospheric particle formation. The Amazon Forest is the greatest and most diverse source of VI emissions, but the lack of leaf-level studies and the logistical challenges of measuring in such remote and highly biodiverse sites bring high levels of uncertainty to modeled emission estimates. Studies indicate that leaf spectroscopy is an effective tool for estimating leaf morphological, physiological, and chemical traits, being a promising tool for more easily assessing VI emissions from vegetation.

Photosynthetic induction is the leaf-level process by which a plant assimilates CO from the atmosphere once exposed to a change in light intensity after a period of darkness or shade. In the field, photosynthetic induction can take place hundreds of times in a single day in response to rapid fluctuations in the light environment due to cloud cover, wind, solar angle, and neighbourly shading. In general, the speed of photosynthetic induction is broadly regulated by two main components: the diffusional limitations of CO reaching the sites of carboxylation; and the biochemical limitations associated with the assimilation of CO.
