Key message
The application of PKPF mitigates stress from excess solar radiation in the species studied during the planting phase by reducing photochemical damage and increasing photosynthetic assimilation.
Abstract
Global warming represents a significant threat to biodiversity, with rising global temperatures severely impacting ecosystems, including forests. The Atlantic Forest, one of the most diverse and threatened biomes in the world, faces critical challenges in restoring its degraded areas, especially due to high solar radiation that compromises the initial establishment of seedlings. This study explores the use of processed-kaolin particle film (PKPF) technology as a solution to mitigate the harmful effects of excessive solar radiation, promoting seedling development and offering an innovative and promising strategy for Atlantic Forest restoration. PKPF was applied to the leaf surfaces of two native species, Cordia superba and Citharexylum myrianthum, during the intense summer of 2022. Through eco-physiological and anatomical assessments, the study found that PKPF significantly improved plant performance by increasing photosynthetic efficiency and net CO₂ assimilation, reducing stress during radiation peaks, and preserving the mesophyll structure via a protective layer that reflects excess solar radiation. These results highlight PKPF as a viable and innovative tool to support the restoration of Atlantic Forest ecosystems amid increasing pressures from climate change, making it a crucial step to address the early stage challenges of environmental restoration projects.
