Summary
Seed germination responses to temperature and light vary significantly among six dry-forest woody Fabaceae species, offering critical insights for ecological restoration and climate change adaptation. The study found that mechanical scarification substantially increases germination rates, while higher temperatures generally accelerate germination in dark conditions, though responses in germination synchrony differ among species. These findings highlight the importance of understanding not just germination percentage and time but also synchrony to guide effective management actions. The research involved a multifactorial experiment with five temperature ranges (10–40 °C), two light regimes, and scarification conditions for species such as Mimosa luisana and Vachellia constricta, which are ecologically, culturally, or economically significant in the Tehuacán-Cuicatlán Valley, Mexico. The study underscores potential threats to natural recruitment due to warmer, drier conditions and deforestation, emphasizing the need for targeted restoration strategies.
