dc.descriptionGlobal warming significantly impacts the environment, directly affecting plant development. Neoglaziovia variegata (Arruda) Mez is a Bromeliaceae endemic to the Caatinga, has highly resistant fibers used for income generation and has landscaping and medicinal potential. The study aimed to identify the thermal and saline thresholds that influence the germination of this species. In different experiments, the seeds were placed to germinate at constant temperatures between 15 and 40 °C and in substrate soaked in NaCl solution from 0 to 14 dS.m-1. The combination of thermal and salt stresses and the recovery of seeds after stress were also evaluated. All experiments followed a completely randomized design, with four replications of 25 seeds and lasted 28 days. The data were analyzed by thermal time and halotime models, establishing the thresholds for germination. The minimum and maximum temperatures for germination were 14.3 and 41.7 °C, respectively, with the ideal temperature of 31.1 °C. The germination threshold in saline medium was 16.2 dS.m-1. The seeds showed viability after being removed from the stress condition. The wide temperature range and high saline threshold show that the species can survive the most pessimistic climate change scenarios
