Effects of Temperature Peaks and Water Stress on Tropical Seed Germination: Experimental Trials With Species From Brazil's Northeastern Coastal Zone

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Understanding the effects of high temperatures and water deficit on germination provides valuable insights into seed stress tolerance, guiding the use of native seeds in ecological restoration. This study aimed to evaluate the effects of (1) temperature peaks and (2) water stress treatments and post‐stress recovery on the germination of some ...
