In dry tropical forests, herbaceous species may have dormancy mechanisms and form persistent and transient seed banks in the soil. Evolutionarily acquired, these mechanisms are efficient for the establishment and survival of these herbs, especially in forests with unpredictable climates, such as the Caatinga. Thus, our objective was to verify whether the studied herbaceous species adopt the physical dormancy mechanism and how these natural barriers are overcome, to understand the temporal dynamics existing in the soil seed bank from a Brazilian dry tropical forest.

巴西干旱森林土壤种子库中休眠和非休眠草本物种出现的动力学

在干燥的热带森林中，草本物种可能具有休眠机制，并在土壤中形成持久和短暂的种子库。通过进化获得，这些机制对于这些草药的建立和生存非常有效，特别是在气候难以预测的森林中，例如Caatinga。因此，我们的目的是验证所研究的草本物种是否采用了物理休眠机制以及如何克服这些自然障碍，以了解巴西干燥热带森林土壤种子库中存在的时间动态。
