I have read the paper of Lang et al. (8) with great interest. The authors propose a new terminology and classification of dormancy based on three main terms: eco–, para–, and endodormancy. I agree with the authors that the present nomenclature, which developed over time, is complex, confusing, and difficult to understand. A wide variety of terms have been used, often even for the same phenomenon, and some terms have several definitions. Lang and coworkers hope to bring clarity to this situation by introducing the terms eco–, para–, and endodormancy. However, I find it difficult to adapt this terminology to a physiological description of dormancy. In my opinion, the new terms Lang et al. contribute to confusion rather than to clarity.
