| Popis | In their recent article in Alpine Botany (133:63-67, 2023a), Korner et al. revisit the outcome of an interesting experiment from 2009 (Lenz et al., Plant Ecolog Divers 6:365-375, 2013). Although I appreciate the new focus on cell wall lignification, I disagree with their main conclusion. Rather than questioning the role cold temperatures play in cell wall lignification, the authors provide experimental evidence for a thermal threshold under which the secondary cell walls of mountain pines (Pinus uncinata) at the upper treeline in the Swiss Alps exhibit a reduced lignin content. |
