Key Message
In a provenance trial conducted in Serbia, the provenance of the beech trees exhibited a stronger influence on leaf morphology than on survival rate.
Abstract
Provenance trials are crucial for understanding the genetic diversity within beech provenances and advising forestry management practices. In this study, by integrating leaf morphometric analyses and survival data from a 16-year-old provenance trial in Serbia, we aimed to uncover patterns and mechanisms that govern plant–environment interactions in beech (Fagus sylvatica L.) ecosystems. The provenance trial used in this study was established in 2007, as part of the broader European network, from seedlings of 22 provenances originating across Europe. In the fall of 2007 and 2010, and in the summer 2023, plant vitality was recorded within each provenance. For geometric morphometrics, leaves were collected in 2023. The analyses tested the effects of provenance, provenance geographical origin, and provenance survival trend on leaf size and shape. The results showed significant variation in leaf size and shape and revealed that while there was no clear pattern of correlation between survival percentage and leaf morphology, provenance origin did show significant influence on leaf size and shape. Additionally, source stands environmental factors exerted a stronger influence on leaf shape than on leaf size variation. The observed variability in beech leaf morphology on one side, and survival rates on the other side, serve as indicators of the species' resilience and ability to adjust to changing environmental conditions.
