Odvisnost velikosti prevodnih elementov doba (Quercus robur L.) od temperatur na dveh rastiščih Querco-Carpinetum v Sloveniji

The aim of our study is to fully investigate the relationship between mean monthly temperatures and vessel features. Two vital and one declining groups of pedunculate oak from two Querco-Carpinetum sites in Slovenia are analyzed. Chronologies of mean vessel area and sum of vessel area were...
