Pre-dawn water potential and nutritional status of pedunculate oak (Quercus robur L.) in the north-east of Slovenia

Čater, Matjaž (avtor), Simončič, Primož (avtor), Batič, Franc (avtor)

In the 1997 growth period monthly measurements of pre-dawn water potential, electrical resistance of the cambial zone, groundwater level and quality together with annual dynamics of macronutrive elements in leaves and heavy metals (Zn, Pb, Cd) were performed. Two plots having different groundwater tables and crown defoliation were studied in the pedunculate oak forest complex (Querco Roboris-Carpinetum M. Wraber) in the north-east of Slovenia. Results showed lower (more negative) values of pre-dawn water potential and higher values of cambial electrical resistance on the plot with greater crown defoliation, which also had a lower groundwater table. Groundwater seems to be the key factor in the process of oak decline.
