Abstract

The epicormic potential was represented by the number of visible epicormicbuds (primary and secondary) present at a given time and on a given lengthof stem. Data were collected from sixty-six 4-year-old annual shoots on 17-year-old Quercus petraea with 3 stand densities. We estimated the epicormic potential in 1997 and then followed its evolution over the next 2 years. Preliminary results showed that the epicormic potential decreased from 1997to 1999, independently to the stand density. The loss of epicormic buds (death or development into shoots) was not compensated by the production of new epicormic buds. Furthermore, we report that the composition of the epicormic potential was unchanged for these 2 years: one third were primary epicormic buds and two thirds were secondary epicormic buds. Secondary epicormic buds were mainly found as individual and located at the base of branches. No formations of large clusters of epicormic buds were observed.
