Dynamics of branch population in the canopy of young scots pine stands

Life tables were developed for the branch population in the canopy of young Scots pine ( Pinus sylvestris L.) stands. The death of branches began when a branch cohort was 5–6 years old. Even in widely spaced stands, no branches older than 14 years were found. All the dead branches were pruned off wh...

Description
Summary:Life tables were developed for the branch population in the canopy of young Scots pine ( Pinus sylvestris L.) stands. The death of branches began when a branch cohort was 5–6 years old. Even in widely spaced stands, no branches older than 14 years were found. All the dead branches were pruned off when the age of a branch cohort exceeded 20 years. A model based on the per-capita rate of increase of branches and the carrying capacity of branches in a particular stand gave fairly good estimates of the cumulative number of branches in the canopy. The properties of the proposed model for the branch population are discussed.
