Rhythm of linear growth of annual shoots of almond willow

Afonin A.

The aim of the study was to identify patterns in the dynamics of daily linear growth of annual shoots of almond willow. For the analysis of seasonal dynamics of growth of annual shoots used genetically aligned material cultivated in homogeneous conditions. The empirical data obtained are approximated using the harmonic analysis methodology. It is established that the main contribution to the seasonal dynamics of the daily linear growth of shoots is made by the first harmonics with high amplitude.
