The aim of this work was to observe the presence of ring shake in shoots stools and standards and to evaluate the possible relationships existing between these data and those characterizing the individual stems the individual stools and the entire population from the structural and typological standpoint. From the results it emerges that of standards and of shoots are involved in the defect and only 51 of stools present shoots with ring shake. The distribution of ring shake in the stems is concentrated in the middle third of the radius and as much as 50 of the defect appears in correspondence with the growth rings for the years 1971 1972 and 1973. The distribution of stools with shoots affected by ring shake is not uniform over the plot. chestnut I coppice ring shake I structure Resume Roulure et caractéristiques structurelies d un peuplement de taillis de Chataignier dans le nord du Piémont nord-ouest de I ltalie .
