Abstract

In the Monferrato (Alessandria) hazelnut cultivation area, in the first half of February 2012 a strong drop of temperature occurred. The effect of these very low temperatures was a bark vertical cracking on the single trunk of hazelnut trees and it was investigated in three (A, B and C) different hazelnut orchards. The absolute minimum temperature recorded was -22,40°C in two orchards and -16,40°C in another one. The damages intensity was estimated considering the cracks length and the width. So we obtained a damages score as follow: none, low, medium, severe and very severe. The general average of damaged trees vary from the minimum of 40,56 for orchard C, till a maximum of 69,57% for orchard B. This data seems to be related to the minimum absolute temperature values reached in each of the three considered orchards. The effects of absolute minimum temperatures, soil conditions, proximity to a stream and altitude of the plot of land were considered.
