Effect of the sites on the phenology of Prunus avium in Tunisia
Keywords:
Prunus avium, Northwest of Tunisia, Sites, PhenologyAbstract
The phenology of wild cherry in the Northwest of Tunisia was studied over the year 2013. The phenological events reserved are the
leafing, the flowering and the fruiting. The observation of the various phenological phases of this species (bud burst, blossoming or
fruiting) reveals a variation inter-site and intra-site. The precocity reveals for the sites of Tabarka (Hamdia and Kroufa) can give some
explanation of differences of edaphic and topographic characteristics. The analyses of variances show that the duration of the various phenological phases of the wild cherry is significantly connected with the geographical localization of sites. The differences observed within the same site can give some explanation by the genetic variability of trees. These results open perspectives for the valuation and the genetic preservation of this commercial species in the northeast of Tunisia.
