Natural regeneration of Prunus avium in northwestern Tunisia: influence of topographic and edaphic factors
The wild cherry (Prunus avium) is a species very appreciated in cabinet making or as transplant for the cherry tree in the Tunisian northwest carries. Prunus avium is endangered due to the excessive use of the local population. It thus seemed necessary to study the process of the natural regeneration of sowing of this species. The obtained results show that the rate of the highest sowing is observed in small places at average heights (400-600 m), in low slope, exposed northward and the muddy grounds. This study allowed us to conclude the importance of the role played by the parameters of the medium and the other climatic factors as the minimal and maximal temperature in the natural regeneration of this species at the level of our zone of study. To be able to keep and emphasize wild cherries Tunisian, we recommend using other techniques of multiplication as the taking of cuttings of segments of roots.
Key words: Wild cherry, Tunisia, parameters of the medium, multiplication by sowing.
