The aim of this experiment is to assess cuttings that constitute the basic elements in the installation of a bioengineering structure. The main objective of this experiment is therefore to evaluate the potential for vegetative propagation of the targeted tree, shrub and herbaceous species according to simple and inexpensive experimental methods that are close to "site conditions" and therefore reproducible on a large scale on bioengineering worksites.
The cuttings are planted in one cubic meter containers, positioned in the field with watering to maintain an adequate moisture level at all times. The substrate used is an earth/sand mixture that is quite similar to watercourse soils. Fifteen cuttings per species will be monitored. Some "aerial" characteristics will be measured during the experiment (growth, number of branches, etc.), and the cuttings will be excavated in order to take different measurements on the root system after 6 months in the ground.
