Vegetative propagation by aerial layering of pterocarpuserinaceus: in the sudanian zone
Researches on the development of vegetative propagation techniques have been carried out on Pterocarpuserinaceus trees in Burkina Faso. The objective of the study is to develop low cost production techniques of plants by air layering. It is specifically to highlight the diameter of the branch, the positions of the layers on the branch and the frequencies of watering which optimize the rooting rate of the layers. Two trials were carried out in rainy seasons in Saria, Burkina Faso, on a 10-year-old P. erinaceus plantation, where the mean height was 10.7 ± 2.5 m.
