Abstract
Four ligneous species from the tropical forest in the east of Madagascar with a proven or potentially high economic value were subject to ‘lowtech’ vegetative propagation tests from stem cuttings The species concerned were Aphloia theiformis Ilex mitis Prunus africana and Ravensara aromatica The cuttings were threenode segments of stems on which one leaf was retained All the species proved amenable to rooting The maximum percentage of rooting ranged from 33 for P africana to 60 for I mitis Rooting success was dependant on the season of cutting high in the hot season from October to May and null in cold season This study is the first successful attempt at propagating cuttings from Malagasy forest species This result is of particular importance to P africana threatened by destructive exploitation in Madagascar It goes a step further in the domestication of this species by demonstrating the ability of cutting from 10 year old ortets collected in natural forest to root as it offers the possibility of a reliable and effective method of reintroduction for the species in overexploited zonesThis study was conducted by the Unité de Recherche en Partenariat “Forêts et Biodiversité” a collaboration between the University of Antananarivo the FOFIFA and the CIRAD It was supported by the French Ministry of Foreign Affairs Project FSP “Forum de la Recherche à Madagascar”/Forma by European Union INCO/Foreaim Project and by INDENAMadagascar The authors would like to express their appreciation to the NGO “L’Homme et l’Environnement” for its help and hospitality in Vohimana Forest and V Rahajanirina W Ramahafaly and E Rakotoarisoa for their technical assistance
