Major improvements are the increase in rooting rates and the description for the first time of a successful continuous multiplication procedure. For bud induction isolated cotyledons were cultured on 1 2 LP with pM BA during 4 days. Shoot development was obtained by transfer to 1 2 LP hormone-free medium with activated charcoal. Since an additional 20 weeks were required for shoot elongation and rooting at least 70 plantlets can be expected per seed after 29 weeks based on a 70 success rate. Besides shoots can be micropropagated successively by subculturing on 1 2 LPC. conifers micropropagation organogenesis rooting tissue culture Résumé - Amelioration du protocole de multiplication par micropropagation du pin pignon Pinus pinea L. . Nous avons développé un protocole de multiplication par micropropagation de Pinus pinea L. à partir de cotylédons isolés. Les principaux progrès réalisés concernent l augmentation du taux d enracinement et la description pour la première fois d une méthode de multiplication en continu. Pour l induction des bourgeons des cotylédons isolés ont été cultivés dans le .
