La domestication de Lippia multiflora, plantes aux multiples vertus en pharmacopee et medecine est un enjeu de taille en Cote d’Ivoire. Cependant, l’insuffisance de semences, due au faible taux de germination des graines, limite l’extension de sa culture. La presente etude avait pour objectif l’extraction, la purification et la caracterisation morpho-physiologique des graines de Lippia multiflora Moldenke (Verbenaceae). Il s’agissait plus specifiquement de determiner la purete specifique, le nombre de graines par unite de masse, le diametre moyen et le taux d’humidite ; le taux de germination des graines de L. multiflora. Aussi, il s’est agi d’etudier l’impact du milieu sur le pouvoir germinatif des graines et de faire un suivi post-germination des plants en milieu reel. Apres extraction des graines, des mesures physiques et des tests de germination ont permis de determiner les caracteristiques morpho-physiologiques de celles-ci. L’etude a montre que le lot de graine etudie a une purete specifique de 70%, les graines ont un diametre moyen de 0,34± 0.1 mm, une teneur en eau de 14±5.4 % et un taux de germination de 42,25%. Les tests de germination apres un sejour prolonge dans divers milieux, revelent qu’un milieu refrigere (7° C) confere une plus longue viabilite aux graines. Le suivi post-germination au champ montre une evolution reguliere de la hauteur des plants, passant en moyenne de 2,58 cm a 8,8 cm au bout de 3 mois. Sur la meme periode, le nombre moyen de feuille varie de 4,03 a 21.Mots cles : Lippia multiflora, graine, caracterisation, germination, suivi post-germination.   English Title: Morpho-physiological qualities and evaluation of the germination behavior of seeds of the savannah tea tree (Lippia multiflora Moldenke)The domestication of Lippia multiflora, plants with multiple virtues in pharmacopoeia and medicine is a major challenge in Cote d'Ivoire. However, the lack of seed, due to the low germination rate, limits the extension of its cultivation. The purpose of this study was the extraction, purification and morpho-physiological characterization of the seeds of Lippia multiflora Moldenke (Verbenaceae). More specifically, it involved determining the specific purity, the number of seeds per unit mass, the average diameter and the humidity rate; the germination rate of L. multiflora seeds. Also, it was a question of studying the impact of the environment on the germination power of seeds and of making a post-germination follow-up of the plants in real environment. After the seeds extraction, physical measurements and germination tests were carried out to determine the morpho-physiological characteristics. Results showed that the seed lot studied has a specific purity of 70%, an average diameter of 0.34 0.1 mm, a water content of 14 5.4% and a germination rate of 42.25%. Germination tests after a prolonged stay in various environments reveal that a refrigerated area (7 °C) confers a longer viability to the seeds. Post-germination monitoring in the field shows a steady increase in plant height from an average of 2.58 cm to 8.8 cm after 3 months. Over the same period, the average number of sheets varies from 4.03 to 21.Keywords: Lippia multiflora, seed, characterization, germination, post-germination monitoring.
