摘要: La graine est l’organe principal de propagation du papayer ( Carica  papaya ), chez qui les problemes germination sont recurrents. L’influence mode pollinisation et la conservation des papayes sur qualite leurs semences etudiee. Six cents fleurs hermaphrodites, lignee Solo n°8, marquees au stade ultime bouton floral ; une moitie ensachee pour permettre l’autofecondation l’autre, libre, laissee sans protection. Chaque semaine apres l’ultime (SAUSBF), 10 fruits obtenus chaque recoltes en extraire semences. Les graines certains extraites recolte d’autres jours conservation. Ces observees, pesees puis soumises a tests germination. premieres consistantes notees dans le fruit SAUSBF celles capables germer y sont  signalees partir 14 SAUSBF. L’âge fortement influence performances Independamment pollinisation, maximale enregistree avec d’au moins 19 avance 13 offert taux maximum aux 16 Mots cles : Qualite semenciere, (Carica L.), âge fruit, post-recolte, capacite germinative, pollinisation. GERMINATION OF PAPAYA SEED IN RELATION WITH THE AGE AND STORAGE FRUIT Papaya is mostly propagated by seed, which highly fluctuates in quality. The effect of the pollination and that post-harvest storage on seed quality was investigated. 600 hermaphrodite flowers n°8 line were tagged just before their opening half protected to insure selfpollination. Ten weekly harvested from each group collect seeds at harvest or after storage. weight capacities evaluated from  successive age fruit. Results showed no strong seedy structures arose weeks first capable germinate appeared weeks. had viability seeds. Irrespective mode, rate started with softening during significantly  enhanced behavior younger fruits, leading as sixteen. Key words Seed quality, Carica papaya, age, storage, rate, pollination.
