Abstract

Nous avons réalisé une étude comparative de la production expérimentale de tubercules en utilisant comme semences des bulbilles, des tubercules entiers de même classe de poids (15-25g) et des vitroplants. Nous obtenons en moyenne 1 tubercule par plante issue de bulbille ou de tubercule comparé à 7 tubercules pour les vitroplants. Le poids moyen des tubercules se situe entre 1.4 et 1.7 kg pour les bulbilles ou les semenceaux, et est seulement de 0.2 kg pour les vitroplants. Le rendement moyen en tubercules par plante est de 1.7, 1.8 et 1.4 kg respectivement pour les bulbilles, tubercules et vitroplants. Le rendement en tubercules commercialisables (poids supérieur à 400g) est de 16.5 T pour les vitroplants, entre 32.5 et 34 T pour les bulbilles ou les semenceaux, sur la base de 20 000 plants à l'hectare. De plus, seuls les vitroplants génèrent plus de 25 000 tubercules utilisables directement comme semences (25- 100g) et plus de 20 000 tubercules (10-25g) potentiellement utilisables moyennant quelques précautions.
