Rapid field multiplication of plantains using benzyl adenine or coconut water-treated split corms

J K Osei

Abstract




An appropriate inexpensive technique for rapid field multiplication of local false and true horn plantain cultivars, Apantu and Asamienu, has been developed by injecting 6 or 8 ml boiled and filtered coconut water from fully ripe dried fruit or 4 ml 10-2 M benzyl adenine on 3 consecutive alternate days at the base of over 35 cm tall split corm-derived suckers, and sprouting the split corms of the treated suckers in moist sawdust, 3 weeks after the injection treatments. Up to 1,000 suckers can be generated from one Apantu sucker in a year, and 3,375 suckers from one Asamienu sucker in 18 months with the coconut water treatment. The cost of 25 ml coconut water required to treat one sucker is insignificant compared with the multiplication ratios derived from the treated suckers.

Une technique appropriee et moins chere pour la multiplication rapide sur Ie terrain de deux varietes locales de plantain Apantu (une corne fausse) et Asamienu (une come veritable) a ete obtenue par injection de 6 ou 8 ml du jus de noix de coco mur sec apres L' ebullition et la filtration ou de 4 ml 10-2 M benzyle adenine pour trois jours. Consecutifs alternes a la base de surgeons-derives de bulbes divises d'une taille au-dessus de 35 cm, et germant les bulbes divises de surgeons traites en sciure de bois moullee, trois semaines apres les traitements d'injection. Jusqu'a 1000 surgeons pourraient etre produits d'un surgeon d' Apantu dans un an et 3,375 d'un surgeon d' Asamienu en 18 mois avec Ie traitement du jus de noix de coco. Le cout de 25 ml du jus de coco exige pour traiter un surgeon est insignificant compare avec les proportions de multiplication obtenues de surgeons traites.
