Three techniques of grafting were tested at the kola, in order to retain to it (them) more efficacious for the production of vegetable material in sufficient quantity. They are the graftings in side and final slit, and that in escutcheon. These grafts were preserved in two environments at the contrasted characteristics: talon and tunnel to evaluate the effects of them. The analyses of the data revealed that mortalities are more significant during the first two weeks but, tend to be stabilized during the third. The graft in final slit, preserved under tunnel, showed a superiority expressed through the weakest death rate after three weeks compared to the shield-grafts which resisted less under the same conditions. Conversely, the shield-grafts behaved better under greenhouse than the grafts in slit. These grafts in slit final and maintained under tunnel, were revealed best adapted to the multiplication of the kola. The results of this study suggest possibilities of production of vegetable material in mass according to tested techniques.

Three techniques of grafting were tested at the kola, in order to retain to it (them) more efficacious for the production of vegetable material in sufficient quantity. They are the graftings in side and final slit, and that in escutcheon. These grafts were preserved in two environments at the contrasted characteristics: talon and tunnel to evaluate the effects of them. The analyses of the data revealed that mortalities are more significant during the first two weeks but, tend to be stabilized during the third. The graft in final slit, preserved under tunnel, showed a superiority expressed through the weakest death rate after three weeks compared to the shield-grafts which resisted less under the same conditions. Conversely, the shield-grafts behaved better under greenhouse than the grafts in slit. These grafts in slit final and maintained under tunnel, were revealed best adapted to the multiplication of the kola.

Abstract: (french)
Trois techniques de greffage ont été expérimentées chez le colatier, en vue de retenir la (les) plus efficace(s) pour la production de matériel végétal en quantité suffisante. Il s’agit des greffages en fente latérale et terminale, et celui en écusson. Ces greffes ont été conservées dans deux environnements aux caractéristiques contrastées : serre et tunnel pour en évaluer les effets. Les analyses des données ont révélé que les mortalités sont plus importantes au cours des deux premières semaines mais, tendent à se stabiliser au cours de la troisième. Les greffes en fente terminale, conservées sous tunnel, ont montré une supériorité exprimée à travers le plus faible taux de mortalité après trois semaines comparativement aux greffes en écusson qui ont moins résisté dans les mêmes conditions. A l’inverse, les greffes en écusson se sont mieux comportées sous serre que les greffes en fente. Les greffes en fente terminale et entretenues sous tunnel, ont été révélées les mieux adaptées à la multiplication du colatier. Les résultats de cette étude suggèrent des possibilités de production de matériel végétal en masse selon les techniques éprouvées.
