Vegetative propagation of Ricinodendron heudelotii, a West African fruit tree
Leafy stem cuttings of Ricinodendron heudelotii (Baill) Pierre ex Pax, a West African fruit tree, were taken from seedlings or coppice shoots and inserted in a low-technology non-mist propagation system in Cameroon. Three separate experiments were tested: (i) six propagation media, namely sawdust (S...

Summary: | Leafy stem cuttings of Ricinodendron heudelotii (Baill) Pierre ex Pax, a West African fruit tree, were taken from seedlings or coppice shoots and inserted in a low-technology non-mist propagation system in Cameroon. Three separate experiments were tested: (i) six propagation media, namely sawdust (SD), fine sand (FS), medium sand (MS), gravel (G), and 50:50 mixtures of G:SD and MS:SD; (ii) four IBA concentrations, namely 0,8, 40 and 200 |Ig IBA dissolved in 10 ul of alcohol; and (iii) four leaf area treatments, namely 0, 25, 50 and 80 cm2, obtained using paper templates. The overall effect of propagation medium on final rooting percentage was highly significant (p = 0.003, ANOVA), highest values being recorded in FS and SD. The number of roots per rooted cutting also differed markedly between treatments, mean values ranging from 3.8 to 7.3 in G and SD respectively. Application of IBA had no significant effect on final
rooting percentage, although root number was positively related to IBA concentration, values ranging from 2.7 to 10.5 in 0 and 250 |ig respectively. Leaf area had a highly significant effect on rooting percentage and root number (p < 0.001, ANOVA), with highest values recorded in the 80 cm2 treatment. Defoliated cuttings completely failed to root. The maximum rooting percentages exceeding 80%
obtained in all three experiments indicate that R. heudelotii is amenable to vegetative propagation using these techniques, which should be of value to current domestication efforts. |
