Abstract

Hormone application has been more of individual application. To ascertain the best application technique,
Synsepalum dulcificum cuttings were used for this study. The experiment was a 2 x 5 factorial treatment laid out in
a completely randomized design. Two quick-dip methods (cluster and individual) as one factor, and Indole-3-
butyric acid (IBA 200 mg/l and 250 mg/l), and Naphthalene acetic acid (NAA 200 mg/l and 250mg/l) as the other
factor. Distilled water was used as control, and cuttings assessed two months after planting. Data collected were
statistically analysed using two factor ANOVA procedure. Treatment means were separated using Least
Significant Difference procedure at 5% probability level. Results show that 1BA 200mg/l had a better effect on
number of roots per cutting (2.38), and roots length (4.4), followed by NAA 200mg/l (number of roots per cutting
as 2.75, while roots length was 1.42cm). Although NAA 200mg/l cuttings had a higher number of roots, but IBA
200mg/l treated cuttings will perform better considering their root lengths. Also, clustered treated cuttings
recorded appreciable increase in number of roots, new leaves and roots length than individual treated cuttings.
Cluster treatment is thus, recommended for the much needed vegetative propagation of S. dulcificum and
probably for other species.
