Abstract

This study examined the comparative effect of potential rooting promoting substances on rooting of Vitex diversifolia semi-hardwood cuttings. Treatments were comprised of a negative (untreated) and positive (Indole-3-Butyric Acid, IBA) control, aloe vera gel (AV), coconut water (CW), and AV+CW in the ratio 1:1 (v/v). Data on root production and growth were collected four months after the application of treatments. Results indicated an absence of rooting of cuttings in the negative control. Rooting percentage was highest in AV+CW and lowest in the AV treatment which did not show a significant difference with either the controls or CW. In contrast, values of number of primary roots were highest in AV and lowest in IBA. Number of secondary roots, root system length and root fresh weight were significantly reduced by IBA. Root diameter was unresponsive to the treatments. The findings suggest that biostimulators are essential factors for rooting of Vitex diversifolia cuttings. While treatment with IBA, AV, and CW may have a comparable influence on rooting percentage, the combination of AV and CW may be a more potent promoter of the trait. In addition, the application of IBA may be less beneficial than the plant extracts for number and growth of roots.
