Abstract
Jojoba is a dioecious desert shrub which produces high quality oil used in cosmetics and lubrication.
An experiment was conducted to identify the most appropriate plant growth regulators and genotypes
for Jojoba propagation. A 4x4 factorial arrangement laid down in a randomized complete block design
was used with 16 treatments replicated 3 times. Treatments comprised of 4 factors of growth
regulators and 4 types of genotypes. The
Th e experiment was carried out for 5 months in 2013. The
variables sampled included roots, leaves and shoot. ANOVA was carried out using SAS statistical
package and means were separated using Duncan , s Multiple Range Test at p ≤ 0.05. Results showed
that Anatone
Anat one growth regulator gave significantly superior rooting of 24.2% for cuttings compared
with the control (11.5%). The male genotypes showed significantly higher rooting of 24.2
24.2-37.6%
compared with the females (2.2-7.6%).
(2.2 7.6%). Anatone is recommended for propagat
propagation of cuttings in a
polythene sheet tunnel since it is also cheap and readily available from agri
agri-veterinary shops. Further
research is recommended on screening of a wide range of genotypes especially the females and plant
growth regulators for future propagation
