The present study was carried out on jojoba “Simmondsia chinensis-Link” plants during two consecutive 2002 & 2003 experimental seasons. In this experiment the possibility of using leafy soft stem cuttings for propagating jojoba vegetatively was investigated. Herein, two factors namely: a – collecting / exiting date of cuttings from mother trees (April, May, June and July) and b- dipping in NAA , IBA , PP333 solutions and tap water as control, as well as their possible combinations were evaluated pertaining their influence on some rooting and vegetative growth measurements of cuttings. The results showed that, dipping of mid May prepared cuttings in different growth regulators solutions significantly increased all rooting and growth measurements i.e., (rooting %, number and length of developed roots), and (average length ;diameter of the main shoot and total number of leaves per every rooted cutting) compared with analogous ones of control (dipping in water). |
