Sexual propagation of Simmondisia chinensis (tink) Schn

Jojoba is considered as a valuable crop species regarding its tolerance to drought and soil salinity as well as its economical importance as an industrial crop. This species is used on soil conservation activities, against desertification, as an ornamental and landscaping plant and in some extend also can be considered as a nutritional plant. Seeds of Jojoba contain 50-60% liquid wax which is used in electronic, medicine, nutrition and cosmetic industries.
The result of this experiment showed that application of 70% ethanol for 5 sec followed by 1% (w/v) benomyl for 30 min and 1% (v/v)sodium hypochlorite containing 1-2 drops of liquid detergent for 15 min caused the highest seed surface sterilizing efficiency.
The highest germination rates (90%) were obtained when the seeds were incubated in a 27°C dark germinator for 5-13 days.
There was significant differences (P < 1%) among seed germination rates. In this experiment seed germination was examined as most convenience and low cost method of Jojoba propagation.
