Abstract
Jojoba (Simmondsia chinensis, Link) Fam. Simmodsiaceae, is considered one of the most practical and scientific solutions for desert plantation in Egypt. Hot summers, warn winters, desert soil, minimal water, great salinity tolerance, lesser need for fertilizers, and generous financial income, are certainly most encouraging to plant jojoba in Egypt.It, originally, grow south west of the USA and northern Mexico.An evergreen wild shrub that could live for more than 100 years. A full green shrub is 2-4 m high with a 15 m long root. Jojoba seed can yield up to 50 % pure oil chemically classified as liquid wax that gives it a great advantage as natural oil for industrial purposes, which also make it, environmentally, safe.
The present investigation was conducted during two successive seasons 2003 and 2004 in the Nursery and Laboratory of Ornamental Plants Division, Horticulture Department, Faculty of Agriculture, Minia University. The aim of such experiment was to study the influence of irrigation at three levels (60 %, 80 % and 100 % F.C.) as the main factor; salinity at three treatments (0.0 . 0.4 and 0.8 % from NaCl + CaCl2, 1:1 by weight) as the sub-unit factor and GA3 at three concentrations (0.50 and 100 ppm) as the sub-sub unit factor, on different vegetative growth characters and some chemical constituents of jojoba seedlings. The experiment was arranged in a split-split-plot design.
