Description [ Edit ]
Vegetative characteristics [ Edit ]
Jojoba grows as evergreen, richly branched shrub , whose stature heights vary from 0.5 to 4 meters, usually 2 to 2.5 meters. In a natural environment, the shrubs can be about 200 years old. [1] He has taproots which can penetrate about 6 feet deep in the ground. Abnormal Secondary growth occurs by a concentric cambium. The light brown wood is hard. The bark is smooth.

The opposite, short-stalked leaves are simple, leathery, entire and 2-4 inches long. Anomocytische stomata are located in approximately the same number on both leaf surfaces. Stipules absent.

Inflorescences and flowers [ Edit ]
Simmondsia chinensis is a dioecious getrenntgeschlechtige ( dioecious ) plants . The male flowers are terminally together several and the female flowers are usually solitary in the leaf axils. The small, unisexual, radial symmetry flowers are usually fünfzählig (rarely four or sechszählig). The male flowers are yellow and 3-4 millimeters in size. The male flowers contain two circles with usually five (rarely four or six) of free, fertile stamens . The female flowers are small and light green. Three carpels are a top permanent, dreifächerigen ovary adherent. Each ovary compartment contains a suspended, anatrope, bitegmische ovule . Three free stylus are present in the papillary scars. The pollination is carried on the wind or by insects. The sepals of the female flowers are durable and enlarge until fruit maturity at 10 to 20 millimeters.

Fruits and seeds [ Edit ]
There are ovoid, lokulizidale, dreifächerige, usually one-seeded fruit capsule formed. The capsule fruit is ripe 3 to 6 months after fertilization and open to release the seeds. The brown, wrinkled seeds have about the size of a small olive. The tall, straight embryo is well developed.

Ingredients and number of chromosomes [ Edit ]
Simmondsia chinensis contains proanthocyanidins. There are calcium oxalate crystals accumulate . The embryo or cotyledons in the seeds contain cyanogenic glycosides and liquid waxes from esters with high molar mass, there are mono- carboxylic acid esters of acetic acid , as storage compounds. [2]

The haploid chromosome set consists of 13 chromosomes . In the somatic cells of the plant is tetraploid ago, the chromosome number is so 4 x 13 = 52nd [3]

Occurrence [ Edit ]
The Jojoba grows in semi-deserts and deserts . He is in Mexico , California and Arizona in the area of Sonora native -Wüste. Its botanical epithet chinensis is based on a mistake, because a botanist seeds mistake in the initial determination with samples of other plant species from the Chinese Empire muddled. The jojoba shrub is native to China.

Jojoba is commercially except in the USA nor in Israel , Argentina , Peru and Australia cultivated. Their ecological importance lies in the protection against soil erosion and the creation of a favorable microclimate .

The populated by Jojoba habitats ranging from warm temperate deserts , with little or no frost on thorn forest to dry forest . The annual rainfall was between 200 and 1100 mm, mm, in extreme cases, less than 125 tolerated. The best growing conditions are about 300 mm. With precipitation of about 75 mm Jojoba grows up to 1 meter high, with rainfall of 250 to 400 mm, it reaches up to 5 meters Height. The average annual temperature may 16-26 ° C. Jojoba tolerates full sun and temperatures between 0 and 47 ° C. For mature shrubs, the temperature can drop to -10 ° C, but seedlings are sensitive to frost already slightly below 0 ° C. The floors can have pH values ​​of from 7.3 to 8.2. Jojoba grows best in well-drained soil, coarse, well-ventilated desert soils that are neutral to basic, in which phosphorus occurs. [1]

Cultivation [ Edit ]
The germination of jojoba seeds is after six months 99% and after 11 years still 38% for open storage. The best germination success lie in basic sand at temperatures from 27 to 38 ° C. The cultivation of cuttings has the advantage that one can reproduce the exact amount of male and female specimens; the Bewurzlungszeit lasts about 38 days. [1]

Hedges are planted with 4 to 5 meters, 2 meters, respectively and gap spacing between the individual plants. Ideal fertile ground is a pH greater than 5, less than 5% of the plants should be male, to ensure pollination; for example, 500 female and 50 male specimens per hectare, but it can also, in another method of cultivation up to 2500 copies per hectare are planted. apomictic plants are known, this would reduce the need for Bestäuberpflanzen. The first yield can be achieved after 3 to 5 years, the income maximum is 12 years. [1]

Terms [ Edit ]
Are harvested, the "nut-like" seed , which a liquid at room temperature wax (ie it is not, as with other vegetable oils to a rich oil) [4] contain, at a level of about 50%.

Experimented successfully, including in Arabia , even with the application of eco-friendly because of natural sulfur-free fuel for diesel engines ; only the addition of some methanol is necessary. Here could be opened in the coming decades, a commercial niche. Since jojoba wax is a renewable resource, the emitted during combustion is carbon dioxide bound at sustainable economy by growing plants and thus contributes not warming at.

Of the indigenous peoples , the seeds were roasted and boiled to obtain the liquid wax, and processed into foods such remedies.

Another ingredient of the seed is Simmondsin . Seed powder with high Simmondsin content was added in early 2007 food and particularly praised. This food additive is forbidden by law in Europe. The Federal Institute for Risk Assessment advises to take them off, because the seeds have been shown in animal studies to be highly toxic. [5]
