Abstract
Abstract Jojoba [ Simmondsia chinensis (Link) Schnied] was introduced into the Barah semiarid area (lat. 14°N, long. 30°30′E) in Sudan. Jojoba is of great economic importance because of its liquid wax content. Bloss (1) reported that jojoba was assumed to be nonmycorrhizal. However, in a later investigation, he concluded that jojoba is mycorrhizal under natural conditions, but added that jojoba plants produced from seeds in the greenhouse for field plantings were not usually mycorrhizal. Because jojoba has been found to be mycorrhizal and growth response to mycorrhizae has been reported in woody plants (2), further investigation of the mycorrhizal status of jojoba in the seedling state, especially in the Sudan, is needed.
