Genotype Evaluation and Moisture Requirements for Cultivated Jojoba

摘要

Jojoba, Simmondsia chinensis is a plant that offers possibilities as a new crop for areas in Arizona where water is scarce and expensive. The Avra Valley is one such area. Two impediments to jojoba cultivation in the Avra Valley are (a) the amount of supplemental irrigation water needed for successful cultivation of jojoba are not known, and (b) planting-stock presently available is not cold-tolerant enough for that area. A study has been initiated to study several irrigation regimes on jojoba performance in this valley and to identify cold-tolerant individuals which could be used for variety improvement.
