Abstract
Although few seedlings of jojoba [Simmondsia chinensis (Link) C. K. Schneid] developed foliar symptoms when their roots were waterlogged at 23°C for 42 days, root systems of all plants were irreversibly damaged. At 33°, symptoms developed more rapidly, but again all plants died when treatments were prolonged to obtain foliar effects on a high proportion of plants. The limit of survival at 33° was when about 50% of the seedlings expressed symptoms. Jojoba is intermediate in sensitivity to waterlogging based upon direct comparisons with walnut (very sensitive) and pear (very tolerant).
