Abstract: Background: Application of antioxidant materials like ascorbic acid to alleviate salinity stress and promote jojoba growth is a high effectiveness target, whereas, jojoba is an attractive industrial and biofuel crop. Materials and Methods: A greenhouse experiment was conducted in the National Research Centre at Dokki, Giza, Egypt to evaluate the effect of different salt stress degrees on the growth, photosynthetic pigments (chlorophyll and carotenoids) and mineral status characters of jojoba plant which sprayed by ascorbic acid. The treatments were as follows: (1) Irrigation by two concentrations of diluted seawater (S1 = 2500 and S2 = 5000 ppm), the control treatment irrigated with tap water (TW = 250 ppm), (2) Spraying ascorbic acid with two concentrations (As1 = 100 and As2 = 200 ppm), the control plants received the same quantity of distilled water (C = distilled water). Results: Irrigation with seawater negatively affected growth parameters in spites of that the differences not great enough to reach the significant levels. The high salinity level used sharply decreased chlorophyll a, chlorophyll b, carotenoids and total chlorophyll concentrations in comparable with that irrigated regularly with fresh water. Ascorbic acid application increased stem, leaves, shoot and seed protein, compared to control (foliar with distilled water), whereas, As2 was super than As1. Carbohydrate and carbohydrate/protein ratio also were increased with ascorbic acid application but As1 was the superior. Conclusion: Generally, it can be used diluted seawater in irrigation of jojoba plant with spraying ascorbic acid to alleviate the harmful effect of salinity.
