In: Journal of Agricultural Research Tanta Univeristy 2002.v.28(1)Summary: A trial was achieved at Orman Botanical Garden, Giza, Egypt during 2000 and 2001 seasons to study the effect of a commercial sea salt (NaCl) at the levels of 0, 2000,4000,6000,8000 and 10000 ppm in irrigation water on growth, flowering and chemical composition of two ornamental shrubs; Vitex agnus-castus. L. and Parkinsonia aculeata. L. The results show that no mortality was observed with increasing salinity levels although all vegetative and root growth traits of these two plants were declined, except for 2000 ppm level which increased vegetative growth of Vitex plants, aerial fresh and dry weights and root growth of Parkinsonia. Salinity concentrations above 4000 ppm delayed flowering of Vitex plants, whereas all concentrations reduced number of inflorescences/plant, inflorescence length (cm) and fresh weight (g) and number of seeds/inflorscence, except for the rate of 2000 ppm which slightly increased number of inflorescences/plant.
