	EFFECT OF SALINITY ON GERMINATION AND GROWTH OF ALFALFA, SUNFLOWER AND SORGHUM A.A. MALIBARI, M.A. ZIDAN, M.M. HEIKAL AND S. EL-SHAMARY Abstract: The effect of different levels of salinities on germination and growth of alfalfa (Medicago sativa), sunflower (Helianthus annuus) and sorghum (Sorghum bicolor) plants was studied. NaCl and CaCl₂ (1:1 w/w) @ 1000, 3000, 5000 and 7000 ppm in Hoagland solution were used. During germination stage, sunflower tolerated salinity upto 5000 ppm and alfalfa and sorghum upto 3000 ppm. During growth stage, dry matter, leaf area and pigment fractions in alfalfa and sunflower increased at low levels of salinity but decreased at higher levels. In sorghum plants growth parameters decreased at all the salinity levels. Depanment of Biology, Faculty of Science, King Abdulaziz University P. O.Box 9028, , Jeddah 21413, Saudi Arabia.
