Abstract: Assay for salt tolerance and drought resistance of transgenic wheat e xpressing betaine aldehyde dehydrogenase, obtained through part icle gun method,were conducted under simulated salt drought s tress condi tion. The resul ts in dicated that the transgenic wheat has many obvious advanta ges over its donor plants, such as the greater germinating ability under osmotic st ress up to-0. 3 Mpa, the more vigorous development of seedlings, especially the well developed roots under drought st ress condi tion, as well as the improved plasma membrane protection of excised leaf and the lower transpi ration rate under field condi tion. But the water los s rate for e xcised leaf was not obviously di fferent from its donor cont rol plants.
