    In this study the effect of Naphtyl Acetic Acid (NAA), Ascorbic Acid (AA) and Indole Butyric Acid (IBA) on rooting of mulberry and fig cuttings; and besides, the effect of Alar (B-9), and Salicylic Acid (SA) on bud burst of some peach, cherry and pear cuttings were investigated. NAA (100, 200, 400 ppm) increased significantly both rooting percentage and root dry weight in the hardwood cuttings of Bursa Siyahı fig variety. Also it had the same effect on the root dry weight of Ichinose mulberry variety in the experimental year of 1985 . On the other hand, AA (100, 500, 1000, 2000 ppm) had no significant effect on rooting percentage and root dry weight of mulberry and fig cuttings. NAA (100, 200 ppm) had also increased root dry weight of Ichinose cuttings in 1986. But IBA did not show promoter effect on the rooting of the cuttings of both Ichinose mulberry and Bursa Siyahı fig varieties. Alar (2000, 4000 ppm) delayed first bud burst 1-4 days, and mean bud burst 2-6 days in peach, cherry and pear cuttings in 1985. SA (500, 1000, 2000 ppm) delayed first bud burst 1-2 days and mean bud burst 1-4 days in cherry and peach cuttings. Alar (2000, 4000, 8000 ppm) delayed first bud burst 1-4 days and mean bud burst 2-8 days and SA (4000 ppm) delayed first bud burst 0-2 and mean bud burst 3-7 days in pear cuttings in 1986. Neither Alar nor SA affected the total bud burst percentages in the two years of experiment.
