Effects of Growth Regulators Application on Propagation with Hardwood Cuttings of the Black Mulberry

29312

Black mulberry (Morus nigra) is one of the species that are difficult to propagate. In this study the effects of different doses and combinations of growth regulators on rooting of hardwood cuttings from domestic Mulberry (Morus nigra) were investigated. The cuttings were obtained from the Malatya fruit research station in the middle of March and 15-20 cm length were prepared. Hardwood cuttings treated with 0, 4000, 6000, and 8000 ppm IBA and 3000 ppm IBA + 150 ppm NAA solutions by quick dip method. After keeping about 3 months in perlite in a greenhouse fogging with bottom heating, cuttings were removed. Rooting has not been in Control plants. The highest rooting ratio (% 66.7), average the number of root per cutting (3 root/cutting), average root length (43,4 mm) and ratio of survived cutting (%43.33) were observed in 8000 ppm IBA application. The rooting percentage increased with increasing in IBA doses
