Karadut'un (Morus Nigra L.) Odun Ve Yeşil Çeliklerle Çoğaltılması Üzerine Araştırmalar

Abstract

This research was conducted to determine the effects of Indole-3- butyric acid (IBA) doses and planting times (respectively, at green cuttings 0, 2000, 4000, 6000 ppm and 1 July-12 August; at hardwood cuttings 0, 1000, 2000, 4000 ppm and 22 Nowember) with black mulberry (Morus nigra L.) green cuttings and hardwood cuttings on rooting behaviour during 1995 year. The cuttings were planted in perlite at mist unit to high plastic tunnel. For green cuttings were applied mist.For hardwood cuttings were applied bottom heat (18-21 °C). The highest rooting ratio (55.00 %), callusing ratio (56.67 %), average number of roots (4.34 pieces), average lenght of roots (49.02 mm), quality of root (2.58 point), practical cutting ratio at plant production (40.00 %) and active cutting ratio (70.00 %) were abtained by 6000 ppm IBA concentrations in green cuttings. Generally, for rooting behaviour second planting time green cuttings were found better than fisrt planting time green cuttings. At hardwood cuttings, the highest rooting ratio (56.67 %) and average number of roots (2.53 pieces) were abtained by 4000 ppm, practical cutting ratio at plant production (33.33 %) was determined by 2000 ppm and in other characteristics were found by 1000 ppm IBA concentrations.
