Application Effects of Humidity and Different Hormone Doses on the Rooting of Prunus cerasifera Pissardii Nigra Softwood Top Cuttings

Ismail Hakkı Kalyoncu, Nilda Ersoy, Muhammet Emin Karalı


In this study in early july softwood top cuttings were taken from the ornamental plum (Prunus cerasifera Pissardii Nigra) tree growing in the campus of Konya Selçuk University. Effects of 90 % - 100 % air relative humidity in the misting system, a different IBA (Indole-3-Butyric Acid) hormone dose (control, 1000, 2000, 3000, 4000 and 5000 ppm) and a perlite rooting environment on the rooting capability and root formation were sought on these cuttings. When the rooting rate of the Prunus cerasifera Pissardii Nigra tree in the study was considered it was noticed that the highest rooting rate of 71.43 % was reached in the control group and the lowest rate of 23.81 % was reached with a 2000 ppm hormone dose application. The highest rooting number of 23.46 unit/cutting was obtained with a 4000 ppm hormone dose level. The lowest rooting number was obtained from control groups although there wasn’t any roots. The longest root with 4.08 cm length was obtained with a 3000 ppm dose level. The shortest root was obtained from the control group having any roots. The highest rooting surface length of 2.92 cm was obtained with a 5000 ppm level and the lowest rooting surface was obtained from the control group having any roots.
