Effects of Indole-3-Butyric Acid (IBA) and Cutting Type on Rooting of Camellia sinensis (L.) O. Kuntze

Abstract

The objectives of this study were to determine the effect of cutting type, and IBA (Indole-3-butyric acid) on rooting of Turkish tea (Camellia sinensis (L.) O. Kuntze) clone ‘Fener-3’ cuttings. The cuttings collected at 1 September in 2012. After pre-treating with 0, 2000, 4000 and 6000ppm IBA, the cuttings with full leaf and half leaf rooted in perlite medium in unheated trays under misting glasshouse for 60 days. And then, they all were removed from media to determine the survival rate, rooting rate, root number, root length, root diameter and root quality. In conclusion; survival percentages varied from 70.0% to 90.0%. The highest survival percentage (90%) was observed on full-leaf cuttings treated with 6000 ppm IBA. The rooting percentage varied from 43.3% to 78.3%. The best results were obtained for rooting (78.3%), which is 6000 ppm IBA doses, was gathered with full- leaf cutting. The root lengths varied from 9.83 to 14.77cm. The best result (14.77cm) was taken from 6000 ppm IBA dose based on the full leaf cutting. The root diameters varied from 0.99 mm to 1.30mm. The best result (1.30mm), prepared the full leaf cuttings, 6000 ppm IBA doses has been application. The number of root varied from 3.40 to 6.37 units. The best results (6.37 units) were taken 6000ppm IBA doses based on the full-leaf cuttings. The quality of the root varied from 1.93 to 3.50 points. The best result (3.50 points) was taken 6000 ppm IBA doses based on the full-leaf cuttings. Among all parameters the best type of cutting was full-leaf cutting, and 6000 ppm IBA was the most appropriate dose. The lowest rooting and rooting quality were taken from control (0 ppm IBA) treatment.
