Abstract:

The purpose of this study; within the scope of propagation of tea plant with hardwood cuttings, which is one of the vegetative propagation methods, the aim is to investigate the effects of 3 different Indole-3-Butyric Acid hormone doses and the presence of 2 different leaves on rooting on hardwood cuttings taken from annual shoots during the rest period. Hardwood cuttings have the opportunity to be supplied in a wider period during the compared to other cuttings types. For this purpose, hardwood cuttings taken from the tea orchards in Pazar district of Rize province were used. Control and three different doses of Indole-3-Butyric Acid (3000, 4000, 5000 ppm) were applied to hardwood cuttings, and also two different hardwood cuttings with half leaves and full leaves were applied. The study was carried out in a greenhouse with perlite environment concrete pads without bottom heating. The study was planned as three replications according to the factorial experimental design in randomized. The best results in hardwood cuttings were obtained from the application of 3000 ppm Indole-3-Butyric Acid hormone cuttings. The highest rooting rate was 70% and 66.6%, respectively, in the application of 3000 ppm Indole-3-Butyric Acid in whole and half-leaf cuttings; the lowest was found to be 48.3% in half leaf 5000 ppm Indole-3-Butyric Acid application. Considering all the results, it was concluded that the full-leaf hardwood cuttings applied with 3000 ppm dose of Indole-3-Butyric Acid hormone on rooting and root development of tea hardwood cuttings gave the best results and this application can be recommended.
