Effects of Different Media, Cutting Time and IBA Doses on Rooting of Rockspray Cotoneaster (Cotoneaster horizontalis Decne.) Cuttings

Abstract

Objective: In this study, the effects of different IBA doses and rooting media applied to the cuttings of rockspray cotoneaster (Cotoneaster horizontalis Decne.) taken at different times on rooting and root quality were investigated. Materials and Methods: In this study, rock spray cotoneaster (Cotoneaster horizontalis Decne.) plants growing in the Ondokuz Mayis University campus area were used as cutting resource. Cuttings with 10 cm length and 4 leaves taken from the current season semi-wood shoots of the plants in June, July and August were used as material. Cuttings were treated with Indole-3-butyric acid (IBA) at 3 different doses (500, 1000 and 2000 ppm) and control (0 ppm) and then planted in peat and perlite medium in +22°C under-heated pans in an unheated greenhouse. The greenhouse humidity was maintained above 70% with an automatic fogging-misting system, and shading was done with a green shade cloth starting from June. Rooting rate (%), root number (number/cutting), rooting degree (0-9), root length (cm) and the number of alive saplings in rooted cuttings transplanted into pots were determined in the cuttings removed two months after the planting date. The experiment was designed according to the split plot experimental design divided into randomized blocks with 3 replications and 20 cuttings in each replication. Results: It was found that different IBA doses and rooting media applied to leafy cuttings taken at different times from spreading cotoneaster were affected by rooting, main root lengths, number of roots, degree of root formation and the proportion of surviving or living plants. The highest rooting rate with 98.33% was obtained in cuttings taken in July and planted in peat medium to which 500 ppm IBA was applied. “peat x August cuttings x 1000 ppm IBA dose” gave the best result with 8.64 cm in root length. “perlite x June cuttings and 1000 ppm IBA dose” stood out in root number with 6.89 pieces while “peat x July cuttings x 500 ppm IBA dose” gave the highest result in rooting degree with 5.91. Conclusion: It was determined that rooting and root quality in propagating the spreading cotoneaster with green and semi-woody cuttings in bottom heated pans were affected by the cutting time, IBA doses and rooting media. Accordingly, the highest rooting rate of 98.33% was obtained from cuttings taken in July and planted in peat medium after applying 500 ppm IBA. The root length was the highest with 8.64 cm in cuttings taken in August and planted in peat medium after applying 1000 ppm IBA.
