The effect of different IBA doses on rooting in soft-wood cuttings of rootstock candidate sweet cherry, sour cherry and mahaleb genotypes

Abstract

This study was carried out to investigate the effect of different IBA (Indole Butyric Acid) concentrations on rooting in soft-wood cuttings of rootstock candidate sweet cherry, sour cherry, and mahaleb genotypes in a plastic greenhouse with underfloor heating and mist propagation of Black Sea Agricultural Research Institute. 500, 1000, and 2000 ppm IBA doses were applied to the soft-wood cuttings taken in june. Perlite was used as propagation medium and rooting medium was disinfected with methyl bromide before planting. The study was planned according to a randomized plot design with three replications and 20 cuttings in each replication. The rooting rate (%), number of roots (piece), number of branching roots (piece), and root length (mm) were investigated. The highest rooting ratio of 59 % (08 K 056) was obtained from the 1000 ppm IBA application, while the lowest rooting ratio of 22.50% (55 K 104) was obtained from the 1000 ppm IBA application.
