EFFECTS OF DIFFERENT APPLICATIONS ON ROOTING CAPACITY OF BLACK ELDERBERRY CUTTINGS

Elderberry species (Sambucus spp.) grows mostly in wild form in the northern hemisphere. It is often used for landscaping riverbanks, as a windbreak, but also for human nutrition and medicinal purposes. This plant is used especially in the industrial field to obtain essence. In this study, the effects of some applications on rooting success in elder wood cuttings were investigated. For this purpose, in addition to 0, 2000, 4000 ppm IBA solution, a mixture solution of different Bacillus species (1.7X108 cfu/ml) was used. After the above-mentioned applications were applied to the wood cuttings taken from the plants during the resting period, they were taken into the perlite environment in the greenhouse at 22 0C. According to the results obtained, the number of roots per cutting was found to be between 11.3-22.4. Root lengths varied between 7.1-8.4 mm according to the applications. 2000 ppm IBA application was the application that increased both root length and root number the most. The study revealed that the rooting efficiency of black elderberry plant would be increased by IBA application.
