Sažetak
Schefflera arboricola (Hayata) Merr. is propagated by leafy stem cuttings. In order to study the biochemical variations and vegetative traits of S. arboricola cuttings over the rooting period, an experiment was carried out on the basis of a randomized complete block design with 13 treatments and three replications. The experimental treatments were composed of indole-3-butyric acid (IBA), naphthaleneacetic acid (NAA), abscisic acid (ABA), salicylic acid (SA) and their combinations at different rates. It was found that hormone application had a favorable impact on rooting and increased rooting percentage in most treatments when compared to control. The application of different hormones influenced morphological traits to varying degrees. According to the findings, the highest rooting percentage was obtained from cuttings treated with 1000 mg L-1 NAA, the highest number of roots was obtained from those treated with 1000 mg L-1 NAA + 200 mL L-1 SA, and the longest roots from those treated with 1000 mg L-1 NAA or 100 µM ABA. Significant differences were observed between two studied ABA rates in chlorophyll contents and peroxidase content. The highest catalase activity was observed in cuttings treated with 1000 mg L-1 IBA + 50 µM ABA + 200 mL L-1 SA.
