THE EFFECTS OF CUTTING LENGHT AND IAA HORMONE ON THE ROOTING OF EUONYMUS JAPONICUS CUTTINGS
Abstract
The aim of this study was to determine of the best size cutting length and concentration of IAA on rooting of Euonymus cuttings in the greenhouse. A factorial experiment was carried out in a compeletly randomized block design with 3 replications where each replication was comprised of 10 plantlets. Treatments were comprise of three stages of cutting length (7, 15 and 22 cm) and five stages of IAA concentrations (0, 500, 1000, 1500 and 2000 mgL-1). Morphological and physiological traits such as number and leaf area, fresh and dry weight of plant, number and length of root, number and length of shoot and number of bud were recorded. The result indicated that the cutting length and concentration of IAA was significant on some of quantity charactristics of Euonymus. The best response was related to cutting length of 15 cm and 500 mgL-1 IAA.
