Özet

Autumn olive berry is used as functional food due to the very high content of lycopene. It is a deciduous, perennial, temperate and/or subtropical berry fruits and has a woody bush. Autumn olive leaves, flowers, berries and bushes can be used for many purposes. It grows well at sunny areas and tolerates dry conditions with salty, clay, sandy and different pH soils. Autumn olive berry can be diverse with its seed eaten by birds. Cultivated autumn olive berry types generally propagate by cuttings. In the present study, hardwood, leafy green wood and semi hardwood cuttings taken from mother plants of autumn olive berry at March 15, May 15 and July 15. All type of cuttings applied with 0 ppm (control), 500 ppm, 1,000 ppm and 2,000 ppm Indole-3-butryic acid (IBA) doses. Cuttings were planted in benches with perlite under misting at greenhouse conditions for rooting. The effect of cutting time and IBA application on the rooting rate (%), root number, rooting degree (1-9), diameter and length of the saplings (cm) and salable sapling rate (%) were determined. Pearson correlation among the features studied was also calculated. Cuttings taken at May with 1,000 or 2,000 ppm IBA and June with 500 ppm gave the highest rooting rate (97.33%). Root length is the best (11.90 cm) at May cuttings with 500 ppm IBA. May cuttings with 1,000 ppm IBA gave the best salable sapling rate (89.33%). The best cutting time was 15 May and the best IBA dose is the 1,000 ppm for most characteristics, investigated
