ABSTRACT

The effects of cuttings harvesting date, rooting temperature and hormone powder on rooting of Aubrieta cultorum cuttings were investigated. The percentage of rooted cuttings varied depending on rooting dates. In the summer (July 6 and August 17) 98% and 98.6% of cuttings formed adventitious roots. In the autumn (September 28 and November 9) 100% of cuttings formed adventitious roots. However, there were big differences in number of roots per cutting and root system quality depending on a date, temperature and rooting powder applied. The cuttings formed root system of the best quality with the highest number of roots, when they were prepared on September 28 and treated with Ukorzeniacz A (0.3% IBA, 0.1% Benomyl and 1% Captan). Cuttings treated with Ukorzeniacz B (0.2% NAA, 2.5% Benomyl and 1% Captan) and Ukorzeniacz AB (0.3% NAA, 0.05% IBA, 2% Benomyl and 1% Captan) had lower number of roots and lower quality but higher than control cuttings. Temperature 10°C was better than 15&de

Key words: Aubrieta cultorum, cuttings, rooting dates, IBA, NAA, temperature..
