Özet

This study was conducted to investigate the effects of different IBA doses on rooting capacity of Cherry laurel (Prunus laurocerasus L.) types in greenhouse conditions under mist propagation unit in 2008 - 2009. This species has an economic and important value for medicinal and pharmaceutical industry. Determination of suitable conditions for cutting propagation of different types is too important for economic propagation. The cuttings collected in July were like semi hardwood cuttings and are treated with 1, 2, 4, 6 and 8 g/l Indole-3-butryric acid (IBA). The results were taken after 90 days and were evaluated using the analysis of variance (ANOVA) and Duncan test with a significance value P <= 0.05. The rooting rate (%), average root number (roots/cutting) and average root length (cm) were determined. The results showed that rooting rate and root quality were changeable according to types. The maximum rooting rates were obtained with 2 or 4 g/l IBA for most of the types. 1 or 2 g/L IBA obtained the maximum root length and increased the rooting length and root quality compared with control. The average number of roots increased in 2 g/l IBA and high doses of IBA resulted with breakable root formation that reduced the success rates in transplantation stages.
