Effect of cutting severance date on rooting success and Bio-algeen S-90 application on further growth of cherry laurel Prunus laurocerasus L.

Cherry laurel (Prunus laurocerasus L.) mostly used in horticulture for planting as living hedge, was propagated vegetative by cuttings. The aim of this research was to clear the influence of cutting severance date on rooting ratio and effects of biostimulants using in further cultivation of rooted cuttings. Measured parameters were: the number of rooted cuttings, the number of cuttings with callus formation and the number of not successfully survived cherry laurel cuttings. The results indicated significant influence of severance date of successful rooting of cuttings. Rooting rate ranged between 94-98% for cuttings taken in middle till end of October and 40-79% for cuttings taken in November. A significant effect of Bio-algeen S-90 used foliar in concentration of 0.2% was detected on plant height after 14 days cultivation. After six week cultivation, a significant effect in the watering treatment in 1.0% concentration of Bio-algeen S-90 on the plant height was detected. Although, we found no significant difference in leaf number between control, foliar treatment 0.2% and watering with 1.0% Bio-algeen S-90 after 14 days cultivation but, a significant effect of leaf number in watering treatment, six weeks after application period was confirmed.
