The effects of temperature and exogenous auxin on cutting propagation of some junipers

From past to the present, cultural, medicinal, landscape and culinary use of junipers has contrib­uted it being one most widely distributed woody plants in world. Therefore, is so important that finding appropriate production methods obtain quality seedlings line with usage area. In present study, was tried determine best conditions applications on propagation by cuttings three juniper taxa including Juniperus communis L. ‘Hibernica’, chinensis ‘Stricta’, ‘Stricta Variegata’. For this purpose, two different greenhouse treatments (Greenhouse-1 air temperature at 20±2°C, rooting table 25±2°C humidity level 70±2%; Green­house-2 20±2°C 70±2%) auxin (Indole-3-Butyric Acid, Indole-3-Acetic Acid ?-Naphthalene Acetic concentrations 3000 5000 ppm) were designed. The highest percentages generally achieved Greenhouse-1. IAA ppm treatment for J. ‘Hibernica’ (93.33%) ‘Stricta’ (66.67%, also Greenhouse-2) IBA Var­iegata’ (60.00%) showed results. This which are investigated some taxa, a guiding feature producers ensure sustainable utilization junipers.
